Dear All,

We were able to solve the issue. The problem was after the reboot rabbitmq
is overloaded because ceilometer started after the reboot which was in
stopped state. Due to this the controller nodes resource utilization was
very high and cpu cores maxed out. As a result we got timeouts in our
neutron and rabbitmq logs. We stopped the ceilometer components both on
controllers and compute nodes, cleaned the ceilometer queues from rabbitmq,
emptied the ovsdb and restarted the neutron components in all the
controllers. Then slowly all the tags in ports are recovered and VM's are
reachable.
