Hi,

I have ovs configured as under:

$ sudo ovs-vsctl show
8fb49ade-7e69-4bec-bac6-1c55f41ed1be
   Bridge "br0"
       Controller "tcp:192.168.100.20:6653"
           is_connected: true
       Port "br0"
           Interface "br0"
               type: internal
   ovs_version: "2.6.90"

Now when i restart ovs as
$sudo /etc/init.d/openvswitch-switch restart

The odl connectivity fails.

$ sudo ovs-vsctl show
8fb49ade-7e69-4bec-bac6-1c55f41ed1be
   Bridge "br0"
       Controller "tcp:192.168.100.20:6653"
       Port "br0"
           Interface "br0"
               type: internal
   ovs_version: "2.6.90"
