Your neutron linuxbridge agent is failing to communicate with the neutron server over RPC, so vif plugging (on the compute host) is failing. Check the RPC configuration between the neutron linuxbridge agent and the server and make sure the agent is reporting in (I think there is a neutron services or agents command or something to make sure it's "up"). -- Thanks, Matt
