I don't understand your reply, since its not clear to me which modules you are mentioning in various spots (bridge?  openvswitch_mod? NOVA?) and things seem to run correctly at times, but not others.  Did you follow the steps exactly as I mentioned?  Including using Open vSwitch 1.1.1?

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.
