So I tried a few tests with different CPU models and it works as
expected.  One minor caveat is that using "host" has side effects
in some cases, causing tests to fail because they may also require
KVM to be enabled.

But this is a generic mechanism so I don't think it should be
concerned with that.

Only thing is: can we please just break this line (I could not ignore
a 174 character line :).

With the line broken mentioned above (which I can take care of when
queueing this patch):
