Proxmox VE now officially supports Arm, and for anyone running Arm-based homelab hardware this is a properly significant moment. Jeff Geerling has written up the details, including the caveats you need to know before diving in.

Up until now, running Proxmox on Arm has meant community ports, manual kernel wrangling, and the nagging worry that an update could break everything. Official support changes the game — you get proper repos, tested packages, and a upgrade path that doesn't rely on forum threads from 2023.

Why homelabbers should care

Arm hardware has quietly become a serious homelab option. Raspberry Pi 5 clusters, Ampere Altra boards on eBay, and mini PCs like the Orange Pi 5 Plus all offer decent compute at low power draw. Proxmox on Arm means you can run a proper hypervisor stack — VMs, containers, clustering, backups — on kit that sips 10–30W from the wall.

If you've been eyeing an efficient, quiet virtualisation node without the fan noise and leccy bills of an old Xeon, this opens the door.

The caveats

Jeff flags some real limitations. Not every feature has full parity with x86 yet — GPU passthrough support is limited, and some storage backends may need extra attention. Driver availability on Arm is still patchy compared to the mature x86 ecosystem. And if you're running niche ISOs that only ship x86 builds, you'll still need an x86 node in the mix.

It's also worth noting that "official support" doesn't mean "battle-tested in production for years." Treat it as solid but young — fine for a homelab, maybe not your business-critical stack just yet.

What to do

If you've got a Pi 5 or Arm SBC gathering dust, now's the time to flash a fresh Proxmox ISO and have a play. You'll want a decent boot drive — a USB SSD enclosure like our M.2 NVMe SSD Enclosure – USB-C 10Gbps with Magnetic Closure keeps things tidy for SBC setups where there's no internal NVMe slot.
