That isn't visible to qemu though as cpu virtualization is handled by
the xen hypervisor.

I wouldn't do it that way for the reason outlined above, but it is an
option, yes.

Yep, sort of. And some plumbing for xenbus for guests with pv-on-hvm

Glauber Costa is working on a nice abstraction layer for qemu
