Jiri,
I have an unrelated concern regarding the semantics of comparison of
host and guest CPUs.
I do not compare CPUs for fun, but rather to know if a guest can be run
on a specific host. However, this is not exactly what
virConnectCompareCPU gives me: A vmx-enabled host cpu is a superset of

When a CPU to be compared with host CPU describes a host CPU instead of
a guest CPU, the result is incorrect. This is because instead of
treating additional features in host CPU description as required, they
were treated as if they were mentioned with all possible policies at the
same time.
