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.
