We are excited to announce the first release of Proxmox Virtual Environment with official support for a second CPU architecture: 64-bit ARM (arm64/aarch64). Until now, Proxmox VE was available for x86-64 (amd64) only.

Proxmox VE 9.2 for arm64 shares the code base, package repositories, and release lifecycle with its x86-64 counterpart. It is built on Debian 13.5 "Trixie" with Linux kernel 7.0 as the stable default, and ships the same versions of our underlying key technologies, including QEMU 11.0, LXC 7.0, and ZFS 2.4. Configuration, tooling, and documentation are identical to x86-64, except for a small set of architecture-specific differences listed below.

Platform support

• Fully supported on the NVIDIA Grace Hopper and NVIDIA Vera platforms
• Best-effort support on other UEFI-based ARMv9-A or newer hardware (ARMv8-A generally works as well, likewise best-effort)
• The host must boot through UEFI and describe its hardware through ACPI
• Device-tree-only single-board computers, such as the Raspberry Pi, are not supported

Architecture-specific differences

• Virtual machines always boot through UEFI, provided by the ARM build of OVMF (AAVMF). SeaBIOS is not available on arm64.
• AMD SEV memory encryption and Intel GVT-g mediated vGPUs are x86-only.
• There is no operating-system-level CPU microcode package, unlike
  intel-microcode
  and
  amd64-microcode
  on x86.
• Guests only run on nodes matching their architecture, and live migration is only possible between nodes of the same architecture.

A special thank you goes to NVIDIA for their trust and their close collaboration on this port, which allowed us to develop, test, and harden Proxmox VE on arm64. It is already deployed in production on the supported platforms today. See more:
https://www.proxmox.com/en/about/co...ox-ve-for-nvidia-mission-control-ai-factories

We are working together with further enterprise server vendors on their ARM efforts and hope to expand the list of officially supported hardware platforms in the future.

FAQ

Q: Is Proxmox VE on arm64 a technology preview?
A: No. Proxmox VE on arm64 is fully supported on the platforms listed above, with the same release lifecycle and support windows as the x86-64 builds.

Q: Is there an enterprise repository, and is enterprise support available for arm64?
A: Yes. The pve-enterprise repository is available for arm64, and as on x86-64 we recommend it for production use. Hosts with an active subscription get enterprise support with the same service levels as on x86-64, through the usual customer portal.

Q: How do I get a subscription for an arm64 host?
A: Subscriptions for arm64 are separate from the x86-64 ones and are currently available on request. Please contact our sales team for a quote: [email protected]

Q: Will other Proxmox products become available for arm64?
A: We already have internal test builds for some of our products, for example Proxmox Backup Server, and are confident that we can bring them up to our release standards. Which products we prioritize depends on the requirements of our enterprise customers, so if this is relevant for you, please contact our business channels with details about your enterprise setup: [email protected]

Q: Which hardware is officially supported?
A: The NVIDIA Grace Hopper and NVIDIA Vera platforms. Other UEFI-based ARMv9-A or newer server hardware is supported on a best-effort basis; ARMv8-A hardware generally works too, also best-effort.

Q: Can I run Proxmox VE on a Raspberry Pi or a similar single-board computer?
A: No. An arm64 host must boot through UEFI and describe its hardware through ACPI. Device-tree-only boards and legacy boot are not supported.

Q: Can I mix x86-64 and arm64 nodes in one cluster?
A: This is not blocked technically, but mixed-architecture clusters are not officially supported. Note that guests only run on nodes of their own architecture, and live migration across architectures is not possible.

Q: Can I move an existing guest from an x86-64 node to an arm64 node?
A: The guest's data can be moved through offline migration, backup and restore, or shared storage, but the guest has to be reinstalled or reconfigured for the new architecture before it starts.

Q: Can I install Proxmox VE on top of Debian 13 "Trixie" for arm64?
A: Yes, the procedure is the same as on x86-64, see https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_13_Trixie

Q: Are the package versions the same as on x86-64?
A: Both architectures are built from the same sources and track the same versions. Individual packages can be released later on arm64, as we currently have fewer systems available for validating that architecture.

Q: Where can I get more information about feature updates?
A: Check the roadmap, forum, the mailing list, and/or subscribe to our newsletter.

Today we're introducing a dedicated repository for debug symbol packages, reachable at https://dbgsym.proxmox.com/.

Debug symbol packages (named -dbgsym) contain the detached debug information for their matching binary package. They are not needed for normal operation, but let tools such as gdb, systemd-coredump, or crash produce useful backtraces when analyzing a crash or hang.

Effective immediately, these packages are served from this separate repository instead of being mixed into the regular ones, for the Debian 12 (Bookworm) and Debian 13 (Trixie) based releases (and newer) of Proxmox VE, Proxmox Backup Server, Proxmox Mail Gateway and Proxmox Datacenter Manager.

To enable it, add the repository for your product. For example, for Proxmox VE on Trixie, create /etc/apt/sources.list.d/pve-dbgsym.sources:

Code

Types: deb
URIs: https://dbgsym.proxmox.com/debian/pve
Suites: trixie
Components: pve-dbgsym
Signed-By: /usr/share/keyrings/proxmox-archive-keyring.gpg

Adjust the product (pbs, pmg, pdm) and suite (bookworm) accordingly. Then install the -dbgsym package matching the binary you want to debug.

A few notes:

• If you previously installed debug packages from the standard repositories, add this repository to keep getting them.
• The debug symbol repository is publicly available for all of the above products; there is no test, no-subscription, or enterprise distinction. As debug symbols are inert, you can safely use them for production or test systems alike.
• Like our other repositories, the release files are signed with a GPG key stored on a Hardware Security Module (HSM), so package authenticity is verified independently of the transport.
• The archive resides on separate CDN nodes to reduce load on our main CDN pool, especially from mirrors not using an efficient, application-aware approach. We recommend using Proxmox Offline Mirror for APT repository mirroring.

Best regards,
Thomas

Our BIG thanks go out to all of our community members, dedicated testers, and developers whose ongoing support, bug reports, and code contributions made this release possible. We invite everyone to dive in, try out the new provisioning options and the cross-remote views, and share your experiences, questions, or ideas right here in this discussion thread!

FAQ

Q: How does this integrate into Proxmox Virtual Environment and Proxmox Backup Server?
A: You can add arbitrary Proxmox hosts or clusters as remotes. Proxmox Datacenter Manager will then monitor them and provide basic management using only the API.

Q: How many different Proxmox VE hosts and/or clusters can I manage with a single Datacenter Manager instance?
A: Due to the early stage of development, there are still some pain points, but we are confident that we will be able to handle large setups with a moderate amount of resources. We have run tests with over 5000 remotes and over 10000 virtual guests to confirm the performance expectations of our new UI framework. We are targeting similar numbers for the backend.

Q: What Proxmox VE and Proxmox Backup Server versions are supported?
A: The minimum required Proxmox VE version is 8.4 and the minimum required Proxmox Backup Server version is 3.4.
We will support all actively supported Proxmox project releases, but encourage frequent upgrades of both PDM and the PVE and PBS remotes to leverage all features.

Q: Can I upgrade a 1.0 installation to the stable 1.1 via apt?
A: Yes, upgrading from 1.0 is possible via apt and GUI. We recommend using the
pdm-enterprise repository
on upgrade for the most stable experience.

Q: Can I upgrade Proxmox Datacenter Manager Alpha to this 1.1 version?
A: Yes, please follow the upgrade instructions on
https://pve.proxmox.com/wiki/Proxmox_Datacenter_Manager_Upgrade_from_Alpha_to_1

Q: How are the bearer tokens for the automated installation workflow managed?
A: Bearer tokens are scoped per installation and can be reviewed and revoked at any time from the Proxmox Datacenter Manager UI. See the documentation for details on the recommended lifecycle.

Q: Can I install Proxmox Datacenter Manager alongside Proxmox VE or Proxmox Backup Server?
A: Yes, but installing alongside other Proxmox projects is not the recommended setup (expert use only).

Q: What environment does Proxmox Datacenter Manager support?
A: Proxmox Datacenter Manager will work everywhere where a standard x86-64/AMD64 Debian system is supported.

Q: Are there any recommended system requirements for the Proxmox Datacenter Manager?
A: Yes, see
https://pdm.proxmox.com/docs/installation.html#system-requirements
.

Q: What network setups are supported between Proxmox Datacenter Manager and remotes?
A: In general the Proxmox Datacenter Manager needs to be able to connect to all Proxmox VE remotes directly to send API requests and query load and usage metrics. Remotes on the other hand do not need to be able to connect to Datacenter Manager directly. Reverse proxies between Proxmox Datacenter Manager and any of its Proxmox VE remotes are not supported, we recommend using tunneling (for example, WireGuard or OpenVPN) for hosts that must not be exposed directly to a non-private network.

Q: Where can I get more information about feature updates?
A: Check the
roadmap
,
forum
, the
mailing list
, and/or subscribe to our
newsletter
.

FAQ

Q: Can I upgrade the latest Proxmox Backup Server 3.x to 4.2 with apt?
A: Yes, please follow the upgrade instructions on https://pbs.proxmox.com/wiki/Upgrade_from_3_to_4

Q: How does this integrate into Proxmox Virtual Environment?
A: Just add a Proxmox Backup Server datastore as a new storage target in your Proxmox VE. Make sure that you run the latest Proxmox VE 9.x

Q: Is Proxmox Backup Server still compatible with older clients or Proxmox VE releases?
A: We are actively testing the compatibility of all the major versions currently supported, including the previous one. This means that you can safely back up from Proxmox VE 8 to Proxmox Backup Server 4, or from Proxmox VE 9 to Proxmox Backup Server 3. However, full compatibility with major client versions that are two or more releases apart, like for example Proxmox VE 7 based on Debian 11 Bullseye and Proxmox Backup Server 4 based on Debian 13 Trixie, is supported on a best-effort basis only.

Q: How long will Proxmox Backup Server 3.4 receive bug fixes and security support?
A: Proxmox Backup Server 3.4 will receive security updates and critical bug fixes until August 2026. This support window provides an overlap of approximately one year after the release of Proxmox Backup Server 4, giving users ample time to plan their upgrade to the new major version.
For more information on the support lifecycle of Proxmox Backup Server releases, please visit:
https://pbs.proxmox.com/docs/faq.html#how-long-will-my-proxmox-backup-server-version-be-supported

Q: How do I install the proxmox-backup-client on my Debian or Ubuntu server?
A: We provide a "Proxmox Backup Client-only Repository". See https://pbs.proxmox.com/docs/installation.html#client-installation
For Debian derivatives we recommend installing the proxmox-backup-client-static package to avoid issues with different system library versions.

Q: What will happen with the existing backup tool (vzdump) in Proxmox Virtual Environment?
A: You can still use vzdump. The new backup is an additional, but very powerful way to back up and restore your VMs and containers.

Q: Is there any recommended server hardware for the Proxmox Backup Server?
A: We recommend enterprise-grade server hardware components, with fast local SSD/NVMe storage. Access and response times from rotating drives will slow down all backup server operations. See https://pbs.proxmox.com/docs/installation.html#recommended-server-system-requirements

Q: Can I install Proxmox Backup Server on Debian, in a VM, as LXC or alongside with Proxmox VE?
A: Yes, but all this is not the recommended setup (expert use only).

Q: Where can I get more information about upcoming features?
A: Follow the announcement forum and pbs-devel mailing list https://lists.proxmox.com/postorius/lists/pbs-devel.lists.proxmox.com/ and subscribe to our newsletter https://www.proxmox.com/news and see https://pbs.proxmox.com/wiki/Roadmap.

• http://archive.proxmox.com/
• https://archive.proxmox.com/

To use the archive for an EOL release, you will need to change the domain in the apt repository configuration files in /etc/apt/sources.list or inside /etc/apt/sources.list.d/ from enterprise.proxmox.com or download.proxmox.com to archive.proxmox.com.

Some important technical details for this archive:

• HTTP Support: We explicitly provide unencrypted HTTP access. This is crucial for older releases, as their SSL/TLS stacks are generally not compatible with modern Let's Encrypt certificates found on HTTPS.
• Security: Please note that package repository integrity is protected by release files signed with a GPG key on a Hardware Security Module (HSM). This validation occurs independently of transport security, making the use of HTTP safe for these package updates.
• Enterprise Repositories: The enterprise repositories for these specific EOL versions are available on the archive host without subscription restrictions, as they are fully synchronized with the other repositories.
• Rate Limiting: The archive resides on separate CDN nodes and is rate-limited, please only use it if really necessary.

Future Changes to the Main Repository

With this new archive in place, we will be removing these older packages from our main CDN in the near future. This change allows us to reduce load on the main mirrors and ensures sufficient space for upcoming releases.
Moving forward, we plan to roughly follow Debian's archival schedule: keeping stable, oldstable, and oldoldstable on the main CDN, and moving everything older to the archive CDN. We also plan to migrate older ISO images and container appliances to this archive in the future.

Note: While this archive ensures continued access to older resources, please remember that these versions are End-of-Life. If you are still using them, we strongly recommend upgrading to a current, supported release as soon as possible.

Best regards,
Thomas

We're very excited to present the first stable release of our new Proxmox Datacenter Manager!

Proxmox Datacenter Manager is an open-source, centralized management solution to oversee and manage multiple, independent Proxmox-based environments. It provides an aggregated view of all your connected nodes and clusters and is designed to manage complex and distributed infrastructures, from local installations to globally scaled data centers. With multi-cluster management it enables management like live migrations of virtual guests without any cluster network requirements.

The project is fully developed in the Rust programming language, from the backend API server to the CLI tools to a completely new frontend. The frontend is built on the new widget toolkit that we developed over the last few years. This offers a more modern web user interface experience, not only in terms of appearance and functionality, but also in terms of accessibility, speed, and compatibility. Proxmox Datacenter Manager is licensed under the GNU Affero General Public License v3 (GNU AGPLv3).

A big THANK YOU to our global community for the substantial support during the beta phase! We are particularly grateful for the stress tests performed, the detailed bug reports, and contributions of other kinds - thank you so much, your collaboration is fantastic!

Main Features

• Based on Debian Trixie 13.2, with latest security updates
• Linux kernel based on version 6.17 with ZFS 2.3.4 included
• Authentication: support for LDAP, Active Directory and OpenID Connect realms for authentication
• Custom views for tailored overviews filtered by remotes, resources, resource type, or tags and dedicated access control
• Support for Proxmox Virtual Environment and Proxmox Backup Server remotes
• Efficient central metric collection
• Powerful search functionality to quickly find resources (filtered by resource type, status, or more).
• Privilege Management for Proxmox Datacenter Manager users from the access control UI
• Centralized system update overview
• Initial Software-Defined Networking integration with EVPN configuration between clusters
• Centralized update overview

FAQ

Q: How does this integrate into Proxmox Virtual Environment and Proxmox Backup Server?
A: You can add arbitrary Proxmox hosts or clusters as remotes. Proxmox Datacenter Manager will then monitor them and provide basic management using only the API.

Q: How many different Proxmox VE hosts and/or cluster can I manage with a single Datacenter Manager instance?
A: Due to the early stage of development, there are still some pain points, but we are confident that we will be able to handle large setups with a moderate amount of resources. We have run tests with over 5000 remotes and over 10000 virtual guests to confirm the performance expectations of our new UI framework. We are targeting similar numbers for the backend.

Q: What Proxmox VE and Proxmox Backup Server versions are supported?
A: The minimum required Proxmox VE version is 8.4 and the minimum required Proxmox Backup Server version is 3.4.
We will support all actively supported Proxmox project releases, but encourage frequent upgrades of both PDM and the PVE and PBS remotes to leverage all features.

Q: Can I upgrade a beta installation to the stable 1.0 via apt?
A: A: Yes, upgrading from is possible via apt and GUI. We recommend using the
pdm-enterprise repository
on upgrade for the most stable experience.

Q: Can I upgrade Proxmox Datacenter Manager Alpha to this 1.0 version?
A: Yes, please follow the upgrade instructions on
https://pve.proxmox.com/wiki/Proxmox_Datacenter_Manager_Upgrade_from_Alpha_to_1

Q: Can I install Proxmox Datacenter Manager alongside with Proxmox VE or Proxmox Backup Server?
A: Yes, but installing alongside other Proxmox projects is not the recommended setup (expert use only).

Q: What environment does Proxmox Datacenter Manager support?
A: Proxmox Datacenter Manager will work everywhere where a standard x86-64/AMD64 Debian system is supported.

Q: Is there any recommended system requirements for the Proxmox Datacenter Manager?
A: Yes, see
https://pdm.proxmox.com/docs/installation.html#system-requirements
.

Q: What network setups are supported between Proxmox Datacenter Manager and remotes?
A: In general the Proxmox Datacenter Manager needs to be able to connect to all Proxmox VE remotes directly to send API requests and query load and usage metrics. Remotes on the other hand do not need to be able to connect to Datacenter Manager directly. Reverse proxies between Proxmox Datacenter Manager and any of its Proxmox VE remotes are not supported, we recommend using tunneling (for example, WireGuard or OpenVPN) for hosts that must not be exposed directly to a non-private network.

Q: Where can I get more information about feature updates?
A: Check the
roadmap

forum
, the
mailing list
, and/or subscribe to our
newsletter
.

FAQ

Q: Can I upgrade the latest Proxmox Backup Server 3.x to 4.1 with apt?
A: Yes, please follow the upgrade instructions on https://pbs.proxmox.com/wiki/index.php/Upgrade_from_3_to_4

Q: How does this integrate into Proxmox Virtual Environment?
A: Just add a Proxmox Backup Server datastore as a new storage target in your Proxmox VE. Make sure that you run the latest Proxmox VE 9.x

Q: Is Proxmox Backup Server still compatible with older clients or Proxmox VE releases?
A: We are actively testing the compatibility of all the major versions currently supported, including the previous one. This means that you can safely back up from Proxmox VE 8 to Proxmox Backup Server 4, or from Proxmox VE 9 to Proxmox Backup Server 3. However, full compatibility with major client versions that are two or more releases apart, like for example Proxmox VE 7 based on Debian 11 Bullseye and Proxmox Backup Server 4 based on Debian 13 Trixie, is supported on a best-effort basis only.

Q: How long will Proxmox Backup Server 3.4 receive bug fixes and security support?
A: Proxmox Backup Server 3.4 will receive security updates and critical bug fixes until August 2026. This support window provides an overlap of approximately one year after the release of Proxmox Backup Server 4, giving users ample time to plan their upgrade to the new major version.
For more information on the support lifecycle of Proxmox Backup Server releases, please visit:
https://pbs.proxmox.com/docs/faq.html#how-long-will-my-proxmox-backup-server-version-be-supported

Q: How do I install the proxmox-backup-client on my Debian or Ubuntu server?
A: We provide a "Proxmox Backup Client-only Repository". See https://pbs.proxmox.com/docs/installation.html#client-installation
For Debian derivatives we recommend installing the proxmox-backup-client-static package to avoid issues with different system library versions.

Q: What will happen with the existing backup tool (vzdump) in Proxmox Virtual Environment?
A: You can still use vzdump. The new backup is an additional, but very powerful way to back up and restore your VMs and containers.

Q: Is there any recommended server hardware for the Proxmox Backup Server?
A: We recommend enterprise-grade server hardware components, with fast local SSD/NVMe storage. Access and response times from rotating drives will slow down all backup server operations. See https://pbs.proxmox.com/docs/installation.html#recommended-server-system-requirements

Q: Can I install Proxmox Backup Server on Debian, in a VM, as LXC or alongside with Proxmox VE?
A: Yes, but all this is not the recommended setup (expert use only).

Q: Where can I get more information about upcoming features?
A: Follow the announcement forum and pbs-devel mailing list https://lists.proxmox.com/cgi-bin/mailman/listinfo/pbs-devel, and subscribe to our newsletter https://www.proxmox.com/news and see https://pbs.proxmox.com/wiki/index.php/Roadmap.

Based on Debian Trixie (13.2)

• Latest 6.17.2-1 Kernel as new stable default
• QEMU 10.1.2
• LXC 6.0.5
• ZFS 2.3.4
• Ceph Squid 19.2.3

Highlights

• Create LXC containers from OCI images.
• Open Container Initiative (OCI) images are a popular format for distributing templates for system or application containers.
• OCI images can now be uploaded manually or downloaded from image registries, and then be used as templates for LXC containers.
• This allows to create full system containers from suitable OCI images.
• Initial support for creating application containers from suitable OCI images is also available (technology preview).
• Support for TPM state in qcow2 format.
• Some VM guest workloads require attaching a virtual Trusted Platform Module (TPM), for example newer Windows guests.
• The state of a virtual TPM can now be stored in the qcow2 format.
• This allows taking snapshots of VMs with a TPM state on file-level storages such as NFS or CIFS shares.
• Storages with "snapshots as volume chains" (technology preview) enabled now support taking offline snapshots of VMs with TPM state.
• Fine-grained control of nested virtualization for VM guests.
• Some VM guest workloads need access to the host CPU's virtualization extensions for nested virtualization.
• Examples are nested hypervisors or Windows guests with Virtualization-based Security enabled.
• A new vCPU flag allows to enable nested virtualization on top of a vCPU type that corresponds to the host CPU vendor and generation.
• This can be an alternative to using the full host vCPU type.
• More detailed status reporting for the Software-Defined Networking (SDN) stack in the GUI.
• Local bridges and VNets report the currently connected guests.
• EVPN zones additionally report the learned IPs and MAC addresses.
• Fabrics are now part of the resource tree and report routes, neighbors, and interfaces.

Kernel 6.17 as new stable default

• Seamless upgrade from Proxmox VE 8.4, see Upgrade from 8 to 9.
