Proxmox VE 9.2 Adds Official arm64 Support with Full Support for NVIDIA Grace Hopper and Vera
Proxmox has released Proxmox VE 9.2, introducing official support for 64-bit ARM architecture (arm64/aarch64) for the first time. Previously, Proxmox VE was officially available only for x86-64 (amd64). With the new release, arm64 builds share the same code base, package repositories, and release lifecycle as the x86-64 version.
Proxmox VE 9.2 for arm64 is based on Debian 13.5 “Trixie” and uses Linux kernel 7.0 as the stable default. It includes the same core virtualization technologies available on x86-64, including QEMU 11.0, LXC 7.0, and ZFS 2.4. Configuration, management tools, and documentation remain consistent across both architectures, apart from a limited number of architecture-specific differences.
Platform Support
Full official support for arm64 is currently limited to the NVIDIA Grace Hopper and NVIDIA Vera platforms. Other UEFI-based ARMv9-A and newer server hardware receives best-effort support, while ARMv8-A systems can also operate under the same best-effort conditions.
The host system must boot using UEFI and describe its hardware through ACPI. This requirement excludes systems that rely exclusively on device trees for hardware description.
Raspberry Pi and ARM Single-Board Computers
Proxmox has confirmed that Raspberry Pi and similar single-board computers are not officially supported. The arm64 ISO installer requires UEFI boot and ACPI hardware description, while Raspberry Pi systems typically rely on device trees and therefore do not meet the standard installation requirements.
However, Proxmox VE can still be run on Raspberry Pi systems through unofficial methods. One option is to install it manually on top of a fresh Raspberry Pi OS Trixie installation. Another is to configure the Raspberry Pi for UEFI boot. Both approaches can work, but they remain outside Proxmox's officially supported hardware list.
Architecture-Specific Differences
On arm64, virtual machines boot through the ARM version of OVMF (AAVMF), while SeaBIOS is not available. Some features remain exclusive to x86, including AMD SEV memory encryption and Intel GVT-g mediated vGPUs.
ARM systems also do not use an OS-level CPU microcode package equivalent to the Intel and AMD microcode packages available on x86. Virtual machines can run only on nodes using the same CPU architecture, and live migration is limited to nodes with matching architectures.
Mixed x86-64/arm64 clusters are not officially supported. Moving a virtual machine between architectures requires offline migration, backup and restore, or shared storage, followed by the necessary reinstallation or reconfiguration on the destination system.
Enterprise Support
Proxmox emphasizes that arm64 support is not a technology preview. The arm64 version follows the same release lifecycle and support periods as the x86-64 version.
The pve-enterprise repository is available for arm64, and customers with an active subscription receive enterprise support at the same service levels available for x86-64. Arm64 subscriptions are handled separately from x86-64 subscriptions and are currently available upon request through the Proxmox sales team.
Proxmox credits NVIDIA for its collaboration in developing and validating the arm64 port. The company says the platform is already running in production on supported hardware and that it has also validated systems together with Supermicro.
The company also reports that ZFS and Ceph achieve feature and performance parity with existing x86 deployments. This is particularly relevant for organizations using Proxmox as a virtualization and storage platform, where storage capabilities can be more important than the underlying CPU architecture.
According to Thomas Lamprecht, CTO at Proxmox, developing directly on NVIDIA Grace Hopper systems allowed the company to validate the platform on production-class hardware from the beginning.
Proxmox is continuing to work with additional enterprise server manufacturers and expects the list of officially supported ARM platforms to grow over time. The development also follows Proxmox VE joining the NVIDIA Mission Control ecosystem as the high-availability layer for AI factories.
Internal test builds for other Proxmox products, including Proxmox Backup Server, are also underway. Proxmox says the prioritization of these efforts will depend on demand from enterprise customers.
