Comment 3 for bug 1327294

I'm curious if those of you seeing this are actually getting your /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini files passed as --config-file arguments to the OVS agent and neutron server. There's a known bug with Ubuntu's packaging that may cause those files to be ignored or for ml2 config files to passed even if ml2 isn't being used. Do a "ps auwx|grep neutron" to see what --config-file arguments are being used. If you don't see ovs_neutron_plugin.ini in the list, restart the neutron server and ovs agent services manually, adding "--config-file /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini" to the command line. Then retest and see if your GRE tunnels are set up properly.
