Hi,
I had the same problem. I found a solution in RDO Openstack forum. link: http://openstack.redhat.com/forum/discussion/comment/561#Comment_561 1) stop quantum services and remove ports from ovs. # ovs-vsctl del-port br-int xxxxx # ovs-vsctl del-port br-ext xxxxx It's cleaned up as: # ovs-vsctl show 394e8a6b-a5e0-4fef-8f8f-506889aebfc1 Bridge br-int Port br-int Interface br-int type: internal Bridge br-ex Port br-ex Interface br-ex type: internal Port "eth0" Interface "eth0" ovs_version: "1.10.0" 2) add ovs_use_veth = True in l3_agent.ini, dhcp_agent.ini and lbaas_agent.ini.
