You are aware that you're trying to ride an arguably dead horse to new frontiers,
right?
I'm trying somethings similar with Proxmox on ARM using an Orange PI 5+ and a
Raspberry Pi5, where nearly everything works, except live migration.
But there is a lot of things that are still missing in QEMU and KVM for ARM to support
multi-host orchestration, so you may want to adjust your expectations.
