Hi
I'm trying to run VM using libvirt.xml file and getting following error...
virsh start instance-00000003
error: Failed to start domain instance-00000003 error: internal error Process exited while reading console log output: failed to launch bridge helper kvm: -netdev bridge,br=qbr1f2191ce-38,id=hostnet0: Device 'bridge' could not be initialized

2) it looks like this config was generated by OpenStack. Why are you starting it via virsh? I don't use OpenStack myself, but am assuming that a lot of the objects referenced in an OpenStack-generated libvirt domain config are auto-created by some piece of OpenStack code just prior to starting the domain. For example, the bridge device (there is a separate bridge device created per guest interface) and the filter that is applied to that interface (likewise). I was of the impression that OpenStack instances needed to be started from some sort of OpenStack management app, *not* from virsh.
Yes, it's not recommended to start Nova instances behind its back using Libvirt/virsh. -- /kashyap
