Polite ping. I'd like to at least make sure these patches are on the
right track with what libvirt expects for these commands. :)

s390x can report that the first model (A) is a subset of the second
(B). If A is the hypervisor CPU and a subset of B (the CPU contained
in the XML), then B would not be able to run on this machine and thus
we will report that CPU model B is incompatible.
