I had been successfully using OVS in VLAN mode. I reset my core_plugin and service_plugins in neutron.conf, I followed the steps to reinitialize my Neutron databases, to upgrade their heads with neutron-db-manage, and transpose my configuration from /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini to /etc/neutron/plugins/ml2/ml2_conf.ini. My neutron agent-list seems happy:</div><div><br></div><div><font face="Courier"># neutron
