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?
