Yeah I think for something like this the only people who will use it are
capable of getting the domain state numbers, and it keeps the code simpler.

But isn't it a valid state? I know xen used to return it quite a bit but that
was ages ago. But if any libvirt version returned it then it's useful for apps
to test.

Thanks, pushed now with that change.
