Enterprise virtualization has been closely tied to Intel and AMD processors for decades. However, the rapid growth of Artificial Intelligence, high-performance computing (HPC), and the push for greater energy efficiency in data centers are driving interest in new processor architectures. Against this backdrop, Proxmox VE 9.2 introduces official support for ARM64 (AArch64), marking a significant milestone for one of the most widely adopted open-source virtualization platforms.
For organizations already using Proxmox VE or evaluating alternatives to VMware, this does not mean they need to migrate to ARM servers immediately. The real significance is that Proxmox has evolved into a virtualization platform officially capable of supporting both x86-64 and ARM64 infrastructures, aligning itself with a market that is steadily becoming more diverse.
Proxmox VE for ARM64 in 20 Seconds
- Proxmox VE 9.2 introduces official support for the ARM64 (AArch64) architecture.
- It shares the same codebase, documentation, repositories, and support lifecycle as the x86-64 edition.
- At launch, two platforms are officially certified: NVIDIA Grace Hopper and NVIDIA Vera.
- Support is designed for enterprise servers, not development boards such as the Raspberry Pi.
- ARM64 support positions Proxmox for future cloud, Artificial Intelligence, and HPC deployments.
This release does not change Proxmox’s core philosophy. It remains an open-source virtualization platform built around technologies such as KVM and LXC, offering high availability, clustering, software-defined storage, backup capabilities, and centralized management. These features have made it an increasingly attractive choice for organizations looking to reduce dependence on proprietary virtualization platforms.
From Community Builds to Official Support
Until now, it was possible to run Proxmox on certain ARM systems through community-maintained projects. While valuable for testing and laboratory environments, these unofficial builds came with clear limitations: they followed separate development cycles, required additional maintenance, and lacked official support.
With Proxmox VE 9.2, that changes completely.
ARM64 is no longer a side project. It is now part of the main Proxmox codebase, receiving the same level of attention as the traditional x86-64 version.
That includes:
- Enterprise repositories;
- Official updates;
- Commercial support;
- Unified documentation;
- The same release and maintenance schedule.
For system administrators, this means they can manage both architectures using virtually the same tools, workflows, and operational experience.
The ARM edition also shares the same technology stack as the x86 version:
- Debian 13.5 “Trixie”;
- Linux Kernel 7.0;
- QEMU 11;
- LXC 7;
- ZFS 2.4.
The familiar web interface, REST API, command-line tools, storage management, clustering capabilities, and most of the documentation remain unchanged.
Which Hardware Is Officially Supported?
One of the most significant aspects of this announcement is that Proxmox now publishes an official list of supported ARM platforms for the first time.
At launch, the certified systems are:
- NVIDIA Grace Hopper
- NVIDIA Vera
This is far from accidental.
NVIDIA’s Grace processors are becoming key components in next-generation Artificial Intelligence and HPC infrastructures, combining high-core-count ARM CPUs with tight integration alongside NVIDIA GPUs. They are increasingly being deployed in AI training, inference, scientific computing, and supercomputing environments.
Proxmox also states that it is working with additional hardware vendors to expand the list of supported ARM platforms in future releases, suggesting that the enterprise ARM ecosystem will continue to grow.
Not Every ARM Device Can Run Proxmox
One common misconception following the announcement is that Proxmox can now be installed on any ARM-based device.
That is not the case.
Official support targets enterprise-class servers, not low-cost development boards.
Current requirements include:
- UEFI boot support;
- ACPI-based hardware description;
- ARMv9-A processors, while ARMv8-A is supported on a best-effort basis.
As a result, popular boards such as the Raspberry Pi, Orange Pi, RockPro, and most Device Tree-based single-board computers are not officially supported.
Proxmox continues to focus on enterprise infrastructure and professional data center deployments.
How Does It Differ from the x86 Version?
From an operational perspective, the experience is almost identical.
However, some architectural differences remain.
Among the most important:
- Virtual machines boot exclusively through UEFI using AAVMF;
- SeaBIOS is not available;
- Intel- and AMD-specific technologies such as Intel GVT-g and AMD SEV remain exclusive to x86 platforms;
- Virtual machines can only run on hosts using the same processor architecture;
- Live migration between ARM and x86 hosts is not supported.
In other words, ARM servers are not drop-in replacements for existing x86 clusters. Each architecture maintains its own capabilities and limitations, even though both can be managed through the same Proxmox interface.
A Sign of Where Enterprise Infrastructure Is Heading
Beyond the technical announcement, this release reflects a broader industry trend.
For many years, enterprise data centers relied almost exclusively on x86 processors. Today, the rise of Artificial Intelligence workloads, increasing energy costs, and the search for better performance per watt are accelerating the adoption of ARM-based server processors.
Major cloud providers already offer ARM-based instances for selected workloads, while companies such as NVIDIA are investing heavily in ARM-powered AI and supercomputing platforms.
In this context, having a virtualization platform that officially supports multiple processor architectures reduces operational complexity and gives organizations greater flexibility as new hardware becomes available.
What This Means for Organizations Using Proxmox
For most businesses, this announcement does not require an immediate infrastructure change.
The overwhelming majority of enterprise virtualization deployments continue to run on x86 servers, a mature ecosystem with broad hardware compatibility and decades of software optimization.
However, official ARM64 support provides an important level of future readiness. Organizations that standardize on Proxmox VE can be confident that their virtualization platform will evolve alongside the market, without forcing them to adopt a different hypervisor if ARM servers become attractive for specific workloads in the future.
At Stackscale, we continue to provide private cloud, bare-metal servers, and managed Proxmox VE platforms based on enterprise-class x86 hardware, which remains the best fit for the vast majority of production environments today. Nevertheless, official ARM64 support highlights the flexibility of the Proxmox ecosystem and reinforces its position as an open virtualization platform capable of adapting to the next generation of enterprise infrastructure.
As heterogeneous data centers become more common, where multiple processor architectures coexist depending on workload requirements, having a virtualization platform prepared for that evolution may become an increasingly valuable advantage.
Frequently Asked Questions
Is Proxmox VE for ARM64 an experimental release?
No. ARM64 is officially supported starting with Proxmox VE 9.2 and follows the same development, update, and commercial support lifecycle as the x86-64 edition.
Which ARM servers are officially supported?
At launch, Proxmox officially certifies NVIDIA Grace Hopper and NVIDIA Vera. Additional enterprise ARM platforms are expected to be added over time.
Can I install Proxmox VE on a Raspberry Pi?
No. Official support requires servers that implement UEFI and ACPI. Most development boards, including Raspberry Pi, rely on Device Tree and are therefore not supported.
Does this mean organizations should migrate to ARM now?
Not necessarily. Most enterprise virtualization environments continue to rely on x86 servers. ARM64 support simply ensures that Proxmox is ready as enterprise ARM adoption continues to grow.
Could Stackscale offer Proxmox on ARM in the future?
Today, Stackscale provides Proxmox VE platforms on high-performance x86 enterprise servers. Official ARM64 support expands the possibilities of the Proxmox ecosystem and creates opportunities to evaluate ARM-based infrastructure as enterprise hardware matures and adoption increases.
