I read “Proxmox for Arm64” and immediately thought about the Pi bolted behind my nav station. Then I read the hardware list: Nvidia Grace and Vera. Grace Hopper systems start around 40,000 euros for a 2U box, and full Vera Rubin racks are being guessed at 5 to 9 million dollars. That is not a boat build. That is a datacenter.
The useful detail for anyone like me is why. Proxmox says the Arm64 build should run on ARMv8-A too, as long as the system is configured with ACPI and UEFI. Most SBCs aren’t — they boot off a device tree that has to be hand-tuned per board. Arm VMs here boot only via UEFI, using AAVMF. So the blocker isn’t the CPU, it’s the firmware story.
What I’d actually do: don’t wait. If you want to poke at it, a Radxa Orion O6 is a few hundred dollars if you can find one, or rent an AWS Graviton4 instance from about 3 dollars an hour. My Apple hardware is out — the M4 uses iBoot, not native UEFI. And the Pi? Someone will get there. Meanwhile my boat keeps running plain Debian containers, which was always the honest answer.
The story — Vienna-based Proxmox Server Solutions released an officially supported Arm64 build of Proxmox VE 9.2, built on Debian 13.5 “Trixie” with Linux kernel 7.0, QEMU 11.0, LXC 7.0, OpenZFS 2.4 and Ceph Tentacle 20.2.3, putting it roughly level with the x86 version apart from SeaBIOS, AMD SEV, Intel GVT-g and cross-platform live migration. Official support targets Nvidia Grace and Vera systems, developed with Nvidia and Supermicro and validated on Grace Hopper. It’s free to download now, with a Backup Server for Arm64 promised shortly and subscription prices on request. (Source)
