Proxmox ‘host doesn’t support requested feature’ creating Ubuntu 24.04 guest

I’m getting these errors when creating a new Ubuntu 24.04 guest on my Proxmox server:

kvm: warning: host doesn't support requested feature: CPUID.01H:ECX.sse4.2

From this post, it suggests changing the host to kvm64 to emulate unsupported cpu hardware features on the host (an older MacPro 3,1). Fixed.
