thanks, in fact it doesn't seem to be the issue.  Only the debugging
message prints it as VIR_DOMAIN_NOSTATE, while the rest of the code
considers it as VIR_DOMAIN_RUNNING.  Something else is going on, as
calling virDomainInfo twice, "fix" the problem, and that is why
re-enabling polling fix the issue.  I will look more into it.
