Absolutely, very good point.
There's a few places where we return the current running state rather
than the initial configuration we provided, but this would be a
particularly bad case.
It's a bit fugly, though - should libvirt do ListDomains(),
GetBridgName() and match the bridge name, or should we have
virNetworkLookupByBridge() and make qemud do the lookup itself?
