[ovs-discuss] Controller Connection openvswitch

Echoing what Ben said, the issue will certainly be on the controller or
configuration issue with the fabric the control channel is on (loops etc).
I would forward the email along with logs from the OSGI console or the
/logging directory to controller-dev at lists.opendaylight.org

Alternatively you can pop into #opendaylight (controller/overall channel)
or #opendaylight-ovsdb (ODL OVSDB plugin) channel for a realtime assist.

Thanks,
-Brent
