Are you sure that the bridge module isn't loaded when ovs-vswitchd starts? If restarting ovs-vswitchd and ovs-brcompatd don't fix the problem, then try bringing down your OVS daemons (ovsdb-server, ovs-vswitchd, and ovs-brcompatd), deleting your OVS database (often in "/etc/openvswitch/conf.db"), and restarting them all. This should bring things back to a clean state. Then try rerunning your NOVA init scripts. Please make sure that you're running OVS 1.1.1 and the bridge module is not loaded before following these steps.
