Since http://git.openstack.org/cgit/openstack/neutron/commit/?id=bd734811753a99d61e30998c734e465a8d507b8f , bridge_mapping" needs to be set to something useful. If only physical_interface_mappings in /etc/neutron/plugins/ml2/linuxbridge_agent.ini is set, it leads to the following error in the linuxbridge_agent.log :
