Proxmox VE 9.2 shipped this month with official ARM64 support, the first time the project has supported anything other than x86-64. If your first thought was “finally, Proxmox on a Raspberry Pi,” it isn’t that. The Pi is specifically not supported, and the reason is worth understanding.
What actually shipped
Same codebase as the x86-64 build, same package repositories, same release lifecycle. Debian 13.5 “Trixie” underneath, Linux 7.0, QEMU 11.0, LXC 7.0, ZFS 2.4. Full feature parity across KVM, LXC, ZFS, and Ceph.
This isn’t a side project or a community port. It’s the same product on a different architecture, which is a meaningfully different thing to commit to maintaining.
Why not the Pi
Proxmox requires the host to boot through UEFI and describe its hardware through ACPI. The Raspberry Pi, and most cheap ARM single-board computers, use device tree instead. That’s a static hardware description compiled into the boot process rather than a firmware interface the OS can query at runtime.
A hypervisor needs to enumerate and allocate hardware dynamically, so this isn’t arbitrary gatekeeping. It’s just that the SBC world mostly standardized on something a hypervisor can’t work with.
Day-one full support is NVIDIA Grace and NVIDIA Vera. Everything else UEFI-based on Armv8-A or Armv9-A gets best-effort.
Where that leaves a homelab
NVIDIA Grace hardware is not what most people have in a closet. So for now this is mostly interesting for what it signals rather than what you can immediately run.
ARM server hardware that boots UEFI properly does exist and keeps getting cheaper. Ampere-based systems, various rack ARM boxes. Proxmox committing to the architecture with the same lifecycle as its x86 build means that when the hardware becomes affordable, the hypervisor is already there and already supported.
Worth noting what you give up: AMD SEV and Intel GVT-g are x86-specific and don’t exist here. If you’re doing GPU mediation or memory encryption, that matters.
Nothing to do about this today unless you happen to own Grace hardware. Worth knowing it exists for the next time you’re pricing out a build and ARM looks tempting.
