[TEST] Fix calls to virsh to handle potiential extra debug messages from virsh
Occasionally, virsh will return additional debug or error messages. This
change makes it so our virsh command only returns stdout. We don't care about
the output of stderr, so might as well drop it. That way, it doesn't
interfere when we parse the output.
