Sorry for the delay. I've been experiencing issues with the mail server :(

At first glance, this message makes me think that this function is for "comparing two hypervisor CPUs".
Perhaps the message should say "comparing with the hypervisor CPU is not supported for arch %s" instead?
I think that makes it more clear that the other CPU in question is not (necessarily) a hypervisor CPU.
