It worked well enough for osstest to start a guest with its usual
config, with the libvirt bugfix I sent out a few hours ago.

But the whole point of the tests is to find bugs, so I don't see the
fact that this may or may not be buggy as a reason for osstest not to
use it. If that shows that it is buggy then we should fix it.
