I was unable to catch up with the libvirt folks about this issue. 
However, we can handle this with the providers (instead of using the 
libvirt API call directly).

I'd consider this test an XFAIL in the KVM case.

This is an issue I addressed in a patch I sent out last week.  I need to 
make some modifications to that patch still.  So this one is a provider bug.
