[openstack-dev] [networking-ovn] restart failure to bring up ovn services

Following the docs online (Newton), the installation was successful.
However when the VM that has the controller (and ovn-nb) restarted, it
fails to bring up ovs & ovn. This is ubuntu deployment using
python-networking-ovn and locally built ovn. Is this a deployment problem?
Is it possible to recover from here without losing the neutron DB sync? I
have not configured any networks that I need to save.
NOTE: I did a reboot once before and the services came back fine at that
time. Not sure if there is a sequence to be followed while shutting down -
if so can I know what it would be?
