See `Can I mix x86-64 and arm64 nodes in one cluster?` in the Q&A section, I assume to get around the different arch problem, you could use Affinity Rules to let VMs only HA between same architecture.
This is awesome news! Just manually installed it on Pi5, and working great, sadly not sure a 8GB Pi is quite enough memory, but was a nice POC.

Detected nodes:
virt-1 | 10.11.17.11 | x86-64-v4
virt-2 | 10.11.17.12 | x86-64-v4
virt-3 | 10.11.17.13 | x86-64-v4
Cluster CPU type: x86-64-v4
Good point with the nested virt but that would probably break the VBS security stuff sadly, I think...
I have a Gold 6248R, which if I run `/usr/lib64/ld-linux-x86-64.so.2 --help` returns supported for x86-64-v4, but when I tried using it in 2025 and I think 2022, it crashes lockups. Not sure if there's a upcoming fix for the issue from qemu or...
