Highlights in Proxmox Backup Server 4.0

Based on Debian 13 “Trixie”

This core update is based on Debian 13 “Trixie”, bringing the latest Debian release as foundation for Proxmox Backup Server including newer packages, improved hardware support, and enhanced security. Proxmox Backup Server is using a newer Linux kernel 6.14 as stable default enhancing hardware compatibility and performance, and includes ZFS 2.3.3.

Support for S3-compatible object storage

This version introduces native support for S3-compatible object storage as backend for backups. By supporting the S3 API, Proxmox Backup Server enables users to access highly scalable and cost-effective public and private cloud environments for storing backup data. To improve performance and reduce cost, Proxmox Backup Server leverages a local cache and minimizes API calls to the S3 backend by internally retaining frequently used backup metadata and data chunks. While each S3 datastore is exclusively managed by a single Proxmox Backup Server instance, the underlying object storage’s contents remain reusable if the original instance goes offline, ensuring robust disaster recovery capabilities.

Live RAIDZ expansion

Proxmox Backup Server comes with ZFS 2.3.3 which now allows to expand existing RAIDZ pools with minimal downtime. This enhancement enables organizations to scale their ZFS storage on demand, adding capacity as needs grow without upfront over-provisioning or future disruptions. The ability to incrementally add new drives directly to an existing RAIDZ virtual device (vdev) reduces costs, ensures the continuous availability of data, and significantly increases flexibility.

Automatic sync jobs for removable datastores

This version introduces a significant enhancement for backup automation: Users can now configure sync jobs to run automatically each time a relevant removable datastore is mounted. By simply setting the new “run-on-mount” flag on a sync job, Proxmox Backup Server further simplifies critical backup procedures, ensuring data is consistently synchronized with minimal manual intervention.

Proxmox Backup Server seamlessly integrates into Proxmox Virtual Environment – users just need to add a datastore of Proxmox Backup Server as a new storage backup target to Proxmox VE.

Proxmox Virtual Environment 9.0 with Debian 13 released

2025-08-05T10:08:12+02:00

VIENNA, Austria – August 05, 2025 – Leading open-source server solutions provider Proxmox Server Solutions GmbH (henceforth "Proxmox"), celebrating its 20th year of innovation, today announced the release of Proxmox Virtual Environment (VE) 9.0. Main highlight of this update is a modernized core built upon Debian 13 “Trixie”, ensuring a robust foundation for the platform.

Proxmox VE 9.0 further introduces significant advancements in both storage and networking capabilities, addressing critical enterprise demands. A highlight is the long-awaited support for snapshots on thick-provisioned LVM shared storage, improving storage management capabilities especially for enterprise users with Fibre Channel (FC) or iSCSI SAN environments. With newly added “fabric” support for Software-Defined Networking (SDN), administrators can construct highly complex and scalable network architectures.

Highlights in Proxmox Virtual Environment 9.0

Debian 13 “Trixie” at the core

This core update is based on Debian 13 “Trixie”, bringing the latest Debian release as foundation for Proxmox VE including newer packages, improved hardware support, and enhanced security. Proxmox VE is using a newer Linux kernel 6.14.8-2 as stable default enhancing hardware compatibility and performance.

Also, updates to the latest versions of leading open-source technologies for virtual environments like QEMU 10.0.2, LXC 6.0.4, Ceph Squid 19.2.3, and ZFS 2.3.3 are included. ZFS now supports adding new devices to existing RAIDZ pools with minimal downtime. For existing users of Proxmox VE 8.4 or older versions, an extensively tested and detailed upgrade path is available to enable a smooth upgrade.

Snapshots for thick-provisioned LVM shared storage

Virtual Machines (VMs) utilizing thick-provisioned LVM shared storages, such as those backed by iSCSI or FC-based SANs, now benefit from snapshot functionality out of the box. This is achieved by implementing snapshots as volume chains, where a volume based on a snapshot only records differences to its parent snapshot volume. Directory, NFS, and CIFS storages also gain additional support for snapshots as volume chains.

This new feature provides a powerful and highly requested capability for customers with traditional SAN infrastructure who have historically relied on clustered file systems. While direct integrations from many storage vendors continue to grow, this new feature closes the gap by providing a storage-independent solution for snapshots. This gives customers the independence to seamlessly manage their snapshots regardless of their hardware, without compromising on convenience.

New Fabrics feature for the SDN stack

This release enhances the SDN capabilities with the introduction of an SDN Fabrics feature, designed to simplify the configuration and management of complex routed networks. Engineered for reliability, SDN Fabrics facilitates multiple paths between nodes and automatic failover across Network Interface Cards (NICs), enabling the configuration of robust two-layer spine-leaf architectures for improved network redundancy and performance.

This new feature simplifies the management of dynamically routed networks which can for example be used as Ethernet VPN (EVPN) underlay or full-mesh networks for Ceph. The SDN stack in Proxmox VE gains support for two different routing protocols, OpenFabric and OSPF, and provides intuitive tools for the simplified configuration and precise management of those dynamic routing protocols.

Affinity rules in High Availability (HA) clusters

The Proxmox team introduces HA resource affinity rules to enable fine-grained control and flexibility over resource placement in HA clusters, ensuring optimal performance, enhanced resiliency, and minimized latency for critical workloads. To better control complex, interconnected applications, the new HA Resource Affinity Rules allow administrators to precisely define how virtual machines and other HA resources are distributed across a cluster.

Interdependent HA resources, such as for example an application server and its associated database, can be kept together on the same physical node to minimize network latency. For services requiring maximum redundancy, like multiple VMs running the same mission-critical application, the rules can ensure these instances are kept on different nodes. This increases fault tolerance and ensures resiliency even during HA failovers.

Enhanced mobile interface

The Proxmox VE mobile interface has been thoroughly reworked, using the new Proxmox widget toolkit powered by the Rust-based Yew framework. The redesigned interface provides quick access to service overviews and includes essential management functions, including starting and stopping virtual guests and basic configuration. It is now easier than ever for users to access fundamental functionalities of Proxmox VE directly from their mobile browsers.

Availability

Proxmox VE 9.0 is available for download. The ISO contains the complete feature-set and can be installed on bare-metal. The virtualization platform from Proxmox comes stocked with all the essential management tools, as well as an easy-to-use, web-based user interface. This allows for simple, out-of-the-box management of the host, either through the command line or a standard web browser.

Seamless upgrade instructions from Proxmox VE 8 to 9 are available. It’s also possible to install Proxmox VE 9.0 on top of Debian.

License: Proxmox Virtual Environment is free and open-source software, published under the GNU Affero General Public License, v3.

Proxmox Backup Server 3.4 released

2025-04-10T11:17:50+02:00

VIENNA, Austria – April 10, 2025 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") today announced the release of Proxmox Backup Server version 3.4. Designed to address enterprise data protection needs, this latest version of the open-source backup solution introduces new capabilities that further improve performance and usability.

Highlights in Proxmox Backup Server 3.4

Optimized Performance for Garbage Collection (GC): To increase storage efficiency through deduplication, backup data in Proxmox Backup Server is saved as chunks. In order to free up storage space after backup snapshots have been deleted, a garbage collection (GC) process identifies and cleans up unreferenced backup data chunks. This version 3.4 optimizes the GC mechanism and integrates a cache to reduce the number of expensive file metadata updates. While this enhancement increases memory usage, it substantially reduces execution time, resulting in faster and more efficient garbage collection. The caching mechanism can be fine-tuned on a per-datastore basis.
Granular backup snapshot selection for sync jobs: Offsite backups are of great interest for data security and therefore Proxmox Backup Server provides sync jobs to push or pull backup snapshots to and from remote Proxmox Backup Server instances. Group filters already allow the selection of which backup groups should be synchronized. In this latest version, the selection functionality has been extended to allow exclusive synchronization of encrypted or verified backup snapshots.
Static build of Proxmox Backup client: While Proxmox Backup Server is tightly integrated with Proxmox VE, its command-line client can also be used outside of Proxmox VE. A new statically-linked binary of the command-line client makes it easier to create file-level backups of arbitrary Linux hosts.
Increased throughput for tape backup: Since version 3.4, Proxmox Backup Server now allows to increase the number of worker threads when reading chunks during tape backup, which can significantly increase the throughput in certain setups.
Latest versions of open-source technologies: This version is based on Debian 12.10 (“Bookworm”), but uses a newer Linux kernel 6.8.12-9 and includes ZFS 2.2.7 (with compatibility patches for Kernel 6.14). While the kernel 6.8.12-9 is the stable default, Linux kernel 6.14 can optionally be installed for better support of the latest hardware.

Proxmox Backup Server seamlessly integrates into Proxmox Virtual Environment—users just need to add a datastore of Proxmox Backup Server as a new storage backup target to Proxmox VE.

Availability

Proxmox Backup Server 3.4 is now available for download. Users can either update their version of the solution or install the ISO image on bare-metal using the Installation Wizard. Distribution upgrades from older versions of Proxmox Backup Server are possible via APT. Optionally, Proxmox Backup Server can be installed on top of Debian.

License: Proxmox Backup Server is free and open-source software, published under the GNU AGPLv3.

Enterprise Support: For enterprise users, Proxmox Server Solutions offers a subscription-based support model, which provides access to the extensively tested Enterprise Repository, with regular updates via the web interface, as well as technical support on a subscription basis. Prices start at EUR 540 per server, including unlimited backup storage and unlimited backup-clients.

Live migration with mediated devices: Mediated devices allow physical hardware resources to be partitioned into multiple virtual devices. It is now possible to migrate running virtual machines (VMs) which have mediated devices such as NVIDIA vGPU in use. Within a cluster, live migration to another node is possible if hardware and driver support for live migration is equally available on the target node. An available platform with support for live migration is NVIDIA vGPU. Additionally, the new ‘pve-nvidia-vgpu-helper’ tool simplifies the setup of NVIDIA vGPU drivers.
API for third-party backup solutions: Proxmox VE now provides an API simplifying the development of plugins by external backup solution providers. Third party backup solutions can now directly implement backup and restore functionalities in Proxmox VE, and make use of advanced features. Third-party backup providers can implement a plugin that is fully integrated in the backup stack and in the web interface of Proxmox VE. This gives third-party backup solutions the opportunity to enhance the efficiency, reliability, and manageability of their backup and restore features in Proxmox VE.
Virtiofs directory passthrough: Version 8.4 offers the functionality to share files and directories directly between a host and the VMs running on that host. This is achieved through the use of virtiofs, which allows VM guests to access host files and directories without the overhead of a network file system. Modern Linux guests support virtiofs out of the box while Windows guests need additional software to use this feature.
Latest versions of open-source technologies: Proxmox VE 8.4 is based on Debian 12.10 (“Bookworm”), but uses the Linux kernel 6.8.12 as stable default and the newer kernel 6.14 as opt-in.

Proxmox Mail Gateway 8.2 released

2025-02-27T12:35:41+01:00

VIENNA, Austria – February 27, 2025 – Enterprise software developer Proxmox Server Solutions GmbH ("Proxmox" or the "Company") today released Proxmox Mail Gateway 8.2, the latest version of its open-source email security solution. The Mail Gateway platform is a complete operating system based on Debian 12.9 “Bookworm”, but defaulting to the newer Linux kernel 6.8 and allowing for opt-in use of kernel 6.11. It includes ZFS 2.2.7 and SpamAssasin 4.0.1 with updated rulesets.

The anti-spam and antivirus filtering solution functions as a full-featured mail proxy, that is deployed between the firewall and the internal mail server. It protects organizations against threats, such as spam, viruses, Trojans, and phishing emails.

What’s new in Proxmox Mail Gateway 8.2

Single sign-on: This version simplifies access management by integrating support for multiple authentication realms in the backend login. This eliminates the need to manage specific authentication details, enabling administrators to log into Proxmox Mail Gateway using single sign-on (SSO) authentication schemes with the new OpenID Connect as the first supported authentication protocol. This enables logging in through public as well as self-hosted services like Keycloak, Zitadel or LemonLDAP::NG.
Enhanced rule system: The Proxmox development team adds further improvements to the configuration options of the comprehensive object-oriented rule system, by which the mail flow can be controlled and filtered. The filtering of the mail's content by Content-Type can now be configured to ignore information from the filename and the Content-Type header field, and to rely solely on file signature based detection, allowing for accurate filtering of attachments. Furthermore, the filtering of mail header fields can now be restricted to the top header section, thereby providing the option to exclude headers in attached emails from the filter.
DKIM signature for emails generated by Proxmox Mail Gateway: Users can now set the From-header for emails generated by Proxmox Mail Gateway, like for example for notifications from the rule system, admin reports, or backup notifications. These emails are signed with DKIM if the installation uses the header information to obtain the domain for signing.
Automated and unattended installation: Proxmox Mail Gateway now supports automated and unattended installation making large deployments significantly easier. Proxmox offers a ‘proxmox-auto-install-assistant’ tool that fully automates the setup process on bare-metal. Automated installation allows for the rapid deployment of Proxmox Mail Gateway hosts without the need for manual access to the systems, saving time and reducing the risk of errors. To use this method, an answer file must be prepared with the necessary configuration settings for the installation process. This file can be provided directly in the ISO, on an additional disk such as a USB flash drive, or over the network. Tailor-made configurations for customized deployments can be achieved by running a custom script on first boot after an automated installation.

Availability

Proxmox Mail Gateway is released under the GNU Affero GPL, v3 and is available as an ISO download, which can be installed on bare metal or on a virtual machine. The ISO contains an installation wizard that automatically installs and configures all the necessary components on the host. This eliminates the need for manual configuration later. The ISO contains the complete feature-set and is available for download.

Additionally, you can install Proxmox Mail Gateway as a container appliance inside Proxmox VE.

Proxmox Backup Server 3.3 released

2024-11-28T11:21:48+01:00

VIENNA, Austria – November 28, 2024 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") today announced version 3.3 of its open-source server backup solution. The enterprise solution for backing up and restoring VMs, containers, and physical hosts supports incremental backups, deduplication, Zstandard compression, and authenticated encryption.

Enhancements in Proxmox Backup Server 3.3

New "push" direction for sync jobs: Sync jobs let users create offsite backups by syncing datastore contents between onsite and offsite Proxmox Backup Servers. Previously, the offsite server had to "pull" backup snapshots from the onsite server. Now, with the new "push" option, the onsite server can send backups to the offsite server, even if the offsite server can't initiate the network connection.
Support for removable datastores: Proxmox Backup Server stores backup snapshots in so-called datastores, and multiple datastores can be configured as needed. With this version, it is now possible to create datastores on removable storage media. Such a "removable datastore" can be used across multiple servers. Using the web interface or the command line, the storage medium can be removed by unmounting the "removable datastore." The datastore can then be re-added by remounting it—either on the same Proxmox Backup Server instance or a different one.
Webhook target for the notification system: The flexible notification system in Proxmox solutions uses a matcher-based approach to route notifications to various target types, allowing for granular control over when, where, and how notifications are sent. The new webhook notification target enables users to trigger HTTP requests for events like sync jobs, backup verification, or garbage collection. It supports customizable request headers and body content, allowing for seamless integration with any webhook-compatible service.
Faster host and container backups: When backing up host filesystems or containers from Proxmox VE to Proxmox Backup Server, it is now possible to efficiently detect files that have not changed since the last backup snapshot. When possible, unchanged files are not processed, which can make file-based backups complete faster.
This version is based on Debian 12.8 (“Bookworm”), but uses the newer Linux kernel 6.8.12-4 as stable default and kernel 6.11 as opt-in. The backup platform comes with ZFS 2.2.6 (with compatibility patches for Kernel 6.11).

Proxmox Virtual Environment 8.3 released

2024-11-21T14:10:47+01:00

VIENNA, Austria – November 21, 2024 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") has today released version 8.3 of its virtualization platform, Proxmox Virtual Environment. The enterprise virtualization solution features essential management tools and a user-friendly web interface, allowing organizations of all sizes, sectors and industries, to deploy open-source solutions in clustered, highly available setups. The world-wide customer base uses it to deploy extensive infrastructures across vast geographical locations, and integrate multiple applications seamlessly.

This version is based on Debian 12.8 (Bookworm), but uses the Linux kernel 6.8.12-4 as stable default, and allows for opt-in use of kernel 6.11. The software includes updates to the latest versions of leading open-source technologies for virtual environments like QEMU 9.0.2, LXC 6.0.0 , and ZFS 2.2.6 (with compatibility patches for Kernel 6.11).

Enhancements in Proxmox Virtual Environment 8.3

Alignment of the Software-Defined Networking (SDN) stack with the firewall: The SDN technology allows users to create virtual zones and networks (VNets), enabling them to effectively manage and control complex networking configurations and multitenancy setups via the web interface of Proxmox VE. The SDN stack is now more closely integrated with the firewall, with the ability to automatically generate IP sets for VNets and virtual guests managed by the IP address management plugin. Referencing IP sets in the firewall rules simplifies their creation and maintenance. In addition, the opt-in firewall based on nftables now has the capability to filter forwarded network traffic at the host and at the virtual network (VNet) level. For example, this can be used to restrict SNAT traffic or traffic flowing from one Simple Zone to another.
Webhook target for the notification system: The flexible notification system in Proxmox solutions uses a matcher-based approach to route notifications to various target types, allowing for granular control over when, where, and how notifications are sent. The new webhook notification target enables users to trigger HTTP requests for events like system updates, cluster node issues, or backup job. It supports customizable request headers and body content, allowing for seamless integration with any webhook-compatible service.
A new ‘Tag View’ functionality for the resource tree offers users a rapid and customizable overview of the virtual guests: The new ‘Tag View’ allows users to view their virtual guests grouped according to the assigned tags.
Support for Ceph Squid (technology preview): Proxmox Virtual Environment 8.3 adds support for Ceph Squid 19.2.0 and continues to support Ceph Reef 18.2.4 and Ceph Quincy 17.2.7. The preferred Ceph version can be selected during the installation process.
Faster container backups: When backing up containers to Proxmox Backup Server, it is now possible to efficiently detect files that have not changed since the last backup snapshot. When possible, unchanged files are not processed, which can make container backups complete faster.
Migration from other hypervisors: The Proxmox developers have streamlined the guest import from files in Open Virtualization Format (OVF) and Open Virtualization Appliances (OVA). Proxmox VE now allows users to import OVF and OVA files directly from file-based storage via the web interface. This simplifies the guest import process and allows users to either upload OVA files from a local machine or download them from a URL. Additionally, Proxmox VE also offers an import wizard facilitating the migration of VMs from other hypervisors, such as VMware guests.

Citation CTO Thomas Lamprecht:

"Our virtualization platform is designed to empower enterprises with unparalleled efficiency and control," said Thomas Lamprecht, CTO of Proxmox. "By integrating advanced Software-Defined Networking capabilities, we’re enabling businesses to simplify their IT infrastructure, improve agility, and drive scalable growth. We are currently developing the inaugural version of the Proxmox Datacenter Manager, which will provide a unified management interface for multi-datacenter operations and facilitate the effective management of multiple clusters across diverse data centers.”

Citation COO Tim Marx:

"The open-source project Proxmox VE has experienced significant growth over the past few months, adding 300,000 active hosts, bringing the total to around 1.3 million. In the current dynamic business environment, we are well-positioned for growth, particularly as recent pricing shifts in the market create new opportunities for us to serve our customers more effectively," said Tim Marx, COO of Proxmox. "Our commitment to quality and value has resonated strongly, and we’re excited to continue building on this momentum."

Proxmox Backup Server 3.2 released

2024-04-25T13:43:28+02:00

VIENNA, Austria – April 25, 2024 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") today announced version 3.2 of its open-source server backup solution. The enterprise solution for backing up and restoring VMs, containers, and physical hosts supports incremental backups, deduplication, Zstandard compression, and authenticated encryption.

Enhancements in Proxmox Backup Server 3.2

Notification system: This release introduces a new framework that uses a matcher-based approach to route notifications. It allows users define specific target types as recipients of notifications. Alongside the current local Postfix MTA, supported targets include Gotify servers or remote SMTP servers optionally with SMTP authentication. Notification matchers determine which targets will get notifications for particular events based on predetermined rules. The notification system offers greater flexibility, and precision for defining when, where, and how notifications are sent.
Automated and unattended installation: Proxmox offers a new ‘proxmox-auto-install-assistant’ tool that fully automates the setup process on bare-metal. Automated installation allows for the rapid deployment of Proxmox Backup hosts without the need for manual access to the systems, saving time and reducing the risk of errors. To use this method, an answer file must be prepared with the necessary configuration settings for the installation process. This file can be provided directly in the ISO, on an additional disk such as a USB flash drive, or over the network. Automated installation is useful in various scenarios, such as deploying large-scale infrastructure, automating the setup process, and ensuring consistent configurations across multiple systems.
Exclude backup groups from jobs: Group filters for sync jobs and for tape backup jobs can now exclude particular backup groups. In order to decide whether a job should process a particular backup group, „include“ filters are processed before the „exclude“ filters.
Overview of prune and garbage collection jobs: A new tab in the “Datastore” summary panel shows defined prune and garbage collection jobs for all datastores. This allows to quickly assess whether all datastores are correctly set up to regularly run important maintenance tasks. It also offers more flexibility in adjusting the times and avoiding the simultaneous execution of two or more garbage collection jobs, which could lead to unwanted hardware utilization overload.

Proxmox Backup Server seamlessly integrates into Proxmox Virtual Environment – users just need to add the storage for the Proxmox Backup Server as a new storage backup target to Proxmox VE.

Proxmox Virtual Environment 8.2 with Import Wizard released

2024-04-22T18:49:01+02:00

VIENNA, Austria – April 24, 2024 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") has today released version 8.2 of its server virtualization management platform, Proxmox Virtual Environment. The new version is based on Debian 12.5 (Bookworm), but using a newer Linux kernel 6.8, and includes updates to the latest versions of leading open-source technologies for virtual environments like QEMU 8.1, LXC 6.0, Ceph 18.2, and ZFS 2.2.

Proxmox Virtual Environment 8.2 comes with an import wizard to migrate VMware ESXi guests to Proxmox VE, with a new tool for automated installation from the ISO to bare-metal servers, a backup fleecing feature implementation to decouple slower backup storage from the VM performance, and several UI improvements.

Highlights in Proxmox Virtual Environment 8.2

Import Wizard for VMware ESXi VMs: Proxmox VE provides an integrated VM importer presented as storage plugin for native integration into the API and web-based user interface. It offers users the ability to import guests directly from other hypervisors. Currently, it allows to import VMware-based VMs (ESXi and vCenter). You can use this to import the VM as a whole, with most of the original configuration settings mapped to Proxmox VE's configuration model.
Automated and Unattended Installation: Proxmox offers a new ‘proxmox-auto-install-assistant’ tool that fully automates the setup process on bare-metal. Automated installation allows for the rapid deployment of Proxmox VE hosts without the need for manual access to the systems, saving time and reducing the risk of errors. To use this method, an answer file must be prepared with the necessary configuration settings for the installation process. This file can be provided directly in the ISO, on an additional disk such as a USB flash drive, or over the network. Automated installation is useful in various scenarios, such as deploying large-scale infrastructure, automating the setup process, and ensuring consistent configurations across multiple systems.
Backup Fleecing: When creating a backup of a running VM, a slow backup target can negatively impact guest IO performance during the backup process. Fleecing can reduce this impact by caching data blocks in a fleecing image rather than sending it directly to the backup target, which can help guest IO performance and even prevent hangs at the cost of requiring more storage space. Backup fleecing is especially beneficial when backing up IO-heavy guests to a remote Proxmox Backup Server or other backup storage with a slow network connection.
Firewall modernization with nftables (technology preview): Proxmox VE comes with a new firewall implementation that uses nftables instead of iptables. The opt-in feature in tech preview is written in the Rust programming language. Although the new implementation is close to feature parity with the existing one, the nftables firewall must be enabled manually and remains a preview to first gather feedback from the community.

Further enhancements

Device passthrough for containers via GUI: While the API and CLI have supported LXC device passthrough since version 8.1, GUI configuration is now possible as well.
Advanced backup settings: Backup jobs come with new advanced settings, including performance settings and bandwidth limits.
Custom ACME directories/providers: This release now supports custom ACME-enabled Certificate Authorities (CA) with optional External Account Binding (EAB) authentication.
Multiple enhancements in the GUI: Disabling the double-click editing option in the notes field makes it easier to select and copy text without accidentally opening the editor. On edit screens, the reset button is now in a new location reducing the risk of accidental clicks.

Availability

Proxmox VE 8.2 is available for download at https://www.proxmox.com/downloads. The ISO contains the complete feature-set and can be installed on bare-metal.

License: Proxmox Virtual Environment is free and open-source software, published under the GNU Affero General Public License, v3.

Proxmox Mail Gateway 8.1 with enhanced Rule System

2024-02-27T16:35:18+01:00

VIENNA, Austria – February 29, 2024 – Enterprise software developer Proxmox Server Solutions GmbH ("Proxmox" or the "Company") has today released Proxmox Mail Gateway 8.1, the latest version of its open-source email security solution. The Mail Gateway platform is a complete operating system based on Debian 12.5, but defaulting to a newer Linux kernel 6.5, and including ZFS 2.2.2 and PostgreSQL 15.6.

The anti-spam and anti-virus filtering solution functions as a full featured mail proxy, that is deployed between the firewall and the internal mail server. It protects organizations against threats, such as spam, viruses, Trojans, and phishing emails.

What's new in Proxmox Mail Gateway 8.1

Enhanced rule system: Proxmox Mail Gateway is known for its comprehensive object-oriented rule system, where the mail flow can be controlled and filtered. Improvements in this version now allow the selection of a “match-if” mode for entries in What/Who/When objects, and multiple objects in rules, providing flexible control over whether All, Any, Some but not all, or None must match.
DKIM signing: Optionally, DKIM signing can now select the signing domain based on header information instead of the envelope information. This allows for the configuration of more stringent DMARC policies in certain environments.
Support for secure boot: Like the Proxmox virtualization and backup solutions, this version 8.1 is now compatible with Secure Boot. With this security feature, the boot process of a computer can be protected by ensuring that only software with a valid digital signature launches on a machine. Proxmox Mail Gateway now includes a signed shim bootloader trusted by most hardware's UEFI implementations. This allows installing it in environments where Secure Boot is required and enabled. The documentation explains how an existing Proxmox Mail Gateway installation can be switched over to Secure Boot without reinstallation.
Management via web interface: A new filter- and search box added to the web interface simplifies the management of large deployments. Filtering is now possible in Relay Domains, Transport, Networks, and for Objects in the rule system. Additionally, Croatian and Georgian translations have been added, and translations for other languages have been improved.

Further notable enhancements

Proxmox ships its own heavily tweaked kernel which all products share. For the Mail Gateway, this is now also reflected in the renaming from pve-kernel and pve-headers to proxmox-kernel and proxmox-headers respectively in all relevant packages. The new proxmox-default-kernel and proxmox-default-headers meta-packages will depend on the currently recommended kernel-series.
SMTP smuggling mitigation: With a prompt response to the spoofing attack at SMTP protocol level at the end of 2023, the Postfix configuration was secured as quickly as possible against SMTP smuggling in line with the latest recommendations from upstream. Proxmox Mail Gateway users who have not yet updated are encouraged to do so and verify that they have not missed the template change.
Fixed: Restoring a Mail Gateway backup from a cluster with statistics, does not interfere with creating a fresh cluster on the restored node.
The Log Tracker tool, which powers the Tracking Center, now uses UTC by default for internal time calculations, eliminating problems with time zone changes such as switching from Standard Time to Daylight Saving Time and vice versa.

Availability

For enterprise use, Proxmox Server Solutions GmbH offers a subscription service that provides access at all levels to the extensively tested, stable Enterprise Repository. This repository provides regular updates via the web interface and is recommended for production use. At the Basic and higher subscription levels, technical support from the Proxmox team is also available. Subscription pricing starts at EUR 175 per host per year for unlimited users and domains.

When restoring a single snapshot, the Proxmox Backup solution now shows a list of the required tapes. When restoring backups, the task does not abort the job if a tape is missing in the changer but waits for the correct tape to be inserted.
Flexible synchronisation: On the client side, a “transfer-last” parameter for sync jobs is now supported. This provides more flexibility by making it possible to specify the number of most recent backups to be transferred.
Secure lockout for TFA/TOTP: To further improve security, user accounts with repeatedly failed login attempts—failing the second factor authentication—are locked out. This protects against attacks where the user password is obtained and a brute-force guess is attempted on the second factor. With a recovery key, or manually by an administrator, the user account can be unlocked again.
Text-based user interface (TUI) for the installer ISO: A text-based user interface has been added and can now be used optionally to gather all required information. This addresses potential issues when launching the GTK-based graphical installer on very new and rather old hardware.

The enterprise backup solution, capable of backing up and restoring VMs, containers, and physical hosts, supports incremental, fully deduplicated backups, significantly reducing network load, required storage space and, as a result, total cost of infrastructure. With the integrated web interface, users can easily manage and monitor all backup tasks from a single pane of glass and quickly recover single files, entire VMs, and archives in case of a disaster.

Proxmox Backup Server seamlessly integrates into Proxmox Virtual Environment—users just need to add the storage for the Proxmox Backup Server as a new storage backup target to Proxmox VE.

Proxmox Virtual Environment 8.0 with Debian 12 "Bookworm" released

2023-07-10T14:56:02+02:00

VIENNA, Austria – June 22, 2023 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") today released the stable version 8.0 of its server virtualization management platform Proxmox Virtual Environment. This major release is based on the latest Debian 12 (“Bookworm), and comes with an extensively tested and detailed upgrade path for users of Proxmox VE 7.4 or older versions to enable a smooth upgrade. Proxmox VE 8.0 uses a newer Linux kernel 6.2 as stable default, and includes updates to the latest versions of leading open-source technologies for virtual environments like QEMU 8.0.2, LXC 5.0.2, ZFS 2.1.12, and Ceph Quincy 17.2.6.

The virtualization platform from Proxmox comes stocked with all the essential management tools and an easy-to-use, web-based user interface. This allows to conveniently manage individual hosts or the entire data center with out-of-the-box tools - either via a web browser or the command line.

Further highlights in Proxmox Virtual Environment 8.0

New Ceph Enterprise repository: Proxmox Virtual Environment fully integrates Ceph Quincy, allowing to run and manage Ceph storage directly from any of the cluster nodes and to easily setup and manage a hyper-converged infrastructure. The Ceph source code is packaged by the Proxmox development team and—after extensive tests—delivered in the stable Enterprise repository. This unifies the delivery of Ceph with other components of Proxmox VE. With version 8.0, all Proxmox customers with an active subscription can now access the stable Ceph Enterprise repository recommended for production environments.
Authentication realm sync jobs: The synchronization of users and groups for LDAP-based realms (LDAP & Microsoft Active Directory), can now be configured to run automatically at regular intervals. This simplifies management, and removes a source for configuration errors and omissions compared to synchronizing the realm manually.
Network resources defined for Software-defined Networking (SDN) are now also available as objects in the access control subsystem (ACL) of Proxmox VE. It is possible to grant fine-grained permissions for host network bridges and VNets to specific users and groups.
Resource mappings: Mappings between resources, such as PCI(e) or USB devices, and nodes in a Proxmox VE cluster, can now be created and managed in the API and the web interface. VM guests can get such an abstract resource assigned, which can be matched with concrete resources on each node. This enables offline migrations for VMs with passed-through devices. The mappings are also represented in the ACL system of Proxmox VE, allowing a user to be granted access to one or more specific devices, without requiring root access. In case a conflicting entry is detected, e.g. due to address changes or overlaps, users are informed on VM start.
Secure lockout for Two-factor authentication/TOTP: To further improve security, user accounts with too many login attempts - failing the second factor authentication - are locked out. This protects against attacks where the user password is obtained and a brute-force guess is attempted on the second factor. If TFA fails too many times in a row, the user account is locked out for one hour. If TOTP failed too many times in a row, TOTP is disabled for the user account. The user account can be unlocked again with a recovery key, or manually by an administrator.
Text-based user interface (TUI) for the installer ISO: A text-based user interface has been added and can now be used optionally to gather all required information. This eliminates issues when launching the GTK-based graphical installer that sometimes occur on very new as well as rather old hardware.
The x86-64-v2-AES model is the new default CPU type for VMs created via the web interface. It provides important extra features over the qemu64/kvm64, and improves performance of many computing operations.

Availability

Proxmox Virtual Environment is free and open-source software, published under the GNU Affero General Public License, v3. The ISO contains the complete feature-set and can be installed on bare-metal. Proxmox VE 8.0 is available for download at https://www.proxmox.com/downloads

Seamless upgrade instructions from Proxmox VE 7.x to 8.x are available.
It’s also possible to install Proxmox VE 8 on top of Debian.

Proxmox Backup Server 2.4 available

2023-03-29T11:09:10+02:00

VIENNA, Austria – March 29, 2023 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") has today released version 2.4 of Proxmox Backup Server bringing dark mode for the web interface, LDAP authentication realm, and support for WORM tapes. The open-source server backup solution allows backing up and restoring VMs, containers, and physical hosts. By supporting incremental, fully deduplicated backups, it significantly reduces network load, required storage space and, as a result, total infrastructure cost. With the integrated web interface, users can easily manage and monitor all backup tasks from a single pane of glass and quickly recover single files, entire VMs, and archives in case of a disaster.

What’s new in Proxmox Backup Server 2.4

This version is based on Debian 11.6 “Bullseye”, but using a newer Linux kernel 5.15, and including ZFS 2.1.9. While the 5.15 kernel is the stable default, Linux kernel 6.2 can optionally be installed for better support of the latest hardware.

Dark Mode: The fully integrated theme “Proxmox Dark” is available for the web interface. By default, the prefers-color-scheme media query from the browser or operating system will be used to decide the default color scheme. Users can override the theme via a newly added Color Theme selector in the user menu.
Added LDAP authentication realm and user synchronization: This version now allows user authentication against an external LDAP server. In order to be able to log in, users in LDAP realms must be added manually. Alternatively, users can be synced automatically from the LDAP server. In the web interface the dialog Add User has a realm field, making it possible to manually add users to an LDAP or OpenID Connect realm.
WORM tapes: Initial support for WORM (write once, read many) tapes is available with version 2.4. With the special WORM cartridges, data can only be written to the memory once; subsequent changes are not possible. WORM compliant storage is often a requirement for organizations with legal regulations. In addition, it serves, for example, to protect against the accidental or intentional deletion of critical data. Proxmox Backup Server makes no distinction between normal and WORM tapes, so different naming schemes and dedicated media pools are recommended.

Further notable enhancements

Task logs can now be downloaded directly in the web interface as text files for further inspection.
Installation ISO: During installation, the UTC timezone can be selected, facilitating the synchronization of hosts or clusters that are distributed across multiple geographic locations.
The technical documentation has been further improved with more detailed explanations of the Garbage Collection (GC). Also, dark mode support for the docs and the API viewer widget has been added.

Availability

Proxmox Backup Server is free and open-source software, published under the GNU AGPL, v3. The downloadable ISO image can be quickly installed on bare-metal using the installation wizard. The centrally managed software stack Proxmox Backup Server 2.4 is now available for download at https://www.proxmox.com/downloads Distribution upgrades from older versions of Proxmox Backup Server are possible via APT. It is also possible to install Proxmox Backup Server on top of Debian.

VIENNA, Austria – March 28, 2023 – Enterprise software developer Proxmox Server Solutions GmbH ("Proxmox") today has released Proxmox Mail Gateway 7.3, the latest version of its open-source email security solution. The anti-spam and anti-virus filtering solution functions as a full featured mail proxy, is deployed between the firewall and the internal mail server. It protects organizations against threats, such as spam, viruses, Trojans, and phishing emails.

What’s new in Proxmox Mail Gateway 7.3

Proxmox Mail Gateway is a complete operating system based on Debian 11.6 (“Bullseye”), but using a newer Linux kernel 5.15, and including ZFS 2.1.9 and PostgreSQL 13.10. While the 5.15 kernel is the stable default, Linux kernel 6.2 can optionally be installed for better support of the latest hardware.
With this version, the Proxmox developers integrate the new major version 4.0.0 of Apache SpamAssassin. It is now possible to detect spam inside of attachments. The detection is implemented for the file types .pdf, .odt, .docx, .doc, .rtf, as well as images (through OCR). Additionally, there is improved support for using information from the Domain-based Message Authentication, Reporting and Conformance (DMARC) policy, for more in-depth analysis. In general, all SpamAssassin configuration files shipped with the pmg-api package were adapted to the new SpamAssassin features.
TLS-policy improvements: Proxmox Mail Gateway now can enforce TLS encryption for inbound mail.
The SMTPUTF8 support has been improved and can now be disabled through the API or GUI.
Dark theme: Like other Proxmox solutions, the Mail Gateway now brings a fully-integrated "Proxmox Dark" theme for the web interface. To detect if a user has requested light or dark color themes, the CSS media feature prefers-color-scheme is used. Through settings in the operating system or their browser, users can indicate their preferences. However, users can switch between the color schemes manually in the web interface as well. Furthermore, the documentation as well as the Proxmox Mail Gateway API Viewer now have a dark mode.
Task logs can now be downloaded directly as text files for further inspection.

Proxmox Virtual Environment 7.4 released

2023-03-23T11:09:10+01:00

VIENNA, Austria – March 23, 2023 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") released version 7.4 of its server virtualization management platform, Proxmox Virtual Environment, today. The new version includes a focus on improved usability, bringing even more management tasks to the web interface.

Highlights in Proxmox Virtual Environment 7.4

Proxmox VE 7.4 is based on Debian 11.6 (“Bullseye”), but uses a newer, long-term supported Linux kernel 5.15 and includes updates to the latest versions of leading open-source technologies for virtual environments, such as QEMU 7.2, LXC 5.0.2, and ZFS 2.1.9. The platform supports Ceph Quincy 17.2.5 as default for new installations or optionally Ceph Pacific 16.2.11.
By default, Proxmox VE uses a newer, long-term supported Linux kernel 5.15. Optionally, Linux kernel 6.2 can be installed, providing support for the current features of the latest hardware. The kernel can be installed via the shell by selecting the pve-kernel-6.2 meta package. After a reboot, the new kernel will be activated.
Dark theme: A fully-integrated "Proxmox Dark" theme variant is now available for the web interface and the lovers of darkness. The theme is based on the Crisp light theme. To detect if a user has requested light or dark color themes, the CSS media feature prefers-color-scheme is used. Through settings in the operating system or their browser, users can indicate their preferences. However, users can switch between the color schemes manually in the web interface as well.
Ceph OSD: The web interface and the API now display detailed OSD information. This reduces work for administrators, as they no longer have to gather the necessary information from various places.
Task logs can be downloaded as text files in the GUI, which helps to make further inspection easier.
Sorting of the resource tree: VMs or containers can now be sorted by their names or by VMID, by selecting the appropriate sort-order. Especially in large clusters, sorting all guests by name can provide a better overview for users who rely on them.
HA Manager: By adding a CRM command, an online node can be switched manually into maintenance (without reboot). Also, the support for the HA Cluster Resource Scheduler (CRS) stack was extended and can now rebalance VMs & containers automatically on start, not only on recovery.

Further notable enhancements

To avoid the browser error "Connection reset", HTTP requests are automatically redirected to HTTPS. This can prevent confusion, especially after setting up a Proxmox VE host for the first time.
When users select the storage view for a Proxmox Backup Server storage, they can then use the columns for encryption and verification status for sorting.
Containers: The open-source architectures riscv32 and riscv64 can be used for LXC containers. Additionally, some container templates for amd64 were updated to newer upstream versions.
Virtual guests: Renaming the "Bulk Stop" action to "Bulk Shutdown" reflects the actual behavior of this action.
HA Manager: In preparation for the dynamic load scheduling in clusters, the high availability manager abstracts and unifies the needed resources (CPU, memory) of the different HA services (containers, VMs).
Improved management for Proxmox VE clusters: the Proxmox Offline Mirror tool now supports using HTTP proxies for fetching updates.
Storage: With the help of the option content-dirs, the specific subdirectories for content-types—for example isos, container templates, backups, guest disks—can be overridden with custom values.
Access Control: By refactoring the ACL computation, performance significantly improved—up to a factor of 450—in setups with many entries and huge user bases or with many access control rules.
Notifications for new package updates can optionally be disabled, further improving the administration experience .
Installation ISO: During installation, the UTC timezone can be selected, facilitating the synchronization of hosts or clusters that are distributed across multiple geographic locations.
Localization (i18n): Translations for Arabic, French, German, Italian, Japanese, Russian, Slovenian, and Traditional Chinese were improved.

VIENNA, Austria – November 30, 2022 – Enterprise software developer Proxmox Server Solutions, the company behind Proxmox Mail Gateway, announces today point release 7.2 of its open-source email security solution. Proxmox Mail Gateway, available since 2005, is one of few enterprise-grade open-source email filtering solutions. It protects organizations against threats such as spam, viruses, Trojans, and phishing emails and functions as a fully-featured mail proxy that is deployed between the firewall and the internal mail server.

Enhancements in Proxmox Mail Gateway 7.2

Proxmox Mail Gateway 7.2 is a complete operating system based on Debian 11.5 (“Bullseye”), using the newer Linux kernel 5.15, as well as ZFS 2.1.6. The Proxmox developers ship the latest upstream release of Apache SpamAssassin 3.4.6 with an updated rule-set for its Mail Gateway. PostgreSQL 13.8 is also included.
Enhancements in the rule system: With the comprehensive object-oriented rule system of Proxmox Mail Gateway, users can create customized rules for their mail environment. This version improves the handling of international emails by adding support for Unicode characters and better handles SMTPUTF8 emails.
The Quarantine interface brings improved usability for administrators and end-users alike:
- In the administrator view, the admin can now select multiple emails, the ‘Receiver’ information is displayed, and there is a context menu in the mail-listing, for the ‘Attachment’ and ‘Virus’ quarantines.
- The SpamAssassin rules can now be visually sorted by scores in the SpamInfo grid, thus helping to accelerate the decision on which ones to select and remove. The 'Deliver' and 'Delete' actions are now colorized, improving intuitive handling of common actions.
- By additionally displaying attachments in the ‘Spam’ and ‘Virus’ quarantine, administrators get a more complete overview of the email in question.
- ‘Virus’ and ‘Attachment’ quarantine can now optionally be filtered by ‘Receiver’ – a function especially helpful in larger deployments.
- The Proxmox Offline Mirror tool allows keeping Proxmox Mail Gateway nodes – with restricted or without access to the public internet – up-to-date and running. With the ‘proxmox-offline-mirror’ utility, it is possible to manage a local apt mirror for all package updates for Proxmox and Debian projects. From that mirror, users can create an external medium (USB flash drive or a local network share) and can then update their policy-restricted or air-gapped systems. For subscribers with a Premium or Standard subscription level, Proxmox offers an offline subscription key for its product portfolio.

Proxmox Backup Server 2.3 available

2022-11-10T17:50:33+01:00

VIENNA, Austria – November 29, 2022 – Enterprise software developer Proxmox Server Solutions (henceforth "Proxmox"), the company behind Proxmox Backup Server announces enhancements to its open-source server backup solution, which are now generally available. The enterprise solution for backing up and restoring VMs, containers, and physical hosts supports incremental backups, deduplication, Zstandard compression, and authenticated encryption. This version brings enhancements for the web interface, tape backup, as well as countless general client and backend improvements.

Highlights in Proxmox Backup Server 2.3

Proxmox Backup Server is based on Debian 11.5 (“Bullseye”), uses the newer Linux kernel 5.15 as stable default and kernel 5.19 as opt-in, and includes ZFS 2.1.6. Features such as fine-grained access control, data integrity verification, and the possibility to create off-site backups through remote sync and tape backups help planning a ransomware defense strategy and ensure that critical data stays protected.
Pruning namespaces: Pruning lets you specify which backup snapshots you want to keep, in a systematic manner. With this version, the prune job system has been expanded to take namespaces into account: Up until now it has only been possible to add a single-schedule per datastore; now pruning can also be limited to certain namespaces. With the built-in prune simulator users can explore the effect of different retention options with various backup schedules. Namespaces in Proxmox Backup Server (introduced in version 2.2) help organize backups from multiple sites (local and remote) hierarchically, while keeping the required storage space minimal through deduplication. With the new fine-grained control in Proxmox Backup Server 2.3, businesses can determine when and how deeply a particular namespace is pruned.
Support for sending metrics to InfluxDB: Version 2.3 of Proxmox Backup Server can gather and send critical stats, relevant for measuring performance, to InfluxDB, an open-source database management system for time series. Such metrics are, for example, CPU load averages and IOwait percentages, NIC traffic statistics, filesystem usage or IO for datastores.
Tape backup improvements: The inventory command, which can be used for disaster recovery, can now optionally restore the catalogs of backups stored on tape, potentially saving critical time in a worst case scenario.
Proxmox Offline Mirror: The Proxmox Offline Mirror tool allows to keep the Proxmox Backup Server nodes – with restricted or without access to the public internet – up-to-date and running. With the ‘proxmox-offline-mirror’ utility it’s possible to manage a local APT mirror for all package updates for Proxmox and Debian projects. From that mirror, users can create an external medium (USB flash drive or a local network share), and can then update their policy-restricted or air-gapped systems. For subscribers with a Premium or Standard subscription level, Proxmox offers an offline subscription key for its product portfolio.

The whole software stack of Proxmox Backup Server is written in Rust – a modern, fast, and memory-efficient language. Currently, the backup solution seamlessly integrates into Proxmox Virtual Environment – users just need to add the storage for the Proxmox Backup Server as a new storage backup target to the virtualization platform.

Availability

Distribution upgrades from older versions of Proxmox Backup Server are possible via APT. It is also possible to install Proxmox Backup Server on top of Debian.

For enterprise users, Proxmox Server Solutions GmbH offers a subscription-based support model, which provides access to the extensively tested Enterprise Repository, with regular updates via the web interface, as well as technical support on a subscription basis. Prices start at EUR 449 per server, including unlimited backup storage and unlimited backup-clients.

Proxmox introduces Cluster Resource Scheduler for Proxmox Virtual Environment 7.3

2022-11-10T17:46:03+01:00

VIENNA, Austria – November 22, 2022 – Enterprise software developer Proxmox Server Solutions (henceforth "Proxmox"), the company behind Proxmox Virtual Environment (VE) today announced enhancements to its server virtualization management platform, now generally available. Users can seamlessly deploy virtual machines and containers, software-defined storage, and networking on a single platform. The new point release Proxmox VE 7.3 is based on Debian 11.5 (“Bullseye”), but using a newer Linux kernel 5.15, and includes updates to the latest versions of leading open-source technologies for virtual environments like QEMU 7.1, LXC 5.0.0, and ZFS 2.1.6. The virtualization platform supports Ceph Quincy 17.2.5 as default for new installations, and optionally Ceph Pacific 16.2.10.

Proxmox Virtual Environment 7.3 comes with initial support for Cluster Resource Scheduling, enables updates for air-gapped systems with the new Proxmox Offline Mirror tool, and has improved UX for various management tasks, as well as interesting storage technologies like ZFS dRAID.

Highlights in Proxmox Virtual Environment 7.3

Technology preview: Initial support for a Cluster Resource Scheduler (CRS): In cases when the Proxmox HA Manager needs to find a new host node for a HA service (e.g. recovery, shutdown-policy, HA group configuration changes), it previously used to only count the number of active HA services for load balancing. This version integrates the TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) method, a multi-criteria decision making analysis, for finding the best alternative target node.

When the new scheduler mode "Static Load" is applied, the TOPSIS tool uses the "total memory" and "vCPU" properties of the HA resource to guide the decision on which node in the cluster a HA resource is started on. With this CRS foundation established, the Proxmox developers plan to extend it in future releases with a dynamic load scheduler and live load balancing.

Proxmox Offline Mirror: The Proxmox Offline Mirror tool allows to keep Proxmox VE nodes – with restricted or without access to the public internet – up-to-date and running. With the ‘proxmox-offline-mirror’ utility it’s possible to manage a local apt mirror for all package updates for Proxmox and Debian projects. From that mirror, users can create an external medium (USB flash drive or a local network share), and can then update their policy-restricted or air-gapped systems. For subscribers with a Premium and Standard subscription level, Proxmox offers an offline subscription key for its product portfolio.

Support for Ceph Quincy and Ceph Pacific: Proxmox Virtual Environment 7.3 supports Ceph Quincy 17.2.5 as default and Ceph Pacific 16.2.10. The preferred Ceph version can be selected during the installation process. The Proxmox developers have added heuristical checks to see if it is safe to stop or remove a service instance (MON, MDS, OSD). If removing or stopping a service would affect the cluster operation, the web interface will now alert users with a warning. Overall, the usability for creating new clusters, including selecting the network and checking duplicate IP, has been improved.

Tags for virtual guests: With the option of tagging virtual guests in the web interface, administrators can gain even better overview and simplify management tasks, for example by differentiating between ‘production’ and ‘testing’ VMs. Tags can either be user-modifiable, or restricted to higher-privileged administrator accounts. Tagging has been already available in the configuration (CLI, API), providing users with a possibility for automatization.

Further notable enhancements

ZFS dRAID pools: This version comes with support for creating ZFS dRAID pools in the web interface. Declustered RAID (dRAID) – a feature added in OpenZFS 2.1.0 – is a software raid implementation improving disk recovery time in large storage arrays. If a disk drive fails, the hot spare drive(s) participating in the RAID are used for rebuilding. As its layout is more complex than RAIDz, dRAID is an option for large storage arrays.
Virtual Machines:
- CPU pinning: With the taskset command, a VM can be bind to a certain or a range of CPU core(s). CPU affinity can help optimize cache performance, for example in multiprocessing computers.
- USB devices have been reworked and can now be hot-plugged; also it’s possible to pass through up to 14 USB devices (previous: five) to a virtual machine.
Proxmox VE Mobile App: The Proxmox VE Android app is based on Flutter 3.0, and allows users to access the Proxmox VE server(s), and manage cluster, nodes, VMs, and containers. The app now supports and targets Android 13. Also feedback about running backup tasks is available.

Availability

The virtualization stack from Proxmox comes stocked with all the essential management tools, as well as an easy-to-use, web-based user interface. This allows for simple, out-of-the-box management of the host, either through the command line or a standard web browser.

Proxmox enables Namespaces in Proxmox Backup Server 2.2

2022-05-07T12:45:58+02:00

Updates include a new namespace feature for efficient backup management, maintenance modes with operations tracking, optimized file restore, and general performance improvements.

VIENNA, Austria – May 18, 2022 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") today announced the latest update to its open-source backup solution Proxmox Backup Server, which makes it easy to back up and restore virtual machines, containers, and physical hosts. The new version 2.2 is based on Debian 11.3 “Bullseye”, but using the newer Linux kernel 5.15, and including ZFS 2.1.4.

The enterprise backup solution from Proxmox supports incremental, fully deduplicated backups, significantly reducing network load, required storage space and, as a result, total cost of infrastructure. Featuring strong client-side encryption, Proxmox Backup Server allows businesses to back up data to targets which are not fully trusted, in a space-efficient manner and restore VMs, archives or single objects in a flash. New features and capabilities in Proxmox Backup Server 2.2 further ensure that data is reliably backed up and restored, efficiently organized, and easily managed.

What’s new in Proxmox Backup Server 2.2

“Namespace” feature to significantly improve backup management of multiple sources on-premises, remotely, and in the cloud: Proxmox Backup Server stores backup data (that is: backup snapshots and their referenced chunks) in datastores, and multiple datastores can be configured. The deduplication of data, which helps improve storage utilization, is based on reusing chunks, which are referenced by the indexes in a backup snapshot. This means that multiple indexes can reference the same chunks (even across backup snapshots), reducing the amount of space needed to contain the data.

To help neatly organize backups and minimize the required storage space, Proxmox Backup Server 2.2 introduces namespaces. Backups from multiple sites (local and remote) or Proxmox VE setups can now be organized into namespaces within a single datastore. This allows for optimal use of deduplication, as this technique is only applied at the datastore level, and reduces the maintenance burden of managing multiple datastores.

With namespaces, businesses can safely back up from different sources to one (physical) datastore, with more fine-grained access control and without having naming conflicts. The "namespace" feature allows sharing a single datastore, including the chunk store, across multiple backup ID namespaces (e.g., one per Proxmox VE cluster).

Maintenance Mode with Active Operations Tracking: To enable administrators to safely execute maintenance tasks on a datastore, the newly implemented “read-only” and “offline” maintenance modes were added. Additionally, by tracking active operations, Proxmox Backup Server can check for currently conflicting access operations, for example a previously started backup restore task, and await their completion before entering maintenance mode, while simultaneously blocking new incoming operations.

Performance and Back-End Improvements: General improvements in the back-end help to drastically reduce memory usage during backup. By extensively analyzing the behavior of the system allocator, and then optimizing the interaction between the allocator and Proxmox Backup Server, for example, the memory footprint has been reduced significantly.
Additionally, with version 2.2, it is now possible to do a dry-run of a desired backup via the command line, to view what will happen.

Improved File Restore: To confidently restore data and get back to business quickly, this version includes enhanced file restore. Proxmox Backup Server adds support for downloading Zstandard-compressed tar archives. Compared to the already included zip format, tar archives support more file types (for example, hard links and device nodes), and zstd allows for fast and efficient compression.
To improve the handling of non-ASCII code point extraction under Windows, the language encoding flag is added to files when creating a zip archive, if the entry is valid UTF-8. Additionally, ZFS pools get mounted only on demand, and the automatic pre-mounting of ZFS pools is avoided to prevent the upfront time-cost.

New GUI enhancements greatly improve productivity: With the included web interface, backup administrators can effectively reduce work hours. To simplify management, this version now brings the ‘group-filter’ to the GUI. The "Add" and "Edit" windows of the sync jobs and tape-backup jobs panels have an added tab for the filter option. Users can specify in the GUI if they want to process only a specific backup type (ct, vm, host), a specific group, or a regex that matches the group-ID for such a job. The node configuration file now supports multi-line comments and has a Markdown-aware panel for recording structured notes. Some translations have been updated including Arabic, French, German, Japanese, Polish, and Turkish.

"Our customers and partners are looking for efficient ways to protect their business data, while keeping the maintenance burden low. With Proxmox Backup Server 2.2, we make this even easier by adding namespaces and lowering overhead."
Thomas Lamprecht - Lead developer at Proxmox

Proxmox Backup Server is designed as a standalone solution, thus avoiding vendor lock-in. The client-server backup solution enables secure backup and restore of critical business data and is currently optimized for the open-source virtualization management platform Proxmox Virtual Environment, the company’s flagship product. Users simply need to add the Proxmox Backup Server datastore as a new backup storage target to Proxmox VE.

Availability

New capabilities are now available in the Proxmox Backup Server 2.2 release for all users. New users can download the ISO image, which can be easily installed on bare-metal, using the installation wizard. Proxmox Backup Server is free and open-source software, published under the GNU AGPL, v3 license.

For enterprise users, Proxmox Server Solutions GmbH offers a subscription-based support model, which provides access to the extensively tested Enterprise Repository, with regular updates via the web interface, as well as technical support on a subscription basis. Prices start at EUR 449 per server, including unlimited backup storage and unlimited backup-clients.

Proxmox Virtual Environment 7.2 available

2022-05-03T17:54:28+02:00

VIENNA, Austria – May 04, 2022 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") has today released Proxmox Virtual Environment 7.2. The new version of the server virtualization management platform is based on Debian 11.3 (Bullseye), but using a newer Linux kernel 5.15.30, and includes updates to the latest versions of leading open-source technologies for virtual environments, like QEMU 6.2.0, LXC 4.0.12, and ZFS 2.1.4. Proxmox VE supports Ceph Pacific 16.2.7, in addition to offering continued support for Ceph Octopus 15.2.16 (until mid 2022).

What’s new in Proxmox Virtual Environment 7.2

Backup/Restore:
- Notes templates: Meta-information can be added via a notes-template for backup jobs, to better distinguish and search for backups. This template is evaluated as soon as the job is executed, and added to any resulting backup. Notes templates can contain template variables like {{guestname}} or {{cluster}}.
- To benefit from the Rust code of Proxmox Backup Server, the Proxmox developers make use of perlmod, a Rust crate which allows exporting Rust modules as Perl packages. perlmod is used by Proxmox to transfer data between Rust and Perl, thus implementing parts of Proxmox VE and Proxmox Mail Gateway in Rust.
- The next-event scheduling code was updated via this Perl-to-Rust-binding (perlmod) and now uses the same code as Proxmox Backup Server. Users can not only specify the existing weekday, time, and time range, but now also a specific date and time (e.g., *-12-31 23:50; New Year's Eve, 10 minutes before midnight every year), date ranges (e.g., Sat *-1..7 15:00; first Saturday every month at 15:00), or repeating ranges (e.g., Sat *-1..7 */30; first Saturday every month, every half hour).
- Some basic restore settings, for example guest name or memory, can now be overwritten in the enhanced backup-restore dialog in the web interface.
- A new ‘job-init’ hook step was added to the backup process. Among other things, it can be used to prepare the backup storage, for example, by starting the storage server.
High Availability Manager:
- By improving the local resource manager (pve-ha-lrm) scheduler which launches workers, the amount of configurable services that can be handled per single node has increased. This helps in large deployments, as the services at the end of the queue are also checked to ensure that they are still in the target state.
- By introducing a skip-round command to the integrated HA simulator in Proxmox VE, it has become easier to test races in scheduling (on the different nodes).
Cluster: Regarding the creation of new VMs or containers, version 7.2 allows you to configure a desired range from which the new VMIDs are proposed via the web interface. The lower and upper boundaries can be set in the Datacenter -> Options panel. Setting lower equal to upper disables auto-suggestion completely, meaning the administrator has to manually enter an ID.
Ceph: Proxmox VE supports Ceph Pacific 16.2.7 and Ceph Octopus 15.2.16 (with continued support until mid 2022). This version now also supports creating and destroying erasure-coded pools, which can be added as Proxmox VE storage entries, and help to reduce the amount of disk space required. A new option in the GUI allows for passing the keyring secrets of external Ceph clusters when adding an RBD or CephFS storage to Proxmox VE.
Web interface: Further enhancements in the web interface allow for example for safe reassignment of a VM disk or CT volume to another guest on the same node; the reassigned disk/volume can be attached at a different bus/mountpoint on the destination guest. This can help in cases of upgrades, restructuring, or after disaster recovery.
Management: Many improvements in Proxmox VE 7.2 enable even more convenient management of the system. For example, a particular kernel version can be selected to boot persistently from a running system, through ‘proxmox-boot-tool kernel pin’. The selection can be used either indefinitely or just for the next boot. This eliminates the need to watch the boot process to select the desired kernel version in the bootloader screen.

Further enhancements and bug fixes

In the installation ISO, ZFS installs can be configured to use various compression algorithms (e.g., zstd, gzip, etc.).Additionally, the memtest86+ package, a tool aimed at memory failure detection, has been updated to the completely rewritten 6.0b.
Further improvements have been added to virtual machines (KVM/QEMU); one to highlight is support for the accelerated virtio-gl (VirGL) display driver. For VirtIO and VirGL display types, SPICE is enabled by default. In modern Linux distributions, changing the graphics card to VirGL can significantly increase frames per second (FPS). For Proxmox containers (LXC), many templates have also been refreshed or newly added, such as the NixOS container template.
The Proxmox VE Android app now provides a simple dark theme and enables it if the system settings are configured to use dark designs. The mobile app also provides an inline console by relaying noVNC for VMs, and xterm.js for containers and the Proxmox VE node shell in the GUI.
To prevent a network outage during the transition from ifupdown to ifupdown2, the ifupdown package was modified to not stop networking upon its removal.

Availability

Distribution upgrades from older versions of Proxmox VE are possible with apt. It’s also possible to install Proxmox VE 7.2 on top of Debian.

Proxmox Mail Gateway 7.1 available with Multi-Factor Authentication via GUI

2021-11-26T14:47:18+01:00

VIENNA, Austria – November 30, 2021 – Enterprise software developer Proxmox Server Solutions GmbH ("Proxmox" or the "Company") has today released Proxmox Mail Gateway 7.1, the latest version of its open-source email security solution. The Mail Gateway is a complete operating system based on Debian Bullseye 11.1, but using a newer Linux kernel 5.13, and OpenZFS 2.1.

The anti-spam and anti-virus filtering solution, available since 2005, functions as a full-featured mail proxy, that is deployed between the firewall and the internal mail server. It protects organizations against threats, such as spam, viruses, Trojans, and phishing emails. As one of the few open-source enterprise email filtering solutions available, Proxmox Mail Gateway continually provides updates to current versions of its underlying Linux distribution, helping companies to stay safe and up-to-date in a security sensitive domain.

What’s new in Version 7.1

Proxmox ships the latest upstream release of Apache SpamAssassin 3.4.6 with an updated rule-set for its Mail Gateway. PostgreSQL 13.5 is also included.

This release brings enhancements to the API. Support for IP configuration via DHCP has been added. While email still needs working DNS records, users can now manage and configure the IP for Proxmox Mail Gateway in the DHCP configuration. When adding a new entry to a ‘Who’ object, a duplicate check is performed before saving. Proxmox Mail Gateway uses the first search domain from /etc/resolv.conf as domain name - Version 7.1 can now also handle entries in domain names that have a trailing dot. Finally, support for delivery status notifications (DSN, RFC 3461) has been made available in before-queue filtering mode and improved for after-queue filtering.
Improved web interface: The configuration of LDAP backends via GUI has been improved. Changes can now be applied without specifying a password. Furthermore, the APT repository configuration, which was restricted to 'root', is now visible and editable by all users with 'Administrator' privileges. Some translations have been updated including Arabic, Basque, Brazilian Portuguese, French, German, Simplified Chinese, Traditional Chinese, and Turkish.
Multi-Factor Authentication for the GUI: Multiple second factors can now be configured for a single account. Web Authentication (WebAuthn), the general standard for authentication, one-time recovery keys and Time-based OATH (TOTP) are all available as second factors.

Availability

Proxmox Mail Gateway is released under the GNU Affero GPL, v3. The downloadable ISO image can be installed on bare-metal or a VM. The ISO contains an installation wizard that automatically installs and configures all the necessary components on the host. This eliminates the need for manual configuration later. The ISO contains the complete feature-set and can be downloaded at https://www.proxmox.com/downloads

Proxmox Backup Server 2.1 released

2021-11-05T18:14:57+01:00

VIENNA, Austria – November 23, 2021 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") has today announced version 2.1 of its open-source server backup solution. Proxmox Backup Server is based on Debian 11.1 “Bullseye”, but using the newer Linux kernel 5.13, and including OpenZFS 2.1. The whole software stack is written in Rust – a modern, fast, and memory-efficient language. The enterprise backup solution, capable of backing up and restoring VMs, containers, and physical hosts, supports incremental, fully deduplicated backups, significantly reducing network load, required storage space and, as a result, total cost of infrastructure.

What's new in Proxmox Backup Server 2.1

Improvements in Backup Management:

This version includes support for setting flexible traffic-control bandwidth limits. It enables the limiting of incoming (for example, backup) and outgoing (for example, restore) traffic from a set of networks. Users can now configure traffic control rules and set the limits to only apply during specific time-frames.
Protected backups: Backups can now be marked as “protected”, which will prevent them from being pruned or manually removed, without first removing the protected flag.
‘group-filter’ for sync jobs and tape-backup jobs: For each backup job, multiple, cumulative filters can be applied: Users can specify if they want to process only a specific backup type (ct, vm, host), a specific group, or a regex that matches the group-ID for such a job.

Improved Round-Robin Database (RRD): The RRD system has been optimized. It allows for storing and displaying time-series data. A much higher resolution in the dashboard is now possible with the following intervals; per-day: 1 min / per-month: 30 min / per-year: 6h / per-decade: 1 week. In total, data can be retained for 10 years. The database uses a journal, in order to avoid data loss.

Improved Support for OpenID Connect (OIDC): This version brings improved support for the open protocol standard OpenID Connect, which provides Single Sign-On (SSO). The improved OIDC integration in Proxmox Backup Server supports configuring an arbitrary username claim. The requested scopes for user information requests can now also be set, however, the default settings remain the same (‘profile’ and ‘email’). The prompt behavior, which was previously hard-coded to ‘login’, is now unset and can be configured to the variants defined in the OIDC specification or an arbitrary extension.

Enhancements to the Web Interface:

A new traffic-control management panel is available in the GUI;
Load and usage graphs have much higher resolution;
For tape backup jobs, the next tape media label is now displayed;
Improved translations for Arabic, Basque, Brazilian Portuguese, French, German, Simplified Chinese, Traditional Chinese, Turkish.

Enhancements in the Backend: A new debugging tool, proxmox-backup-debug, has been added, which can be used to inspect Proxmox Backup datastore files, verify the integrity of chunks, and in some cases, recover data.

Availability

Proxmox Backup Server is free and open-source software, published under the GNU AGPL, v3. The downloadable ISO image can be installed on bare-metal. The centrally managed software stack can be quickly installed using the installation wizard. Proxmox Backup Server 2.1 is now available for download at https://www.proxmox.com/downloads

Distribution upgrades from older versions of Proxmox Backup Server are possible via APT. It is also possible to install Proxmox Backup Server on top of Debian.

Proxmox Virtual Environment 7.1 released

2021-11-05T18:11:07+01:00

VIENNA, Austria – November 17, 2021 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") has released version 7.1 of its server virtualization management platform, Proxmox Virtual Environment today. The new version is based on Debian Bullseye 11.1, but using a newer Linux kernel 5.13, and includes updates to the latest versions of leading open-source technologies for virtual environments, such as QEMU 6.1, LXC 4.0, Ceph Pacific 16.2.6, and ZFS 2.1.

Proxmox Virtual Environment 7.1 comes with several new features: support for Windows 11 including TPM, enhanced creation wizard for VM/container, ability to set backup retention policies per backup job in the GUI, a new scheduler daemon supporting more flexible schedules, many improvements for management tasks in the web interface, and notable bug fixes.

What’s new in Proxmox Virtual Environment 7.1

Set backup retention per backup job via GUI: This allows users to set up smart backup policies for each backup job not only from the API and CLI, but also from the web interface.
Advanced scheduling options for backup jobs: Backup jobs in Proxmox VE are now run by a new scheduler daemon, called pvescheduler, which supports more flexible schedule options. This is already known from the verify and garbage collection jobs in Proxmox Backup Server (which in turn are inspired by systemd-timers). Additionally, backups can be marked as protected, which will prevent them from being pruned or manually removed, without first removing the protected flag.
For virtual machines, this version includes support for adding the Trusted Platform Module (TPM) 2.0 to any VM. Among other things, this allows users to install and run Windows 11. A TPM can be added easily via a checkbox in the web interface. Additionally, the UEFI secure boot functionality is now built in and enabled in the underlying QEMU package; the updated installation wizard allows you to select TPM v2.0 and UEFI. Newly created VMs have support for secure boot verification, with an option to have Linux distribution and Microsoft keys pre-enrolled.
Containers in Proxmox VE 7.1 now support Fedora 35 and Ubuntu 21.10 as well as AlmaLinux and Rocky Linux distributions, including templates. Container templates can be compressed with the open-source, lossless compression algorithm Zstandard (Zstd). For new, unprivileged containers created via the web interface, the nesting feature is enabled by default. This ensures better interoperability with modern systemd versions used in newer templates.
Two-factor authentication (TFA) has been further improved. To improve access control, multiple 2nd factors can be configured for a single account. WebAuthn (superseding U2F) and one-time recovery keys have been added. This can all be configured from the web interface.

Other notable enhancements

Creating virtual guests with multiple disks has been simplified. Additional disks can now be added from the creation wizard, eliminating the need to add them after creating the VM or container.
SCSI and Virtio VM disks can be marked read-only.
Ceph: Multiple CephFS instances are supported in Proxmox VE 7.1. The configuration of external Ceph clusters via API is now fully supported.

Availability

Proxmox Virtual Environment is free and open-source software, published under the GNU Affero General Public License, v3. The downloadable ISO image can be installed on bare-metal. Proxmox VE 7.1 is available for download at https://www.proxmox.com/downloads

Distribution upgrades from older versions of Proxmox VE are possible via APT. It’s also possible to install Proxmox VE 7.1 on top of Debian Bullseye.

Proxmox Backup Server 2.0 available

2021-07-09T16:59:30+02:00

VIENNA, Austria – July 13, 2021 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") has today announced the next major version 2.0 of its new open-source server backup solution. This version is based on Debian 11 “Bullseye”, but using the newer Linux kernel 5.11, and including OpenZFS 2.0. The whole software stack is written in Rust – a modern, fast, and memory-efficient language.

Proxmox Backup Server is an enterprise backup solution, capable of backing up and restoring VMs, containers, and physical hosts. By supporting incremental, fully deduplicated backups, the open-source backup solution significantly reduces network load, required storage space and, as a result, total cost of infrastructure. With the integrated web interface, users can easily manage and monitor all backup tasks from a single pane of glass and quickly recover single files, archives, and entire VMs in case of a disaster.

What's new in Proxmox Backup Server 2.0

Proxmox Tape Backup: Proxmox tape backup, which was released as a technology preview in Proxmox Backup Server 1.1, is now stable, providing an easy way to copy datastore content to tapes. Digital magnetic tape makes sense in any effective enterprise backup plan, especially for archiving large amounts of data. Proxmox Backup Server supports Linear Tape-Open generation 5 (LTO-5) or later drives (with best-effort support for LTO-4), including support for hardware encryption. The user space tape driver and support for autoloaders (pmtx) are also written in Rust.
Support for the open protocol standard OpenID Connect, providing Single Sign-On (SSO). It is possible to integrate external authorization servers, either using existing public services or your own identity and access management solution, for example, Keycloak or LemonLDAP::NG.
HTTP Proxy: Support for setting a HTTP Proxy for package updates and subscription check requests has been added.
Full integration of Let's Encrypt/ACME in the back and front end, with stand-alone and DNS plugins available. This enables administrators to easily create and deploy valid and trusted certificates for their domains with the Let's Encrypt certificate authority.
Management of APT repositories via GUI: The new 'Repositories' panel shows an in-depth status report, as well as a list of all configured repositories. The new panel provides an overview of all package repository configurations, warns about potential misconfigurations, and allows users to enable and disable a repository.
Update of the ExtJS JavaScript framework to the latest GPL release 7.0.
Improved Proxmox Installer: The Proxmox installer now has improved ISO detection, and can automatically detect HiDPI screens and increase console font and GUI scaling accordingly.
Single file-restore support for VMs that use ZFS or LVM internally. The unified, single-file restore has been extended to support restoring files from LVM(-thin) volumes and ZFS zpools that are contained within a VM archive. This functionality is accessible from the Proxmox VE GUI.

Proxmox Virtual Environment 7.0 with Debian 11 "Bullseye" and Ceph Pacific 16.2 released

2021-06-17T15:17:22+02:00

VIENNA, Austria – July 6, 2021 – Enterprise software developer Proxmox Server Solutions GmbH (or "Proxmox") today announced the stable version 7.0 of its server virtualization management platform Proxmox Virtual Environment. This major release is based on Debian 11 “Bullseye” but using a Linux kernel 5.11, and includes QEMU 6.0, LXC 4.0, and OpenZFS 2.0.4.

“The release of Proxmox VE 7.0 this time comes ahead of the stable release of Debian Bullseye. Although almost all packages were ready, the Debian project team postponed the release originally planned for May, due to an unresolved issue in the Debian installer. Since we maintain our own Proxmox installer, and are not affected by this particular issue, we decided to release despite the delay of Debian. The core packages of Proxmox VE are either already subject to the very strict Debian freeze policy for essential packages (for example, libc or compiler) or are maintained by our Proxmox developers (for example, QEMU, Kernel, Ceph, LXC, Rust compiler).”
Thomas Lamprecht - Lead developer at Proxmox

What’s new in Proxmox Virtual Environment 7.0

This major release brings a large set of new enhancements:

Ceph Pacific 16.2: Proxmox Virtual Environment fully integrates Ceph, giving you the ability to run and manage Ceph storage directly from any of your cluster nodes. This enables users to setup and manage a hyper-converged infrastructure. Ceph Pacific 16.2 is now the default in Proxmox VE, while Ceph Octopus 15.2 remains available with continued support.
- Beginning with Ceph Pacific 16.2, the balancer-module is enabled by default for new clusters. This will lead to better distribution of placement groups among the OSDs, and help to balance the data more evenly across OSDs reducing the chances that a single OSD is disproportionately full, resulting in less available space than expected in the cluster.
- Ceph monitors with multiple public networks can be created using the CLI, should users have multiple configured links.
Btrfs Storage Technology: The copy-on-write (COW) file system, natively supported by the Linux kernel, implements features such as snapshots, built-in RAID, and self-healing via checksumming for data and metadata. It allows taking subvolume snapshots and supports offline storage migration while keeping snapshots. For users of enterprise storage systems, Btrfs provides file system integrity after unexpected power loss, helps prevent bitrot, and is designed for high-capacity and high-performance storage servers.
New Panel for easy management of APT repositories via GUI: The Proxmox developers have added a new 'Repositories' panel to the web interface which allows to inspect a node's configured APT repositories. The new panel provides a single place to see all package repository configuration, which usually is scattered across multiple files, and warns about potential misconfiguration. Users can enable and disable repositories as needed, and add the standard repositories provided by Proxmox. For instance, it’s possible to test a new Ceph release which is not yet available in the main repository. The Ceph test repository, provided by Proxmox can simply be enabled (or added), the new version tested, and then disabled again when it’s not longer needed.
Access Control: The new open protocol standard OpenID Connect provides Single Sign-On (SSO) resulting in a seamless user experience. Administrators can integrate an external authorization server, by either using existing public services or their own identity and access management solution. Also, a newly added permission ‘Pool.Audit’ allows users to see pools, but not to change them.
Enhancements to the web-based user interface (GUI):
- Markdown in "Notes" -The “Notes” panels for Guest and Node can now interpret Markdown and render it as HTML. This gives administrators a better visualization of their notes.
- Pruning on manually triggered backups: Users can prune the target storage with its backup-retention parameters when starting a manual backup.
- Support for security keys (like YubiKey) as SSH keys, when creating containers or preparing cloud-init images.
QEMU 6.0: The latest QEMU version with new functionalities is included in Proxmox VE 7. This includes support for the Linux IO interface ‘io_uring’. The asynchronous I/O engine for virtual drives will be applied to all newly launched or migrated guest systems by default. Also a clean-up option for unreferenced VM disks is available. Disks, which are not present in the configuration, don't get automatically destroyed anymore. It is now opt-in in the API and with CLI tools (in the GUI it is present since Proxmox VE 6.4). If this clean-up option is enabled, only storage with content-types of VM or CT disk images, or rootdir will be scanned for unused disk-volumes, helping to prevent accidental data loss.
Container: LXC 4.0 has full support for cgroups v2, a mechanism for hierarchical organization of processes and allocation of system resources. A pure cgroup v2 layout is the default for Promox VE 7.0.
Proxmox VE Installer: The installer environment has been reworked and now uses switch_root instead of chroot, when transitioning from initrd to the actual installer. This improves module and firmware loading, and slightly reduces memory usage during installation. The installer now automatically detects HiDPI screens, and increases the console font and GUI scaling accordingly. This improves the UX for workstations with Proxmox VE (for example, for pass-through). The ISO detection has been improved as well to work more reliably with slower storages. The new installer uses zstd compression for the initrd image and the squashfs images.

Other notable enhancements

Certificate management: The ACME standalone plugin now has improved support for dual-stacked (IPv4 and IPv6) environments and no longer relies on the configured addresses to determine its listening interface.
Network: The modern ifupdown2 is the default network management tool for new installations using the Proxmox VE official ISO. The legacy ifupdown is still supported in Proxmox VE 7.
Time Synchronization: New installations will install chrony as the default NTP daemon, because the design limitations of systemd-timesync make it problematic for server use. Users upgrading from a system using systemd-timesyncd, should manually install either chrony, ntp or openntpd.

Availability

Proxmox Virtual Environment is free and open-source software, published under the GNU Affero General Public License, v3. The downloadable ISO image for Proxmox VE version 7.0 can be installed on bare-metal and is available at https://www.proxmox.com/downloads

Checklist tool ‘pve6to7’: Users can check their installation before, during, and after the upgrade process with the checklist tool ‘pve6to7’. It is included in the latest Proxmox VE 6.4 packages and provides hints and warnings about potential issues to clear up before upgrading. See https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0

Distribution upgrades from older versions of Proxmox VE or from a beta version of Proxmox VE 7.0 are possible with apt. It is also possible to install Proxmox VE 7.0 on top of Debian 11 “Bullseye”.

Ceph cluster upgrade: Upgrading Proxmox VE from version 6.4 to 7.0 first is necessary. Afterwards upgrading Ceph from Octopus to Pacific. For the detailed upgrade guides please see https://pve.proxmox.com/wiki/Ceph_Octopus_to_Pacific

Proxmox Virtual Environment 6.4 with Single File Restore and Live Restore released

2021-03-22T19:06:32+01:00

VIENNA, Austria – April 28, 2021 – Enterprise software developer Proxmox Server Solutions GmbH (or "Proxmox") has today released version 6.4 of its server virtualization management platform Proxmox Virtual Environment. This latest version comes with important new features such as live-restore and single file restore, support for Ceph Octopus 15.2.11 and Ceph Nautilus 14.2.20, many enhancements to KVM/QEMU, and notable bug fixes. The usability of Proxmox VE has improved significantly with the addition of many features and management options to the web interface.

The new version is based on Debian Buster 10.9, but using a newer, long-term supported Linux kernel 5.4. Optionally, the 5.11 kernel can be installed, providing support for the latest hardware. The 5.4 kernel remains the default on Proxmox VE 6.x series. The latest versions of leading open-source technologies for virtualization like QEMU 5.2, LXC 4.0, and OpenZFS 2.0.4 have been included. The Proxmox maintainers support two versions of Ceph, the massively scalable, distributed storage system, in their virtualization platform. During the installation process, users can select their preferred version, either Ceph Octopus 15.2.11 or Ceph Nautilus 14.2.20.

Single-File Restore and Live Restore for KVM

Proxmox Virtual Environment 6.4 brings Live Restore and Single File Restore enabling users to simplify restore tasks and further improve recovery time objectives (RTO).

Single-File Restore: Quite often, users only need to recover a single file. This feature is now available for virtual machine and container backup archives stored on a Proxmox Backup Server, meaning an individual file or directory can be selected for restore, without having to download the entire archive. To restore a file via the Proxmox VE web interface, users can open a file browser directly via the 'File Restore' button. A 'Download' button then allows the user to download files and directories, the latter being compressed into a zip archive on the fly. In case users want to download a VM image, which might contain untrusted data, Proxmox VE starts a temporary VM to download the data from it. This avoids exposing the hypervisor system to danger.
Live Restore: The new live restore feature can be enabled via the GUI or through the command ‘qmrestore’. The restore of a selected VM starts immediately after activation. This feature currently works for all VMs saved on a Proxmox Backup Server storage. It is especially useful for large VMs, for example, a web server, where only a small amount of data is required for the initial operation. The VM becomes operational as soon as the operating system and all necessary services have been started, while – in the background – the lesser used data is continuously restored.

Support for Ceph Octopus 15.2.11 and Ceph Nautilus 14.2.20

Proxmox Virtual Environment supports two versions of the massively scalable, distributed storage system Ceph. Users can select their preferred Ceph version-- Ceph Octopus 15.2.11 or Ceph Nautilus 14.2.20--during the installation process. The integration of the placement group (PG) auto-scaler has improved in version 6.4. This allows administrators to configure Target Size or Target Ratio settings and see the optimal numbers of PGs in the GUI. For easier usage, the Ceph pool view has been optimized, making it possible to show the columns related to the auto-scaler, as well as to configure the major pool properties from the web interface.

Further enhancements

Proxmox VE API Proxy Daemon: pveproxy listens to both IPv4 and IPv6 addresses by default. The Listening IP addresses are configurable in /etc/default/pveproxy. This can help to limit the exposure to the outside, e.g., by only binding to an internal IP.
Container: Appliance templates or support for Alpine Linux 3.13, Devuan 3, Fedora 34, and Ubuntu 21.04. Improved handling of cgroup v2 (control group).
External metric server: In Proxmox VE, you can define external metric servers, providing you with various statistics about your hosts, virtual guests, and storages. The new version supports InfluxDB HTTPs API and instances of InfluxDB behind a reverse proxy.
Improved ISO installer: The boot setup for ZFS installations is now better equipped for legacy hardware. Installations on ZFS now install the boot-loader to all selected disks, instead of only to the first mirror vdev, improving the experience with hardware where the boot-device is not easily selectable. Before installation, an NTP synchronization is attempted.
Storage: Proxmox VE 6.4 now allows for adding backup notes on any CephFS, CIFS, or NFS storage. Users can also configure a namespace for accessing a Ceph pool.
VMs (KVM/QEMU):
- Support pinning a VM to a specific QEMU machine version.
- Automatically pin VMs with Windows as OS type to the current QEMU machine on VM creation. This improves stability and guarantees that the hardware layout stays the same, even with newer QEMU versions.
- cloud-init: re-add Stateless Address Autoconfiguration (SLAAC) option to IPv6 configuration.
Enhancements to the GUI
- Show current usage of host memory and CPU resources by each guest in the node search-view.
- Use binary (1 KiB equals 1024 B instead of 1 KB equals 1000 B) as base in the node and guest memory usage graphs, ensuring it is consistent with the current usage gauge.
- Firewall rules: Columns are more responsive and flexible by default.

Notable bugfixes

Container restores now default to the privilege setting from the backup archive.
ZFS: Checking if a pool is mounted (in addition to imported) and trying to mount it, improves robustness for ZFS on slower disks.
Address issues with hanging qmp commands, causing VMs to freeze

Proxmox Backup Server 1.1 available with Tape Backup

2021-03-22T19:08:00+01:00

VIENNA, Austria – April 15, 2021 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") has today announced the release of Proxmox Backup Server 1.1. The new version is based on Debian Buster 10.9, but using a newer, long-term supported Linux kernel (5.4.106), and including ZFS 2.0. The whole software stack is written in Rust–a modern, fast, and memory-efficient language.

Proxmox Backup Server is an enterprise backup solution to back up and restore virtual machines, containers, and physical hosts. The client-server software supports incremental, fully deduplicated backups, and significantly reduces network load, required storage space and, as a result, total infrastructure cost. It seamlessly integrates into the virtualization management platform Proxmox Virtual Environment (Proxmox VE), allowing users to simply add a server as a new storage target.

Proxmox Tape Backup System (Technology Preview)

The new Proxmox tape backup, available as a technology preview in Proxmox Backup Server 1.1, provides an easy way to copy datastore content to tapes. Despite its age, digital magnetic tape continues to provide an easy and economical way for large amounts of data to be archived. Be it for compliance reasons or peace of mind, tape backup makes sense in any effective enterprise backup plan. The existence of WORM (write once read many) tapes, the low cost per unit, and the fast sequential write speeds are all clear benefits of tape based storage.

Proxmox Backup Server supports all Linear Tape-Open generation drives (LTO-4 and later), thus, it includes hardware encryption. Further details of what the Proxmox tape backup system offers are:

Tape backup jobs, which back up datastores to a media pool. Multiple datastores can be backed up to the same media set. It is possible to choose between writing all snapshots of a datastore to the media set or only the latest snapshot per group.
Tape restore jobs restore the contents of a media set to one or more datastores. By doing so, it is possible to restore multiple datastores from a media set, even if the system does not have the free disk space required in a single datastore.
Flexible retention policies such as: always recycle tapes, never recycle tapes, recycle tapes after a particular calendar event, etc.
New user space tape driver; written in Rust.
Support for various tape autoloaders: The Proxmox developers have rewritten the mtx tool in Rust (now called pmtx), thus most autoloaders supported by other tape-backup solutions available on Linux will work with Proxmox Backup Server.
If a stand-alone tape drive without an attached changer is deployed, users are notified via e-mail about necessary operations such as load/unload.
Components, jobs, and schedules can be configured via the web-based user interface.
With the Proxmox LTO Barcode Label Generator, a small web-app, users can generate and print bar-code labels for their tapes, on standard, adhesive label sheets.

Two-factor authentication (TFA) for the GUI

With Proxmox Backup Server 1.1, users can now set up Two-Factor Authentication (TFA) which adds another layer of security to the authentication process, making it harder for cybercriminals to access the network and take over accounts. The following second factors are available:

Time-base One-Time Password (TOTP) for clients such as FreeOTP, Google Authenticator, etc.
Web Authentication (WebAuthn): This is implemented by various security devices, like hardware keys or trusted platform modules (TPM) of computers and mobile phones.
Recovery keys for single use.

The two-factor authentication can be activated or configured via the GUI, by the users themselves or by a system administrator. TFA is complemented by the existing, token-based authentication for granting access to Proxmox Backup Server resources, for example, when configuring a Proxmox Backup Server storage in a Proxmox VE set up.

HTTP compression via Content-Encoding

Responses from the API of Proxmox Backup Server can get quite large, but can generally be compressed well. By adding support for deflate Content-Encoding, bandwidth utilization, transfer speed, and response times have been improved, especially over bandwidth constricted links.

Compression of file-level ZIP archive downloads

Downloading a directory from a file-level backup will now produce a compressed ZIP archive, reducing bandwidth and local space required.

Notable enhancements and bug fixes

Following the massive increase in deployments after the first stable release (1.0), a couple of bugs were reported by the community, which have now been fixed:

Improved handling of POSIX ACL entries on files.
Improved hand-over to new process when upgrading the Proxmox Backup Server packages.
Use of the local file system to handle synchronization, in order to avoid issues with locking on remote file systems (CIFS/NFS).
Changed HTTP timeouts to work more robustly, even over high latency and low bandwidth links, which are not uncommon for a remote backup site.
Error handling during garbage-collection has been improved, to handle cases wherein there is no more free space on a datastore file system.
Improved user experience when using a GPG master key.

Availability

Proxmox Backup Server is free and open-source software, published under the GNU Affero General Public License, v3. The downloadable ISO image can be installed on bare-metal. For a production setup, dedicated hardware is recommended. Proxmox Backup Server 1.1 is now available for download at https://www.proxmox.com/downloads

The backup server from Proxmox comes stocked with all the essential management tools, as well as an easy-to-use, web-based user interface. This allows for simple, out-of-the-box management of the server, either through the command line or a standard web browser.

For enterprise users, Proxmox Server Solutions GmbH offers a subscription-based support model, which provides access to the extensively tested Enterprise Repository, with regular updates via the web interface, as well as technical support on a subscription basis. Prices start at EUR 449 per server, including unlimited backup storage and unlimited backup-clients.

Proxmox Mail Gateway 6.4 released

2021-03-22T19:04:45+01:00

VIENNA, Austria – March 30, 2021 – Enterprise software developer Proxmox Server Solutions GmbH ("Proxmox" or the "Company") has released Proxmox Mail Gateway 6.4, the latest version of its open-source email security solution. Proxmox Mail Gateway is a complete operating system based on Debian Buster 10.9, but using Linux kernel 5.4.106, which is under long term support (LTS) status. The anti-spam and anti-virus filtering solution from Proxmox functions as a full featured mail proxy, that is deployed between the firewall and the internal mail server. It protects organizations against threats, such as spam, viruses, Trojans, and phishing emails.

New Features in Proxmox Mail Gateway 6.4

General certificate management via the web interface: It is now possible to upload custom certificates from the web interface, or set up a cluster-wide ACME account to automatically get and renew certificates from an ACME provider. The certificate file handling is implemented in the Rust programming language.
Proxmox Mail Gateway now offers full integration of the ACME protocol via the GUI. This enables administrators to create valid and trusted certificates for their domains with the Let's Encrypt certificate authority. The process is easily configurable from the web interface and has full support for the http-01 and dns-01 challenges.
Support for external SpamAssassin update channels (regular, automated updates): Proxmox Mail Gateway will now fetch verified updates from external rule channels, along with the updates from the SpamAssassin website (updates.spamassassin.org). Providing the channel’s URL and GPG key in a config-file is all that’s necessary. The KAM ruleset channel is now available, and a suitable configuration file is shipped with proxmox-spamassassin.
• Improved Spam Quarantine management for administrators: The admin view of the Spam Quarantine can now display the quarantined emails of all users at once.
TLS-logging improvements: The Proxmox Message Tracking Center now shows when an outbound connection is established over TLS. The pmg-log-tracker, the binary at the core of the Proxmox Message Tracking Center has already proven to provide optimized performance and more stability, since it’s extension and re-implementation in Rust a year ago (with version 6.2 of Proxmox Mail Gateway).
Enhancements to the integration of Proxmox Backup Server: If administrators have configured a Proxmox Backup Server-Remote, they can now get notification emails informing them about the result of a scheduled backup. Inclusion of the statistics database is now configurable on a per Remote basis.

Proxmox VE 6.3 with Proxmox Backup Server Integration and Ceph Octopus released

2020-11-13T18:02:45+01:00

VIENNA, Austria – November 26, 2020 – Proxmox Server Solutions GmbH, developer of open-source enterprise software, has today released version 6.3 of its server virtualization management platform, Proxmox VE. The new version is based on Debian Buster 10.6, but uses the latest long-term support Linux kernel (5.4), and includes updates to the latest versions of leading open-source technologies for virtual environments like QEMU 5.1, LXC 4.0, Ceph 15.2, and ZFS 0.85.

Integration for Proxmox Backup Server

The most notable new feature is the integration of the stable version 1.0 of Proxmox Backup Server, the company’s new, open-source, enterprise backup solution, for backing up and restoring VMs, containers, and physical hosts. Proxmox Backup Server supports incremental, fully deduplicated backups and facilitates strong encryption. The virtualization platform Proxmox VE is fully supported, allowing users to easily backup virtual machines and containers – even between remote locations. For virtual machines, Proxmox VE uses QEMU dirty-bitmaps, meaning backups from the Proxmox VE client to the Proxmox Backup Server are very fast, as only the changed data is transmitted.

In Proxmox VE 6.3, users just need to add the Proxmox Backup Server datastore as a new storage target. All client-to-server traffic can be encrypted on the client-side, to safeguard data before backing up to Proxmox Backup Server. The backup client makes creating and managing encryption keys simple. The program offers multiple ways to store keys, so that they remain safe and can be quickly obtained when needed:: Users can save key files to a secure file server or USB drive, copy the key as text into a password manager, or print the key on paper and, for example, store it in a safe.

Support for Ceph Octopus and Ceph Nautilus

Proxmox VE 6.3 supports Ceph Octopus 15.2.6 and Ceph Nautilus 14.2.15. Users can select their preferred Ceph version during the installation process. Many new Ceph-specific management features have been added to the Proxmox VE dashboard during the Ceph Octopus development cycle, including the displaying of recovery progress in the Ceph status panel.

In the new version, it’s now possible to view and set the placement groups (PGs) auto-scaling mode for each Ceph pool in the storage cluster. This brings a lot of flexibility to the Ceph storage cluster and reduces the maintenance effort. Ceph has been integrated in Proxmox VE since 2014 with version 3.2, and thanks to the Proxmox VE user interface, installing and managing Ceph clusters is very easy. Ceph Octopus now adds significant multi-site replication capabilities, that are important for large-scale redundancy and disaster recovery.

Enhanced Web Interface

With the integrated, web-based user interface, Proxmox VE makes configuring, managing, and monitoring the virtualized datacenter very straightforward, and with version 6.3 even more functionality and usability enhancements have been added. This includes:

Editing external metric servers: Proxmox VE nodes can be easily connected to InfluxDB or Graphite via the GUI to facilitate monitoring.
Improved editor for VM boot order: It is now possible to select multiple devices per type (disk, network) for booting. The user experience has been improved with drag-and-drop functionality.
Optional TLS certificate verification for LDAP and AD authentication realms.
Backup/Restore: Users can get an overview of all guests, which aren’t included in any backup at any backup state. Also, a detailed view per backup job is available, showing all covered guests and the disks which are backed up.
Optional comments for all storage types can be displayed in the web interface. Additionally, the Proxmox Backup Server displays the verification state of all backed up snapshots.

Further enhancements

Storage:
- The new backup retention settings allow users to adapt and control retention periods based on their business needs. For each storage or backup job, users can implement enhanced retention policies, and decide on how many backups to keep per time frame.
- To monitor SSD wear leveling, querying has been improved.
Container: Proxmox VE 6.3 now supports systems up to 8192 cores and officially supports Kali Linux and Devuan distribution containers, as well as the latest versions of Ubuntu, Fedora and CentOS. In addition, features such as per-container timezone support and improved startup monitoring have been added.
Many improvements to user and permission management have been included, such as support for using client certificates/keys when connecting to AD/LDAP realms and support for optional case-insensitive logins with AD/LDAP realms.
General improvements for virtual guests include improved handling of replicated guests when migrating.
Firewall: Improved API and GUI for matching ICMP-types.
Installer: Reboot automatically upon successful installation.

Proxmox Mail Gateway 6.3 with Proxmox Backup Server integration

2020-11-13T18:02:45+01:00

VIENNA, Austria – November 19, 2020 – Enterprise software developer Proxmox Server Solutions GmbH has today released version 6.3 of its open-source email security solution, Proxmox Mail Gateway. Proxmox Mail Gateway is a complete operating system based on Debian Buster 10.6, but using Linux kernel 5.4, the latest long-term support version. The anti-spam and anti-virus filtering solution functions as a full featured mail proxy, that is deployed between the firewall and the internal mail server. It protects organizations against spam, viruses, Trojans, and phishing emails.

New Features in Proxmox Mail Gateway 6.3

Proxmox Backup Server Integration: Proxmox Mail Gateway is fully supported by Proxmox Backup Server 1.0, the new, open-source, enterprise backup solution released on November 11, 2020. In Proxmox Mail Gateway 6.3, users can define multiple remote instances of Proxmox Backup Server to store backups on. In case of a large-scale disaster, they can then be quickly restored. It is also possible to schedule regular backups via the web interface, removing the need for manual backup creation and individual, scripted solutions.
Quarantine Link via login-page: If enabled by the system administrator, users can request mails containing a link to their quarantineview. This allows users to edit their individual blocklists, even if there are no mails in their quarantine. Until now this was only possible for sites using LDAP.
Enhancements to the Proxmox Message Tracking Center: To further improve the usability of Proxmox Mail Gateway, the pmg-log-tracker has been refined:
- Case sensitivity has been removed from the search box.
- In case the pmg-smtp-filter fails to process emails due to misconfiguration, they are marked as rejected.

Notable bugfixes:

DKIM signing now uses the longest matching domain for the 'd=' tag.
Emails held in the Attachment Quarantine are assigned a new Message-ID - fixing interoperability with certain downstream servers (for example, MS Exchange), which silently discard messages with duplicate Message-IDs.

Proxmox Backup Server 1.0 available

2020-11-09T18:11:38+01:00

VIENNA, Austria – November 11, 2020 – Proxmox Server Solutions GmbH has announced today the first stable release of its new, open-source server backup solution. Proxmox Backup Server 1.0 is an enterprise backup software solution to back up and restore virtual machines, containers, and physical hosts. It supports incremental, fully deduplicated backups, compression and authenticated encryption. The whole software stack is written in Rust, a modern, fast, and memory-efficient language. Proxmox Backup Server is based on Debian Buster 10.6, but using the latest long-term support Linux kernel (5.4), and including ZFS 0.8.4.

Designed as a client-server system, Proxmox Backup Server allows for storing data on-premises and remotely. This separation allows multiple, unrelated hosts to use the backup server, and, while the server stores the backup data and provides an API to create and manage datastores, the client tool allows the user to create and manage backups from all the hosts.

Key Features

Incremental, Deduplicated Backups: Proxmox backups are sent incrementally from the client to the Proxmox Backup Server, where data is deduplicated. Typically, changes between periodic backups are low. Reading and sending only the changes reduces the storage space used and the network impact. While periodic backups usually produce large amounts of duplicate data, the deduplication layer in the Proxmox Backup solution reduces that amount, reducing the required space for data storage too.
Proxmox VE Integration: The virtualization platform Proxmox VE is fully supported allowing you can easily backup virtual machines (supporting QEMU dirty bitmaps) and containers – even between remote locations. In Proxmox VE, users just need to add the Proxmox Backup Server datastore as a new storage backup target.
Administration: Proxmox Backup Server comes stocked with an integrated, web-based user interface to manage all backup and restore tasks on the server. Administration tasks are carried out through a web browser. In the web interface, users can create and manage datastores, browse and restore backups, manage network configuration and interfaces, and get an overview of performance, backup tasks, and usage statistics.
Data Integrity: All client-to-server traffic in Proxmox Backup Server will be encrypted to safeguard data integrity and ensure that the data is not compromised. For high performance on modern hardware, the authenticated encryption is done on the client-side with AES-256 in Galois/Counter mode (GCM). By using a master key (RSA public/private key pair), an encrypted version of the encryption key can be stored alongside each backup and recovered later, should the original key be lost. Additionally, this master key can be printed on paper so that it's safe from any system disaster.
As data is encrypted before it reaches the server, it is useless to unauthorized users accessing the server. This is important in case you want to back up to targets which are not fully trusted, like for example, rented servers at a colocation facility.
Checksum Algorithm: To ensure the accuracy and consistency of the data, Proxmox Backup Server uses a built-in SHA-256 checksum algorithm. This algorithm is used in backup verification to detect bit rot and confirm backups are safe. It’s also employed to find common data between backups of different machines (for example, multiple VMs with identical operating systems) - and store the data efficiently, only once.
Quick Restore with Granular Recovery: The need to minimize downtime and to quickly recover from data loss or ransomware attacks is a central aspect of IT administration. Proxmox Backup Server provides fast and simple restore via the web interface. With granular recovery options and via an interactive recovery shell, you can have a VM, archive, or even single file back in seconds.
Remote Synchronization: For redundancy, Proxmox Backup Server enables you to pull or synchronize datastores from other locations. This is an efficient method to synchronize data to or from remote hosts. Only changes since the previous sync get transferred.
Compression: The ultra-fast Zstandard (ZSTD) compression is able to compress several gigabytes of data per second. ZSTD is characterized by high compression ratio and very fast compression speed.
E-mail Notification: for scheduled background tasks (verification, pruning, garbage collection, sync jobs).
Access Control: A range of access control options are available to ensure users are limited to the rules the administrator provides to them. With one realm for system users and another realm for permissions and data ownership, the admin can specify exactly what each user is allowed to do on the server.

Availability

Proxmox Backup Server 1.0 is available for download at https://www.proxmox.com/downloads. The downloadable ISO image can be installed on bare-metal. For a production setup, dedicated hardware is recommended.

The backup server comes stocked with all the essential management tools, as well as an easy-to-use, web-based interface. This allows for simple, out-of-the-box management of the server, either through the command line or a standard web browser.

Proxmox Backup Server is free and open-source software, published under the GNU Affero General Public License, v3. Enterprise support is available from the Proxmox team on an subscription-based model. A subscription provides access to the stable enterprise repository package and to several technical support levels, starting at EUR 449.

Proxmox Mail Gateway 6.2 released

2020-04-21T12:17:11+02:00

VIENNA, Austria – April 28, 2020 – Proxmox Server Solutions GmbH has released Proxmox Mail Gateway 6.2, the latest version of its open-source email security solution. The Proxmox Mail Gateway, which also celebrates its 15th anniversary this April, is a complete operating system based on the latest stable release of Debian 10.3 (Buster) with a 5.4 Linux kernel. The Proxmox anti-spam and anti-virus filtering solution is a full featured mail proxy deployed between the firewall and the internal mail server. It protects organizations against spam, viruses, Trojans, and phishing emails. Proxmox ships the latest upstream release of Apache SpamAssassin 3.4.4 with an updated and enhanced ruleset (KAM rules added).

Main new features of Proxmox Mail Gateway 6.2

Rust for the Proxmox Message Tracking Center: The pmg-log-tracker, the binary at the core of the Proxmox Message Tracking Center, has been extended and re-implemented in the Rust programming language. pmg-log-tracker is responsible for providing the live searchable and grouped logs displayed in the web-based user interface, where the administrator can overview and control the mail flow from a single screen. The new pmg-log-tracker has support for parsing and grouping logs in before-queue filtering mode. Additionally, the new Rust code base provides optimized performance and more stability.

Before-Queue filtering mode via the GUI: With Proxmox Mail Gateway 6.2 the before-queue filtering can now be comfortably enabled with a simple click in the web interface and the logs can be displayed. Instead of accepting and silently discarding unwanted email, the Mail Gateway can optionally reject an email during the SMTP dialogue. By answering with a permanent failure code (554) there is no need to generate a non-delivery report, as this could cause the system to get blacklisted, due to Backscatter.

Customizable netmask length for greylist matching: As some cloud-providers send out one email from different IP addresses within a large network this can lead to a rather long delay and sometimes even to a legitimate email being rejected, when greylisting is enabled. With Proxmox Mail Gateway 6.2, the administrator can configure which hosts are considered to be belonging to the same network by setting a larger (or smaller) suffix instead of using “/24”.

Handling of changes to overridden templates with ucf: All service configuration templates, copied and modified in /etc/pmg/templates, get registered with ucf. Should an overridden template change with a new package version the administrator is asked and can accept or reject the changes. All users who have their templates in /etc/pmg/templates will be asked about the current changes for the initial registration.

Further enhancements

Better usability for the user Spam Quarantine interface: The ‘From’ header and the ‘Subject’ are now displayed on top of the mail body.
DKIM signing: The DKIM module can handle multiple selectors. With version 6.2 users can comfortably switch between the active selector in the GUI.
New What object: 'Match Archive Filename'
Support for downstream LMTP servers.

Availability

Proxmox Mail Gateway is released under the GNU AGPLv3. It is available as a bare-metal ISO install with an installation wizard that automatically installs and configures all necessary components on the host eliminating manual installation configuration. The ISO install contains the full feature-set and can be downloaded at https://www.proxmox.com/downloads

SPICE improvements: For a seamless remote access to virtual machines, a couple of SPICE enhancements are now available in the GUI. With Proxmox VE version 6.1 audio devices can be added without the need to edit the configuration file. Also video streaming can be enabled, and sharing folders between the SPICE client and a VM is possible (although still experimental). The SPICE USB device now supports USB3 (if using Qemu 4.1 or greater).
Backup/Restore: VMs with IOThreads enabled can be backed up with Proxmox VE 6.1. Additionally, administrators can run scheduled backup jobs manually from the Datacenter in the GUI.
Improvements to the HA stack:
- New 'migrate' shutdown policy: If the new migrate option is enabled, running services are migrated to another node on shutdown. As soon as the node comes back and the services were not manually moved to another node in the meantime, the services will move back.
- New 'crm-command stop': Shuts down a VM/container with the specified timeout and performs a hard stop if the timeout is 0. A VM or container stop command will be redirected to this new crm-command.

Other Notable Changes in Proxmox VE 6.1

For QEMU, the new 'reboot' API call enables to apply pending changes without having to wait for the guest to shutdown before starting it again. In Proxmox VE 6.1, PCI(e) passthrough now supports up to 16 PCI(e) devices.
Virtual guests can enable 'tags' in the guest configuration. This meta-information is very useful for configuration management with Ansible, Puppet, SaltStack, etc..
Software-defined Storage: In the Proxmox storage backend, all features offered by newer kernels with Ceph and KRBD are supported with version 6.1. For storing raw disk images, the .img file format is additionally allowed as an alternative to ISO images (.iso). The configuration of non-default 'mountpoint' properties for ZFS are allowed.
Improved certificate handling including compatibility for latest browsers. The lifetime of newly generated certificates has been reduced from ten to two years.
Firewall: Added support for 'raw' tables and use them to allow users to enable and configure Synflood-Attack protections.

Notable Bugfixes

The QEMU monitor timeout issue, which prevented successful backups in certain configurations, has been fixed. A number of bugs have been identified and fixed upstream in cooperation with corosync and kronosnet.

Proxmox Mail Gateway 6.1 released

2019-11-19T18:28:28+01:00

VIENNA, Austria – November 27, 2019 – Proxmox Server Solutions GmbH has released version 6.1 of its open-source email security solution Proxmox Mail Gateway. The anti-spam and anti-virus filtering solution is a complete operating system based on the latest Debian 10.2 (Buster) with a 5.3 kernel and uses the Postfix MTA, ClamAV and SpamAssassin. Deployed between the firewall and the internal mail server the Proxmox Mail Gateway works as a full-featured mail proxy and protects organizations against spam, viruses, trojans, and phishing emails.

Proxmox Mail Gateway 6.1 comes with updated SpamAssassin rules easily adjustable in the web-based user interface, added DKIM signature support for email authentication, and a new attachment quarantine. The high availability cluster usability brings improved handling of the Configuration and Rule changes.

Main new features of Proxmox Mail Gateway include:

DomainKeys Identified Mail (DKIM) signatures: Proxmox Mail Gateway 6.1 enables DKIM signatures for outbound emails improving email authentication. DKIM signing can be comfortably done in the web interface and it helps reduce phishing and spam and improves the sender’s email deliverability. With DKIM a domain name can be associated with an email message, thus verifying its authenticity. Signing in Proxmox Mail Gateway happens after processing the email with the internal Rule System, thus ensuring that it leaves the gateway with a valid signature. Inside a cluster, the use of one common SpamAssassin selector minimizes the overhead for adding the required DNS entries.

Attachment Quarantine: Administrators can now handle quarantined attachments in the GUI. The action Remove Attachments delivers the complete email to the attachment quarantine. The administrator can inspect the quarantined attachments safely in the GUI panel and choose weather to download only selected parts of the email for further analysis or to deliver or delete the email. For safety reasons, access is restricted to administrators only.

Adjustable SpamAssassin Rule Scores via GUI: The default scoring of the SpamAssassin rule-set can be adjusted in the web interface. This allows to adapt the scoring to a specific environment, thus achieving better ham/spam detection rates. The scoring adds weight to the rules and rules, causing false positives, can be selectively disabled.

Improved handling of Configuration and Rule changes in a cluster: The filtering engine gets notified about a range of configuration changes which require a reload. The notification is propagated during the cluster sync thus reducing situations where you had to manually restart “pmg-smtp-filter”.

Experimental: Support for Before Queue filtering: Proxmox Mail Gateway 6.1 can optionally reject an email during the SMTP dialogue, instead of accepting it and silently discarding unwanted email. By answering with a permanent failure code (554), there is no need to generate a non-delivery report, as this could cause the system to get blacklisted, due to Backscatter. This is an experimental feature because it needs to be explicitly enabled in /etc/pmg/pmg.conf and is currently not compatible with the tracking center.

Further enhancements include:

Ambiguously used terms in the GUI and the documentation have been clarified.
Improved documentation of the Service Configuration Templates, see https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#_service_configuration_templates and https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#_custom_spamassassin_configuration
Emails larger than 2 MB can now be downloaded as eml from the Spam Quarantine.

Proxmox VE 6.0 with Ceph Nautilus and Corosync 3

2019-07-16T10:25:33+02:00

VIENNA, Austria – July 16, 2019 – Proxmox Server Solutions GmbH, developer of the open-source virtualization management platform Proxmox VE, today released its major version Proxmox VE 6.0. The comprehensive solution, designed to deploy an open-source software-defined data center (SDDC), is based on Debian 10.0 Buster. It includes updates to the latest versions of the leading open-source technologies for virtual environments like a 5.0 Linux kernel (based on Ubuntu 19.04 "Disco Dingo"), QEMU 4.0.0, LXC 3.1.0, Ceph 14.2 (Nautilus), ZFS 0.8.1, and Corosync 3.0.2. Proxmox VE 6.0 delivers several new major features, enhancements, and bug fixes.

What’s new in Proxmox VE 6

Ceph Nautilus (14.2) and improved Ceph dashboard management: Proxmox VE allows to setup and manage a hyperconverged infrastructure with a Proxmox VE/Ceph-cluster. Version 6 integrates the features of the latest Ceph 14.2 release, and also brings many new management functionality to the web-based user interface. This includes: a cluster-wide overview for Ceph being displayed in the ‘Datacenter View’; a new donut chart visualizing the activity and state of the placement groups (PGs); the version of all Ceph services is displayed, making detection of outdated services easier; the configuration settings from config file and databases can be displayed; users can select the public and cluster networks in the web interface with a new network selector; encryption for OSDs can be activated easily during creation with a checkbox.
Cluster communication stack with Corosync 3 using Kronosnet: with Proxmox VE 6.0 the cluster communication stack has been updated to Corosync 3 by which the on-the-wire format has changed. Corosync now uses unicast as default transport method. This provides a better control of failovers as different networks can now be prioritized. A new selection widget for the network is available in the user interface helping to choose the correct link address and preventing users from making typos.
ZFS 0.8.1 with native encryption and SSD TRIM support: the new features for ZFS include enhanced security and data protection thanks to the added support for native encryption with comfortable key-handling by integrating the encryption directly into the `zfs` utilities. Encryption is as flexible as volume creation. TRIM support is included. The subcommand `zpool trim` notifies devices about unused sectors, thus TRIM can improve the usage of the resources and contribute to longer SSD life. Also checkpoints on pool level are available.
Support for ZFS on UEFI and on NVMe devices in the ISO installer: the installer now supports ZFS root via UEFI, for example you can boot a ZFS mirror on NVMe SSDs. By using `systemd-boot` as bootloader instead of grub all pool-level features can be enabled on the root pool.
QEMU 4.0.0: new QEMU functionalities are included in Promxox VE 6.0. Users can now use the web interface to live migrate guests with disks backed by local storage, and to set more VM CPU-flags. Support for more Hyper-V enlightenment has been added thus improving Windows performance in a virtual machine under QEMU/KVM.
Custom Cloudinit configurations: Proxmox VE 6 brings support for custom Cloudinit configurations and lets users store it as Snippet. The command `qm cloudinit dump` can be used to get the current Cloudinit configuration as a starting point for extensions.

Other Notable Changes in Proxmox VE 6.0

Automatic clean-up of old kernel images: the old kernel images are no longer marked as ‘NeverAutoRemove’ which helps to prevent problems when /boot is mounted on a small partition.
Guest status display in the tree view: Additional states for guests (migration, backup, snapshot, locked) are shown directly in the tree overview.
Improved ISO detection in the installer: the way how the installer detects the ISO has been reworked to include more devices, alleviating problems of detection on certain hardware.
Pool level backup: it’s now possible to create a backup task for a whole pool. By selecting a pool as backup target instead of an explicit list of guests, new members of the pool are automatically included and removed guests automatically excluded from the backup task.
Automatic rotation of the authentication key every 24h: by limiting the key lifetime to 24h the impact of key leakage or a malicious administrator are reduced.
The Node view in the user interface provides a faster syslog view.

By using Proxmox VE 6 as an open-source alternative to proprietary virtualization management solutions, enterprises are able to centralize and modernize their IT infrastructure and turn it into a cost-effective and flexible software-defined data center.

Proxmox VE 5.4 introduces new Ceph Installation Wizard

2019-03-29T10:59:40+01:00

VIENNA, Austria – April 11, 2019 – Proxmox Server Solutions GmbH today announced the availability of Proxmox VE 5.4, the newest release of its open-source platform for enterprise virtualization. Built on Debian 9.8 (“Stretch”) and a specially modified Linux Kernel 4.15, the Proxmox VE 5.4 introduces a new wizard for installing Ceph storage via the user interface, and brings enhanced flexibility with HA clustering, hibernation support for virtual machines, and support for Universal Second Factor (U2F) authentication.

The new features of Proxmox VE 5.4 focus on usability and simple management of the software-defined infrastructure as well as on security management:

Installing Ceph via user interface with the new wizard – Integrated into the Proxmox VE software stack since 2014 the distributed storage technology Ceph comes with own packages and support from the Proxmox team. The configuration of a Ceph cluster has already been available via the web interface, now with Proxmox VE 5.4 the developers have brought the installation of Ceph from the command line to the user interface making it extremely fast and easy to setup and configure a hyper-converged Proxmox VE/Ceph cluster. Additionally, enterprise on a budget can use commodity off-the-shelf hardware allowing them to cut costs for their growing data storage demands.
Greater Flexibility with High Availability improvements – Proxmox VE 5.4 provides new options to set the HA policy data center-wide, changing the way how guests are treated upon a node shutdown or reboot. This brings greater flexibility and choice to the user. The policy choices are:
- Freeze: always freeze services—independently of the shutdown type (reboot, poweroff).
- Fail-over: never freeze services—this means a service will get recovered to another node if possible and if the current node doesn’t come back up in the grace period of one minute.
- Default: this is the current behavior—freeze on reboot but do not freeze on poweroff.
Suspend to disk/hibernation support for Qemu/KVM guests – With Proxmox VE 5.4 users can hibernate Qemu guests independent of the guest OS and have them resumed properly on the next restart. Hibernation saves the RAM contents and the internal state to permanent storage. This allows users to preserve the running state of their qemu-guests across most upgrades to and reboots of the PVE-node. Additionally it can speed up the startup of guests running complex workloads, and also workloads which need lots of resources at initial setup, but free them later on.
Security: Support for U2F Authentication – Proxmox VE 5.4 supports the U2F (Universal 2nd Factor) protocol which can be used in the web-based user interface as an additional method of two-step verification for users. The U2F is an open authentication standard and simplifies the two-factor authentication. Since it is required in certain domains and environments this is an important improvement to security practices. The new U2F authentication and the TOTP second factor authentication can be configured by each user by themselves without needing a ‘User.Modify’- permission.
Improved ISO installation wizard – The Proxmox VE ISO installation wizard has been optimized offering the ability to go back to a previous screen during the installation. Users can adapt their choices made, without the need to restart the complete installation process. Before the actual installation, a summary page will be displayed containing all relevant information.
Improved Qemu Guest creation wizard - As often requested by the Proxmox community some options like for example Machine-type (q35, pc-i440fx), Firmware (Seabios, UEFI), or SCSI controller can now be selected directly in the VM creation wizard, and dependent options get set to sensible values directly.

By using Proxmox VE 5.4 as an open-source alternative to proprietary virtualization management solutions, enterprises are able to centralize and modernize their infrastructure and turn it into a future-proof software-defined data center.

Availability

Proxmox VE 5.4 is now available for download at https://www.proxmox.com/downloads. Proxmox VE comes with the free software license GNU AGPL, v3. Enterprise support is available from Proxmox Server Solutions on a subscription basis starting at EUR 79,90 per year and CPU.

Proxmox Mail Gateway 5.2

2019-03-18T14:55:02+01:00

VIENNA, Austria – March 26, 2019 – Enterprise software developer Proxmox Server Solutions GmbH has released Proxmox Mail Gateway 5.2, the latest version of its open-source email security solution. The Mail Gateway is a complete operating system based on Debian Stretch 9.8 with a 4.15 kernel. The anti-spam and anti-virus filtering solution, available for over 14 years, functions like a full featured mail proxy deployed between the firewall and the internal mail server and protects organizations against spam, viruses, trojans, and phishing emails.

Proxmox Mail Gateway 5.2 introduces a new mobile interface for the quarantine, making it very handy to check Delivery/Whitelist/Blacklist/Delete emails in the quarantine from any mobile device. The mobile interface is based on Framework7, a full featured open-source HTML framework for building Android and iOS apps.

The Proxmox Mail Gateway 5.2 release also introduces improvements in the LDAP integration, now allowing the use of Fully-Qualified Domain Names (FQDN) instead of IPs in the web user interface. Support for certificate verification (can be enabled for new deployments), and for LDAP+starttls has been added.

A new appliance template enables users to install the Proxmox Mail Gateway 5.2 as a privileged or unprivileged Linux Container. A new 'proxmox-mailgateway-container' Metapackage makes the installation of the template smaller and faster. As it does not depend on a kernel, it results in a reduced size and fewer updates.

The logging has been improved. The pmg-smtp-filter now logs each SpamAssassin rule’s score in addition to the rule names, therefore simplifying the analysis of the spam filter's performance without the need to access the email's source.

With improvements made to the TLS configuration of the web-based user interface, the pmgproxy can be configured via '/etc/default/pmgproxy' to disable or enable certain ciphers, compression, or cipher selection preferences.

Further improvements in Proxmox Mail Gateway 5.2

The new command `pmg-system-report` provides an overview of the key characteristics of the setup and performance in Proxmox Mail Gateway, and improves the initial diagnosis for the Enterprise support.
With the .eml download from the quarantine interface (non-mobile) users can download the complete source of a quarantined message in .eml format for further analysis.
Improved handling of Blacklist/Whitelist in the Quarantine interface: a ‘multiselect’ option for removing multiple entries at once has been added.
Added support for custom checks: This functionality enables users to integrate their own custom check logic by providing a defined interface which can be enabled optionally, and runs a custom check before the email gets handed to the virus scanner and the rule system.
Proxmox Mail Gateway cluster now works with IPv6.
proxmox-spamassassin: Update the shipped rule sets.

Availability

Proxmox Mail Gateway is released under the GNU Affero GPL, v3 and is available as a bare-metal ISO install with an installation wizard that automatically installs and configures all necessary components on the host eliminating manual installation configuration. The ISO install contains the full feature-set and can be downloaded at https://www.proxmox.com/en/downloads.

Enterprise support is available from Proxmox. Subscription prices start at EUR 99 per host and year for unlimited users and provides access to the extensively tested enterprise package repository with regular updates via the web interface. It is recommended for production use.

Proxmox VE 5.3 with CephFS released

2018-11-16T11:18:31+01:00

VIENNA, Austria – December 04, 2018 – Proxmox Server Solutions GmbH today unveiled Proxmox VE 5.3, its latest open-source server virtualization management platform. Proxmox VE is based on Debian Stretch 9.6 with a modified Linux Kernel 4.15. Ceph Storage has been updated to version 12.2.8 (Luminous LTS, stable), and is packaged by Proxmox.

Proxmox VE and CephFS

Proxmox VE 5.3 now includes CephFS in its web-based management interface thus expanding its comprehensive list of already supported file and block storage types. CephFS is a distributed, POSIX-compliant file system and builds on the Ceph cluster. Like Ceph RBD (Rados Block Device), which is already integrated into Proxmox VE, CephFS now serves as an alternative interface to the Ceph storage. For CephFS Proxmox allows storing VZDump backup files, ISO images, and container templates. The distributed file system CephFS eliminates the need for external file storage such as NFS or Samba and thus helps reducing hardware cost and simplifies management.

The CephFS file system can be created and configured with just a few clicks in the Proxmox VE management interface. To deploy CephFS users need a working Ceph storage cluster and a Ceph Metadata Server (MDS) node, which can also be created in the Proxmox VE interface. The MDS daemon separates metadata and data from each other and stores them in the Ceph file system. At least one MDS is needed, but its recommended to deploy multiple MDS nodes to improve high availability and avoid SPOF. If several MDS nodes are created only one will be marked as ‘active’ while the others stay ‘passive’ until they are needed in case of failure of the active one.

Further improvements in Proxmox VE 5.3

Proxmox VE 5.3 brings many improvements in storage management. Via the Disk management it is possible to easily add ZFS raid volumes, LVM, and LVMthin pools as well as additional simple disks with a traditional file system. The existing ZFS over iSCSI storage plug-in can now access LIO target in the Linux kernel. Nesting is enabled for LXC containers making it possible to use LXC or LXD inside a container. Also, access to NFS or CIFS/Samba server can be configured inside containers. For the keen and adventurous user, Proxmox VE brings a simplified configuration of PCI passthrough and virtual GPUs (vGPUs such as Intel KVMGT)–now even possible via the web GUI.

Countless bugfixes and smaller improvements are listed in the release notes and can be found in detail in the Proxmox bugtracker or in the Git repository.

Availability

Proxmox VE 5.3 is now available for download at https://www.proxmox.com/downloads. Proxmox VE comes with the free software license GNU AGPL, v3. Enterprise support is available from Proxmox Server Solutions on a subscription basis starting at EUR 74,90 per year and CPU.

Proxmox VE 5.2 with Cloud-Init and Let's Encrypt released

2018-05-11T14:28:55+02:00

VIENNA, Austria – May 16, 2018 – Proxmox Server Solutions GmbH, developer of the open-source virtualization platform Proxmox VE, today announced the general availability of version 5.2. Proxmox VE 5.2 comes with new features like the Cloud-init package for automation of VM provisioning, a CIFS/SMB storage plug-in, and the Let’s Encrypt certificate management via the graphical user interface. The Proxmox development team further expands the cluster functionality making the creation and configuration of Proxmox VE clusters possible via the web interface. The open-source virtualization management platform Proxmox VE 5.2 is based on Debian 9.4, and an updated and modified Linux Kernel 4.15.

Cloud-Init support for automating VM provisioning

Proxmox VE 5.2 now supports Cloud-Init, a multi-distribution package that handles initial setup of a virtual machine as it boots for the first time, and allows provisioning of VMs that have been deployed based on a template. With the Cloud-Init package Proxmox users can easily configure host names, add SSH keys, set up mount points or run post-install scripts via the graphical user interface. It also enables for example automation tools like Ansible, Puppet, Chef, Salt, and others to access pre-installed disk images and copy a new server from that.

SMB/CIFS Storage Plug-in

The flexible Proxmox VE storage model now integrates a SMB/CIFS storage plug-in manageable via the web interface. CIFS, as well as NFS, are the primary file systems used in network attached storage (NAS). CIFS is the "Common Internet File System" used by Windows operating systems for file sharing and it allows to connect to Windows file servers or other SMB-compatible servers with the SMB/CIFS backend.

Let’s Encrypt Certificate Management via GUI

With the new version 5.2 Proxmox users can now manage their Let’s Encrypt certificates via the Proxmox interface, easing the work of administrators significantly. Let’s Encrypt is an automated and open certificate authority (CA) providing free, digital certificates needed to enable secure HTTPS (SSL/TLS) for websites. Proxmox users already have been able to create Let’s Encrypt certificates since version 4.2, now they can issue and renew the certificates with two simple clicks via the web interface.

Proxmox VE 5.2 delivers numerous additive features for improved usability, scalability, and security including:

Creation of clusters via the graphical user interface. This feature makes creating and joining nodes to a Proxmox cluster extremely simple and intuitive even for novice users.
Expanded functionality of LXC: Creating templates or moving disks from one storage to another now also work for LXC. The move-disk function can be used for stopped/paused containers and instead of backup/restore.
If the QEMU guest agent is installed, the IP address of a virtual machine is displayed on the GUI
Administrators can now easily create and edit new roles via the GUI.
Setting I/O limits for restore operations is possible (globally or more fine-grained per storage) to avoid I/O load getting too high while restoring a backup.
Configuration of ebtables in the Proxmox VE Firewall.

Availability

Proxmox VE 5.2 is now available for download at https://www.proxmox.com/downloads. Proxmox VE is licensed under the free software license GNU Affero GPL, v3. Enterprise support is available from Proxmox Server Solutions on a subscription basis starting at EUR 74.90 per year and CPU.

Proxmox VE celebrates its 10-year anniversary

2018-04-13T11:44:36+02:00

VIENNA, Austria – April 16, 2018 – This week marks the tenth anniversary of the open-source project Proxmox Virtual Environment (VE), developed and maintained by Austrian-based Proxmox Server Solutions GmbH. The complete open-source platform for enterprise virtualization was announced in a first public version 0.9 exactly ten years ago on April 15, 2008 and the software allowed to manage KVM and OpenVZ on a single management interface. Since then, five major and numerous minor versions of Proxmox VE have been produced.

Today, the current version Proxmox VE 5.1 allows system administrators to control their entire virtualized IT environment with a single management tool. The comprehensive Proxmox VE feature-set supports two virtualization technologies (KVM and LXC – since version 4.0), includes flexible networking, a RESTful API, a high availability cluster stack, software-defined storage, backup/restore functionality, a firewall, and many more out-of-the-box tools and seamlessly integrated open-source technologies. Since version 5.1 Proxmox VE also integrates Ceph storage 12.2.x Luminous LTS, for building hyper-converged infrastructures.

Two virtualization technologies on a single platform

Ten years ago the Proxmox developers were to be the first to tie together the two virtualization technologies KVM and containers (initially OpenVZ) on a single platform and made them easily manageable via a web-based interface. When starting development of Proxmox VE in 2007, the two Proxmox founders, Dietmar Maurer (CTO) and Martin Maurer (CEO), designed it as a bare-metal install CD containing a highly-tweaked version of Debian GNU/Linux optimized for use as a virtualization server. They used a modified Linux kernel which included all the support needed for KVM and OpenVZ. Shortly after the first public release, the first stable version of Proxmox VE 1.0 was available in 2008 containing new features that enabled users to virtualize demanding Linux and Windows applications workloads, apply live migration, and backup their data with vzdump backups on the GUI.

“It's hard to believe that Proxmox VE is ten years old today, and great to see how popular it has become,” says Martin Maurer, co-founder and CEO at Proxmox. “When we started Proxmox VE there was no management interface on the market for managing KVM or OpenVZ easily. We were, as far as I know, one of the first projects to mash-up support for virtual machines and containers on a central GUI. Proxmox VE was designed to meet that need, and over the years it has added so many more features and scaled to meet the demands of enterprises and users alike who want an open-source platform to easily manage compute, network, and storage.”

Open-source platform to easily manage compute, network, and storage

Today, Proxmox VE is translated into 19 languages and has about 200,000 installed hosts in over 142 countries. The company Proxmox Server Solutions offers subscription-based access to technical customer support and stable repository packages. More than 11,000 customers ranging from mid-market to large enterprises, non-profits, and home users have an active subscription. Plans are ranging between 75 and 800 Euros per CPU and year, and provide access to technical support and the stable enterprise-repository that delivers heavily tested and validated packages.
The ten-year-old open-source project Proxmox VE, licensed under the free/open-source license GNU Affero GPL, v3, offers regular releases and continuing development, and has become the open-source alternative to proprietary solutions for data center virtualization or for complex cloud management solutions.

“Proxmox VE has grown into a powerful enterprise virtualization management platform that allows our users to easily manage their whole virtualized infrastructure,” says Martin Maurer. “We look back on the past ten years of Proxmox VE and we are grateful to everyone who made the project a success: our users, customers, and partners that are constantly supporting and pushing us with feedback and new feature requests. Most importantly, we are thankful for our fantastic team and all of their hard work and their input. The architectural design of our platform and the open-source development model allows us to constantly adapt to newest technologies and adjust Proxmox VE to the growing IT demands of our community. For our next version, Proxmox VE 5.2 we have for example Cloudinit on the roadmap which we hope will make a lot of our users happy.”

Dashboards and statistics provide a quick overview for the IT staff easing their control tasks. If desired advanced tasks can be executed on the command line too.

Integrated Reference Documentation

Proxmox Mail Gateway brings a new documentation framework integrated into the GUI which provides a global help function. Users can access and download the technical documentation via the central help-button (available in various formats like html, pdf and epub). A main asset of the new documentation is that it’s always version specific to the current user’s software version. The new reference documentation is created from man pages which are auto-generated based on the code. The help content itself is written by the developers via comments in the code and is generated using asciiDoc. To participate in the documentation project users can send a patch to the project and propose new content.

We are extremely excited that we could update the framework of our Proxmox Mail Gateway to a 100 % open-source solution. The licensing change to a free software license allowed us to apply the same framework and ecosystem like we already use for our open-source virtualization platform Proxmox VE. Proxmox Mail Gateway has been successfully on the market since twelve years, and our constantly growing customer number always liked the comprehensive yet easy-to-use platform. With the new version 5.0 we think that we will positively increase our customer’s user experience and provide them an efficient tool to easily protect their infrastructure from malicious email attacks.

Proxmox VE 5.1 with production-ready Ceph Lumious

2017-10-19T11:29:46+02:00

VIENNA, Austria – October 24, 2017 – Proxmox Server Solutions GmbH, developer of the open-source virtualization platform Proxmox Virtual Environment (VE), today announced the release of its version 5.1. Most important enhancement is the software-defined storage solution Ceph v12.2 Luminous which is now stable for production and included in the enterprise support agreement. Proxmox VE 5.1 is based on Debian 9.2 and comes with a 4.13 Linux kernel.

Proxmox VE 5.1 with production-ready CEPH Luminous

Proxmox VE 5.1 comes with production-ready Ceph cluster packages. The virtualization platform integrates Ceph v12.2 Luminous, the long term stable release of the software-defined storage solution. Users can now implement Ceph clusters as distributed storage solution in production. Help and support is provided by the Proxmox team via the Proxmox VE subscription service. Ceph is a distributed object store and file system designed to provide excellent performance, reliability and scalability. The Ceph OSD storage backend Bluestore FS is the new default in Proxmox VE. Bluestore delivers more performance (up to 200 percent in certain use cases), full data check-summing, and it has built-in compression.

With Proxmox VE 5.1 the Proxmox VE Ceph cluster packages are now prepared by the Proxmox developers. This means that bugfixes can be packaged and used faster with Proxmox VE. The new packaging procedure allows users to access the newest Ceph features with Proxmox VE immediately, and they don’t have to wait for the packaging done by Ceph which sometimes took weeks.

ZFS 0.7.2 Storage

After updating the integrated ZFS 0.7.2 in Proxmox VE 5.1 statistics are now optimized, and analyzing storage usage is even better now. The resumable “zfs send/receive” allows an interrupted ZFS receive to be resumed if the stream was prematurely terminated due to remote system or network failure. Also the new release brings reduced CPU usage and improved performance through hardware accelerated check summing.

Many other notable changes in Proxmox VE 5.1 can be seen on the web-based management interface. The dialog for “Create VM” has been improved and contents are merged together for easier selection. On the high availability management dialog VMs can now be selected via a drop-down menu instead of entering the identifier of a VM manually. The system management level has seen optimizations with shutdown (services optimized, bug fixes). The packaging format Open Virtualization Format (OVF) can now be imported directly via command line. SLES container (instead of openSUSE) are supported in Proxmox VE 5.1.

Availability

Proxmox VE 5.1 is available for download now at https://www.proxmox.com/downloads
The Proxmox VE solution is licensed under the free software license GNU Affero GPL, v3. Enterprise support is available from the company Proxmox Server Solutions GmbH on a subscription basis starting at EUR 69,90 per year and CPU.

Proxmox VE 5.0 with new open-source storage replication stack

2017-07-03T20:30:22+02:00

VIENNA, Austria – July 4, 2017 – Proxmox Server Solutions GmbH, developer of the open-source platform for enterprise virtualization Proxmox VE, today announced the general availability of its major release Proxmox VE 5.0. New main features are the open-source storage replication stack for asynchronous replication, and updates to the fully integrated distributed storage Ceph RBD, now packaged by the Proxmox team. With Proxmox VE 5.0 the import of disk images from other hypervisors such as VMware or Hyper-V to Proxmox VE has become far easier. The new version 5.0 is based on Debian 9 codename “Stretch” and a specially modified Linux Kernel 4.10.

New Proxmox VE storage replication stack

Proxmox VE 5.0 introduces a new open-source storage replication stack for enterprise virtualization workloads, fully integrated into the easy-to-manage web management interface. Replicas provide asynchronous data replication between two or multiple nodes in a cluster, thus minimizing data loss in case of failure. The storage replication feature is especially designed to help smaller organizations to improve reliability, fault-tolerance, and accessibility of their data. For all organizations using local storage the Proxmox replication feature is a great option to increase data redundancy for high I/Os avoiding the need of complex shared or distributed storage configurations.

Proxmox users can now easily create, modify and remove replication jobs on the web GUI. The flexible Proxmox replication scheduler is based on the systemd time calendar event format allowing to configure scheduling, frequency and times. The minimum replication time can be even set to one minute. Replication also speeds up migration of data between nodes. This new tightly integrated Proxmox VE storage replication technology sets the base for many new features in future Proxmox VE releases.

Ceph – massively scalable, software-defined storage

With Proxmox VE version 5.0 Ceph Rados Block Device (RBD) becomes the de-facto standard for distributed storage in Proxmox VE. Ceph is a highly scalable software-defined storage solution integrated with VMs and containers into Proxmox VE since 2013. It enables organizations to deploy and manage compute (VMs and containers) and storage centrally from Proxmox VE web interface removing the need for additional costly storage infrastructure and leveraging hyper-converged infrastructures.
The new version Proxmox VE 5.0 now integrates the Ceph packages directly into the Proxmox VE repository. Packaging is done by the Proxmox developers instead of getting the deb packages from ceph.com. This will allow Proxmox to roll-out future bug-fixes as soon as they are available to its users.

Supporting Quotes: Martin Maurer, founder and CEO, Proxmox:
“Our users love the Ceph integration shipped with Proxmox VE. Since we first implemented the powerful distributed storage in 2013 with Proxmox VE 2.3, we see numerous community members running Ceph implementations in production, also with blazing fast NVMe SSDs. Thanks to their input we could extremely improve the integration over the last four years, and the result is now a perfectly integrated Ceph storage support into the Proxmox storage stack enabling enterprises to manage their Ceph storage directly from the Proxmox VE interface. For the future, we are extremely excited about what’s coming next from the great Ceph community, just thinking about CephFS. We have already tested the new ‘bluestore’-format in the Ceph Luminous 12 release candidate and we have seen speed increase by up to 50% in some of our setups! We plan to provide the new ‘bluestore’-OSD format as default in Proxmox VE as soon as Ceph Luminous is production ready, later this summer.”

Other notable changes in Proxmox VE 5.0

Another new feature in Proxmox VE 5.0 is the simplified import procedure for disk images from different hypervisors. Users can easily import disks from VMware, Hyper-V, or other hypervisors via a new command line tool called ‘qm importdisk’.
Other important improvement is the new live migration with local storage via QEMU. Also, the GUI team has made many updates to the web interface such as added USB und Host PCI address visibility, and bulk actions now visible in the GUI. The screen size of the console has been adjusted, and filtering options have been integrated to the GUI.

Availability

Proxmox VE 5.0 is available now and ready for download at https://www.proxmox.com/downloads. Distribution upgrades from Proxmox VE 4.4 or 5.0 beta versions are possible with apt. The Proxmox VE solution is licensed under the free software license GNU Affero GPL, v3. Enterprise support is available from Proxmox Server Solutions on a subscription basis starting at EUR 69,90 per year and CPU.

Proxmox VE 4.3 released

2016-09-23T17:00:46+02:00

VIENNA, Austria – September 27, 2016 – Proxmox Server Solutions GmbH today announced the general availability of Proxmox Virtual Environment 4.3. The hyper-converged open source server virtualization solution enables users to create and manage LXC containers and KVM virtual machines on the same host, and makes it easy to set up highly available clusters as well as to manage network and storage via an integrated web-based management interface.

The new version of Proxmox VE 4.3 comes with a completely new comprehensive reference documentation. The new docu framework allows a global as well as contextual help function. Proxmox users can access and download the technical documentation via the central help-button (available in various formats like html, pdf and epub). A main asset of the new documentation is that it is always version specific to the current user’s software version. Opposed to the global help, the contextual help-button shows the user the documentation part he currently needs.

The new reference documentation is created like the former Proxmox technical documentaion: manpages are autogenerated based on the code, help content itself is written by the developers via comments in the code. Then for generating the docu the Proxmox VE project uses asciiDoc. To participate in the documentation project users can send a patch to the open source projet for proposing new content. The former documentation, the Proxmox VE wiki, stays public, links to the reference documentation, and hosts all the howtos, use cases, etc.

The updated vertical GUI structure is one of the main advancements made to the GUI of Proxmox VE 4.3. Proxmox developers re-arranged some of the horizontal menus in the GUI framework Sencha ext JS 6 introduced with Proxmox version 4.2 and they are now vertical. This structure alsoallowed the Proxmox developers to build groups, add icons, and optimize the logical navigation structure. The flat design of the sencha theme made this step essential as menus weren’t very well recognizable. The vertical structure now shows every menu in a single line.

In the newly added groups content is unfolded and displayed by default. The same menus as in the old structure are shown. Users can choose to fold or unfold groups. For minimal supported displays the new vertical structure now provides more space in total.

More new features in the GUI:

New status overview for host, VM, container and storage.
Signal colors have been added and show for example when capacity of a CPU is used.
Diskmanagment: new disk overview, including S.M.A.R.T., and wearout for enterprise SSDs. Diskmanagement is new to the GUI; it used to be only accesible via Ceph and command line.
Defaults for VM creation: The wizard “Create VM” now proposes optimal settings dependent to the selected Linux-based operating system. For example, the default for Linux is “virtio scsi disk”.
Open console with double-click on VM or container (allow popups first)
Search function in the GUI (“ctrl-shift-f”)
“Task log”-window remembers its window size

Proxmox VE is a bare-metal ISO installer, based on latest Debian Jessie 8.6 combined with a long term Linux 4.4 kernel, based on Ubuntu 16.04 LTS (Xenial Xerus) with LXC 2.0. Proxmox VE 4.3 has also seen many bug fixes and optimizations, for example with snapshots and rollback and LVM thin.

Proxmox VE 4.2 Released

2016-04-20T11:03:11+02:00

VIENNA, Austria – April 27, 2016 – Proxmox Server Solutions GmbH, the company developing the server virtualization platform Proxmox Virtual Environment (VE), today announced the general availability of version 4.2. The open source virtualization platform Proxmox VE is a hyper-converged solution enabling users to create and manage LXC containers and KVM virtual machines on the same host, and makes it easy to set up highly available clusters, as well as to manage network and storage via an integrated web-based management interface.

The new Sencha Ext JS 6 framework brings a modern 'flat design' look and feel to the Proxmox VE GUI with a reworked icon set providing consistency and an optimal user experience. In the 'Summary View' data information is now visualized in graphs which gives the user an overview of all his performance data. Browser variations are handled automatically so that the charts always display correctly. The graphs provide enhanced interactive features such as click zoom. With the new Ext JS framework more settings moved from the command line to the GUI such as LXC mount point options or syslog date filtering. Translations for French, German, Italian, and Norwegian were updated within the new GUI, which is translated into 19 languages in total.

New LVM-thin and ZFS improvements help increase storage utilization
Proxmox VE is a bare-metal ISO installer, based on latest Debian Jessie 8.4 combined with a long term Linux 4.4 kernel, based on Ubuntu 16.04 LTS (Xenial Xerus). With Proxmox VE 4.2 logical volumes can now be thin provisioned and therefore the Proxmox bare-metal ISO installer offers LVM-thin or ZFS with just one click. A storage administrator can dedicate more capacity to virtual machines than they have and create logical volumes that are larger than the available extents. This ability offers great flexibility and can be expanded dynamically when needed and can help avoiding the need to purchase additional storage because of unused, over-allocated storage.

Another new feature is that ZFS storage can now be selected during the installation process. If the admin chooses ZFS, the ZFS-Plugin will be automatically configured out-of-the-box and the user does not have to re-configure it later.

New SSL certificates with “Let's Encrypt”
Proxmox VE 4.2 now works with the free web server certificates from “Let’s Encrypt”. “Let’s Encrypt” is a free, automated, and open certificate authority providing free SSL certificates with short expiry and automated renewal. This significantly simplifies the process of getting and maintaining a certificate for secure websites with simple commands. The objective of “Let’s Encrypt” and the ACME protocol is to make it possible to set up an HTTPS server and have it automatically obtain a browser-trusted certificate, without any human intervention. This is accomplished by running a certificate management agent on the web server.

Proxmox VE 4.2 is available now and ready for download at http://www.proxmox.com/downloads Proxmox VE is licensed under the free software license GNU Affero GPL, v3. For companies, Proxmox Server Solutions GmbH offers commercial support subscriptions starting at EUR 64,90 per year and CPU.

Proxmox VE 4.0 with Linux Containers (LXC) and new HA Manager Released

2015-09-25T17:38:04+02:00

VIENNA, Austria – October 6, 2015 – Proxmox Server Solutions GmbH today released version 4.0 of its Proxmox Virtual Environment (VE). The open-source server virtualization solution enables users to create and manage containers and KVM virtual machines on the same host as well as to set up highly available clusters via an integrated web-based interface.

The new version is based on Debian Jessie 8.2.0 with an upgrade on kernel 4.2, QEMU 2.4 and the latest Ceph Server packages (0.94.x – hammer release). Most significant changes include the new Proxmox VE HA Manager with integrated HA Simulator, and the move to container-based virtualization with Linux Containers (LXC) replacing the former OpenVZ. Other new capabilities introduced in Proxmox VE 4.0 include an embedded NoVNC console, DRBD9 (as technology preview), and complete IPv6 support on all levels from virtual machines, to containers, and hosts.

Highly available Clusters with Proxmox VE HA Manager

The new resource manager for multi-node high availability clusters is the Proxmox VE HA Manager. It monitors all virtual machines and containers on the whole cluster and gets automatically into action if one of them fails. The HA Manager works out of the box, and with watchdog-based fencing simplify deployments dramatically. The whole HA settings can now be configured via the integrated web GUI. The Proxmox VE HA Manager, developed by the Proxmox team, replaces the former RGManager.

Proxmox VE now makes high availability accessible to the masses by allowing system administrators to configure complex HA cluster settings intuitively via the web GUI. By integrating software watchdog, external fencing devices become dispensable in basic configurations.

Proxmox HA Simulator

Proxmox VE 4.0 also comes with a new Proxmox HA Simulator allowing users to learn and test the proper usage of the Proxmox VE HA solution prior to going into production. The simulator can be installed on any node and simulates a cluster with three nodes and six virtual machines. Users can start it right after installation and test the HA fail-over and behavior for different scenarios like for example complete loss of one node or loss of the network.

Linux Containers (LXC)

The new version 4.0 of the Proxmox Virtual Environment supports now Linux containers (LXC) replacing OpenVZ as the container solution. LXC works with all modern and latest Linux kernels and is fully integrated into the Proxmox VE frameworks, especially into the storage model. Proxmox VE 4.0 is the first version to allow using LXC on almost all storage plug-ins such as Ceph, ZFS, NFS, DRBD9 or local storage. LXC provides a lightweight OS containerization, tools for container management and a wide choice of container OS templates. Users can manage containers easily via the web interface but also on the command line with PCT, a tool to manage Linux Containers (LXC) on Proxmox VE. A five-step migration path to migrate from existing OpenVZ containers to LXC is already available in the wiki of the Proxmox VE project.

All new TurnKey GNU/Linux V14 Appliances will arrive soon as LXC templates (still under development).

Proxmox VE 4.0 is now generally available for download at
http://www.proxmox.com/downloads

The Proxmox VE 3.x family will be maintained in the future, approximately until the end of Debian Wheezy security updates (expected end in April 2016).

Supporting Quotes:

The move from OpenVZ to LXC allowed us to finally update to the latest and greatest kernel improving even more the security, scalability and robustness of the whole Proxmox VE platform. We are also really excited that with the new Proxmox HA manager our users can now setup and deploy highly available clusters easily and simply configure them in the GUI.
Martin Maurer - CEO of Proxmox Server Solutions GmbH.

Proxmox Celebrates 10-Year Anniversary

2015-02-18T20:16:32+01:00

From a self-funded open-source startup to a worldwide tech business

Vienna (Austria) – April 29, 2015 – Proxmox Server Solutions GmbH today is celebrating its 10th birthday.

Proxmox VE 3.4 released with ZFS filesystem, ZFS storage plugin, hotplug

2015-02-18T20:16:32+01:00

Vienna (Austria) – February 19, 2015 – Proxmox Server Solutions GmbH today released version 3.4 of its open source server virtualization management platform Proxmox Virtual Environment (VE). Highlights are the integrated ZFS file system, a ZFS storage plug-in, hotplug and NUMA support (non-uniform memory access), all based on latest Debian Wheezy 7.8. The Proxmox developers considered many user feature requests and added many GUI improvements like start/stop all VMs, migrate all VMs or disconnect virtual network cards.

The integrated ZFS (OpenZFS) is an open source file system and logical volume manager in one, allowing huge storage capacities. Starting with the new ISO installer for Proxmox VE 3.4, users can now select their preferred root file system during installation (ext3, ext4 or ZFS). All ZFS raid levels can be selected, including raid-0, 1, or 10 as well as all raidz levels (z-1, z-2, z3). ZFS on Proxmox VE can be used either as a local directory, supporting all storage content types (instead of ext3 or ext4) or as zvol block-storage, currently supporting KVM images in raw format (with the new ZFS storage plugin).

Using ZFS allows advanced setups for local storage like live snapshots and rollbacks but also space and performance efficient linked templates and clones. The ZFS storage plugin in Proxmox VE 3.4 complements already existing storage plugins like Ceph or the ZFS for iSCSI, GlusterFS, NFS, iSCSI and others.

The new hot plugging feature for virtual machines allows installing or replacing virtual hard disks, network cards or USB devices while the server is running. If hot plug is not possible, the new “pending changes” (marked now in red) show that the changes need a power off to be applied - the admin always overviews the actual status of his changes.

“ZFS in Proxmox VE 3.4 is absolutely powerful,” says Martin Maurer, CEO of Proxmox Server Solutions. “Users can replace cost intense hardware raid cards by moderate CPU and memory load, and it’s combined with easy management.” Maurer summarizes “By using ZFS, our users can achieve maximum enterprise features with low budget hardware – but they should not forget to add a SSD for a fast cache (L2ARC and ZIL).“

Download
Proxmox VE 3.4 is released under the free open-source license GNU AGPL, v3 and is available as ISO-image for download at http://www.proxmox.com/downloads. For enterprise customers, Proxmox offers subscriptions starting at 59.90 euros per year and CPU socket.

Facts and Milestones
Proxmox VE is used by more than 67.000 hosts in over 140 countries. The active community counts almost 26.000 forum members. The GUI is translated in 19 languages including Farsi, Basque and the two official forms of Norwegian Bokmål and Nynorsk.

Proxmox VE 3.3 released with HTML5, Proxmox VE Firewall, Two-factor authentication, ...

2014-09-15T11:27:59+02:00

Vienna – September 15, 2014 – Proxmox Server Solutions GmbH, developer of the open source server virtualization solution Proxmox Virtual Environment (VE), today released version 3.3. The series of new features focus on security and include the Proxmox VE Firewall and two-factor authentication. A HTML5 console, the ZFS storage plugin and the Proxmox VE Mobile touch interface extend the range of use. Many package updates are included in the release.

Highlight of the new release is the Proxmox VE Firewall. It has a distributed nature and is designed to protect the whole IT infrastructure. Completely integrated into the web-GUI and the cluster stack, it allows the user to setup firewall rules for all hosts, the cluster, virtual machines and containers. To keep these tasks simple, the Proxmox VE Firewall comes with features like firewall macros, security groups, IP sets and aliases. While configuration is stored on the cluster file system layer, the iptables run on each cluster node providing full isolation between individual virtual machines. In contrast to a central firewall solution, the distributed nature of the Proxmox VE Firewall provides a higher bandwidth, and at the same time avoids bottlenecks.

The newly integrated two-factor authentication will add an extra layer of security to Proxmox VE. With version 3.3, login with a one-time password (OTP) can be enabled to the username/password interface login – this works for all authentication realms, including LDAP or Active Directory. The Proxmox developers offer two different methods: YubiKey from Yubico and Time Based One-Time Passwords (with OATH). These secure login processes shall help to prevent unauthorized persons or programs to access the virtualization servers.

The new HTML5 console (noVNC) is set as the default in Proxmox VE 3.3. It works on every platform (Windows/Linux/OSX), even on mobile devices and supersedes the installation of the Java plugin or SPICE viewer.

In addition to the full featured web interface, Proxmox VE Mobile is a touch interface designed specifically for the use on mobile devices (phones and tablets). It is just a HTML5 app built with Sencha Touch and it runs on any mobile with a modern browser. Proxmox VE Mobile includes a lot of key functionalities needed to manage virtualization on the go, including the HTML5 and the SPICE console. It is meant as an additional help for the admin, but not to replace the full admin interface. Proxmox VE Mobile also supports two-factor authentication like a YubiKey with NFC.

Availability of Proxmox VE 3.3:
Proxmox VE 3.3 is released under the AGPL, v3 and is available as ISO-image for download at http://www.proxmox.com/downloads For enterprise customers, Proxmox offers subscriptions starting at EUR 49.90 per year and CPU socket.

Facts and Milestones Proxmox VE

Proxmox VE 3.2 with SPICE, Ceph and Open vSwitch released

2014-03-10T15:00:56+01:00

Vienna - March 10, 2014 - Proxmox Server Solutions GmbH, developer of the open source server virtualization platform Proxmox Virtual Environment (VE), today released version 3.2. Big enhancements in this release are the SPICE multi-monitor remote viewer for virtual servers and containers (with spiceterm), the distributed Ceph storage system and Open vSwitch. Countless updates are added like qemu 1.7, improved live backup, support for VMware™ pvscsi and vmxnet3, a new ZFS storage plugin, latest NIC drivers and bug fixes.

Ceph Storage Server Integration
Proxmox VE 3.2 includes the ability to build the Ceph storage cluster directly on Proxmox VE hosts. Ceph is a massively scalable, open source distributed object store and file system that is very popular in many cloud computing deployments. Proxmox VE 3.2 supports Ceph's RADOS Block Device (Ceph RBD) to be used for VM disks. Ceph storage cluster can be administered via the Proxmox web GUI and configuration is stored in Proxmox' shared file system (pmxcfs) which is replicated throughout the cluster. Ceph is a redundant system and has no single point of failure, which makes it perfect for critical environments.

SPICE and spiceterm
Proxmox VE integrates the Simple Protocol for Independent Computing Environments (SPICE) since version 3.1 as technology preview. With the new version 3.2, the user can now choose between SPICE and VNC for accessing the virtual machine consoles. Plenty of improvements were made: By using spiceterm, a program developed by Proxmox, SPICE can be additionally used for accessing OpenVZ containers or the host shell. A spiceterm console can be resized and offers a fully functional keyboard including special characters like the pipe or @ symbol and function keys like control-c do work. On the client side, it is sufficient to install a SPICE remote viewer. Virt-viewer packages are available for Linux and Windows, and for Android there is compatible App named aSPICE.

Open vSwitch
Another enhancement of Proxmox VE in version 3.2 is the introduction of the network software switch Open vSwitch (OVS) on the host network level (a technology preview in 3.2). Open vSwitch is a multilayer virtual switch enabling massive network automation, while still supporting standard management interfaces and protocols as well as distribution across multiple physical servers. It consists of user space tools and kernel modules.

"We are totally excited with the new Proxmox VE 3.2 because it challenges the virtualization market with Ceph storage and SPICE," states Martin Maurer, CEO of Proxmox Server Solutions. "With the integrated Ceph RBD, Proxmox users get a highly available solution with no single points of failure and extreme scalability. This makes it ideal for applications which require high available flexible storage."

Availability of Proxmox VE 3.2
Proxmox VE 3.2 is released under the AGPL, v3 and is available as free ISO-image for download at http://www.proxmox.com/downloads
For enterprise customers, Proxmox offers subscriptions starting at EUR 49,90 per year and CPU socket.

Proxmox Virtual Environment 3.1 with SPICE, GlusterFS storage plugin and new Enteprise Repository

2013-06-03T17:55:13+02:00

New Version includes SPICE, GlusterFS storage plugin and a new enterprise repository

VIENNA - August 21, 2013 Proxmox Server Solutions GmbH, developer of the open source server virtualization management solution Proxmox Virtual Environment (Proxmox VE), today announced the release of version 3.1. This version comes with new features and services including two new package repositories, updates via GUI, SPICE, the new GlusterFS storage plugin, and a significant price drop on the community subscription service from monthly EUR 9,90 to EUR 4,16.

New Enterprise Repository
Proxmox Server Solutions, maintainer of the Proxmox VE repositories, introduces two new package repositories named "pve-enterprise" and "pve-no-subscription". Beginning with Proxmox VE 3.1, the default repository is the Proxmox VE Enterprise repository. It allows secure access to stable updates, security patches and bug-fixes and is available to subscription users only. Proxmox VE users who do not want to use the subscription service can access the packages via the "pve-no-subscription" repository. These packages are not heavily tested, therefore the No-subscription repository is not recommended for production servers.

Updates via GUI
The newly integrated update feature shows the administrator all available updates, security patches and bug-fixes via GUI and also via email notification. Refreshing the update list and upgrading the system can be done with just a few clicks. Changelogs are visible in the GUI. Upgrading via command line (CLI) is still possible.

SPICE (Simple Protocol for Independent Computing Environments)
Spice achieves a user experience similar to an interaction with a local machine, while trying to offload most of the intensive CPU and GPU tasks to the client. Spice is suitable for both LAN and WAN usage, without compromising on the user experience. Using Spice on Proxmox VE is easy and secure: It is integrated in the cluster environment, the user- and authentication system, and all traffic is fully encrypted. Proxmox VE 3.1 introduces Spice as a technology preview. The VNC console is still available and the default.

GlusterFS storage plugin
This new storage plugin supports the use of GlusterFS volumes. It uses a fuse mount point for volume management (create/delete/snapshot,rollback,...) but Qemu accesses the virtual disk images directly to get best performance.

Significant Price Drop for Community Subscription
With the new release Proxmox permanently drops the pricing for its Community subscription service from EUR 9,90 to now EUR 4,16 per month and CPU-socket. This signifies a 58 percent price drop. The entry-level subscription enables access to the new Enterprise repository and the stable software updates.

With the new subscription pricing and the stable Enterprise repository we improved our service for our enterprise users. The new service allows IT professionals and businesses to rely on a stable and secure virtualization solution to run on production servers. This allows them to benefit from open source software on the one hand and from stable update services and guaranteed support on the other hand.
Martin Maurer - CEO of Proxmox Server Solutions GmbH

Proxmox Virtual Environment Celebrates 5th Anniversary

2013-06-04T10:01:12+02:00

VIENNA - April 15, 2013 - Proxmox Virtual Environment, the open-source server vitualization platform, is celebrating its 5th anniversary today. When Vienna Proxmox Server Solutions launched the first version of Proxmox VE V0.9 on April 15, 2008, exactly five years ago, the software was the first open-source solution providing an integrated GUI for KVM and container-virtualization. With this approach IT administrators can manage their KVM and OpenVZ containers easily via a web-based interface. In the last five years Proxmox VE has become the mainstream open-source business alternative to commercial virtualization platforms like VMware vSphere, Microsoft Hyper-V, Oracle VM or Citrix XenServer.

According to Proxmox, today 40.000 hosts in more than 140 countries worldwide use Proxmox VE with a continued growth of its user base. The GUI is available in more than 16 languages and the support forum states over 20,000 members. Proxmox Server Solutions offers several levels of support subscription plans for business-use, ranging between 120 and 800 Euros per year.

"When we first released Proxmox VE in 2008, there was no open-source GUI solution for container-virtualization with OpenVZ suitable to our needs," explains Martin Maurer, CEO of Proxmox. "That's why we developed Proxmox VE. Most virtualization projects focused on XEN, but after we tested KVM, we realised that this technology was more suitable to our needs. Now, five years later, KVM is the best established hypervisor in almost all Linux distributions. Proxmox VE is still one of the easiest to use but also very flexible open-source virtualization products, combining KVM and containers on one platform."

The Proxmox VE project offers regular releases and continuing development and is backed by independent and profitable Proxmox Server Solutions GmbH, headquatered in Vienna.

KVM backup and restore
The key feature of Proxmox VE 2.3 is the new KVM backup and restore, replacing LVM snapshots. The benefit of KVM live backup is that it works for all storage types including VM images on NFS, iSCSI LUN, Ceph RBD or Sheepdog. The new backup format is optimized for storing VM backups fast and effective (sparse files, out of order data, minimized I/O).
The V2.3 also includes the latest QEMU/KVM version 1.4 with many improvements as well as GUI support for the storage of KVM VM disks on Ceph RADOS Block Device (RBD) storage system.

Dynamic Memory Management
Optimized and effective memory management is a key factor in virtualization environments. KSM and Auto-Ballooning enables sophisticated and economic configurations for physical RAM utilization. Memory ballooning (KVM only) allows you to have your guest dynamically change it’s memory usage by evicting unused memory during run time. It reduces the impact your guest can have on memory usage of your host by giving up unused memory back to the host.

„Proxmox Virtual Environment 2.3 is the open-source business alternative to VMware vSphere, Microsoft Hyper-V, Oracle VM or Citrix XenServer“, says Martin Maurer, CEO of Proxmox Server Solutions GmbH. In addition to regular product updates, a huge and active community (more than 20.000 community forum members) and a worldwide partner network Proxmox VE users can benefit from services like business support subscriptions and trainings.

Proxmox Training - Demand for KVM Virtualization Professionals on the Rise

2013-06-04T13:35:25+02:00

VIENNA, January 18th, 2013 - Proxmox Server Solutions GmbH, developer of the open-source virtualization platform Proxmox Virtual Environment (PVE), announced today the new training catalog for 2013. Starting in February, the Austrian-based company offers a new set of training courses for their virtualization product Proxmox VE. „Our training courses address system administrators who want to become a qualified virtualization professional or who are planning to move to our open-source virtualization platform“, says Martin Maurer, CEO of Proxmox Server Solutions GmbH.

Focus turns on employees with training in virtualization
As the global enterprise IT sector continues its shift toward virtualization, IT decision-makers have altered their hiring plans to focus more heavily on employees with training and experience in virtualization. “We have received numerous requests for Proxmox VE technical trainings from prospective students all over the world. To respond to this demand, we have opted for offering the courses” explains CEO Martin Maurer. „Users want to understand the concepts and philosophy behind Proxmox VE and they want to learn all about Kernel-based Virtual Machines (KVM) and container-virtualization with OpenVZ.“ Proxmox VE unifies these technologies in one single open-source platform.

Upward trend in server virtualization
The amount of companies looking to move to a virtualization solution will likely grow moving forward. Virtualization saves time and money, uses existing resources, reduces administration, and increases reliability. Well known products for virtualization are VMWare vSphere, Citrix Xen Server or Windows Hyper-V. However, more and more companies decide to move to a cheaper and more flexible open-source solution.

Open-source alternative in virtualization
One of these open-source alternatives is the virtualization platform Proxmox Virtual Environment at version 2.2. The software is based on a linux kernel and combines the two technologies Kernel-based Virtual Machine (KVM) and OpenVZ containers. This offers a wide range of application. Small and medium businesses as well as big companies, educational institutions or hosting providers use the software worldwide. Main features of Proxmox VE 2.2 are high availability cluster, live snapshots, simple configuration via web GUI, live migration and live backup. Proxmox Server Solutions GmbH also offers commercial support subscriptions for business use.
