If you want "hyperscale" in your homelab, the bare metal hypervisor needs to be x86-64 because unless you literally work for Amazon or a few others you are unlikely to be able to purchase other competitively priced and speedy arm based servers. There is still near zero availability in mass market for CPUs you can stick into motherboards from one of the top ten taiwanese vendors of serious server class motherboards. And don't even get me started on the lack of ability to actually buy raspberry pi of your desired configuration at a reasonable price and in stock to hit add to cart.
