(Get the code!)
The neutron code does make some attempts to monitor the state of openvswitch - a restart of the ovs database process should be detected by the agent, and appropriate action taken.
Having the agent detect and respond to the status of openvswitch and the flows its managing should be the right approach to dealing with this situation; I believe that this part of the codebase has improved since Icehouse, so we'll take a look, do some testing and see whether there are some cherry-picks we can make for Icehouse to improve resilience.
