This was necessary, but guys you got the memo too late
Q: Can I run Proxmox VE on a Raspberry Pi or a similar single-board computer? A: No. An arm64 host must boot through UEFI and describe its hardware through ACPI. Device-tree-only boards and legacy boot are not supported.
Basically no consumer facing arm SBCs, NAS boxes, etc will work with this. Frankly, I see this as a good thing though: Maybe it'll make the SBC market get its stuff together and start actually doing UEFI instead of every board needing a custom build.
I'm adding more details in my blog post here: https://www.jeffgeerling.com/blog/2026/proxmox-ve-arm-offici...
I don’t see why it couldn’t work, since Debian runs fine on these SBCs.
Maybe they mean there’s no enterprise support, but it technically runs?
