OK, thanks for the advice, I just updated my environment to use Xen 4.1.1 and libvirt.
I've changed the SQL DB table nova.networks to use the bridge xenbr0 instead of br100, but when I try to start an instance, the cloud controller's nova-compute gives me an error searching for br100, and the instance is frozen in the networking phase: (nova): TRACE: NotFound: No network for bridge br100 I already restarted all nova-computes, is there anywhere else I should change the bridge name to xenbr0? I only have one network configured in nova.networks and it is using xenbr0 as bridge.
