Since the enum virDomainState is part of our public API, I'm not worried
about the numbers ever being tied to the wrong state.  But wouldn't it
be nicer for the XML to use a string conversion of a name, rather than
just a raw number?  On the other hand, this is just for testing
purposes, so I can live with it.

Should we also reject VIR_DOMAIN_NOSTATE?

Maybe s/write only/input only/

ACK, but not until after the release.
