<DIV dir=ltr>Hi,<BR><BR><BR>I had the same problem. I found a solution in RDO
Openstack forum.<BR>link:
http://openstack.redhat.com/forum/discussion/comment/561#Comment_561<BR><BR>1)
stop quantum services and remove ports from ovs.<BR><PRE><CODE># ovs-vsctl del-port br-int xxxxx
# ovs-vsctl del-port br-ext xxxxx
</CODE></PRE>It's cleaned up as:<BR><PRE><CODE># 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"
</CODE></PRE>2) add ovs_use_veth = True in l3_agent.ini, dhcp_agent.ini and
lbaas_agent.ini.<BR><BR><BR>
