Description of problem:
After rebooting a compute node the OVS is connected to the all the controllers but the pseudo agent is down.
In Neutron log:

Please add these to the karaf logging configuration and post the resultant karaf.log.
log4j2.logger.itzik.name = org.opendaylight.neutron.hostconfig.ovs.NeutronHostconfigOvsListener
log4j2.logger.itzik.level = DEBUG
Itzik and I sat on this today. What we saw was that indeed, the rebooted host is missing from /operational/neutron:neutron/hostconfigs. We also saw that the node was missing from /operational/network-topology:network-topology/ which seems to indicate that ovsdb plugin is failing to write that node to operational. This requires some additional digging.

Restarting the OVS on the compute node - no problem
Power down the compute , waiting for 10 minutes and powering it on - no problem.
