Hello, Can you send us dumpxml of the VM started in both ways. Maybe there are parameters automatically added by the VMM application we are not aware, like the network device emulation. It could also happen that that the bridge it is attached is not correct (sorry for this vague error description) and net driver calls to it don't work.
