[libvirt] domain.info() sometimes returns state zero for running machines

[Andreas Sommer]

I'm using Xen-3.2-1 on Debian 5.0.1-lenny and retrieve information about 
running domains using

domain.info()[0]

The domain object is retrieved via connection.lookupByUUIDString(...) 
and stored as a variable called "domain". Usually the running domains 
have the state 1 (VIR_DOMAIN_RUNNING) or 2 (VIR_DOMAIN_BLOCKED), but 
sometimes it happens that 0 (VIR_DOMAIN_NOSTATE) is returned.
Why does that happen? I don't think it is an error because then it 
would've raised an exception...

Regards
 Andreas
