Broker is broken or down. Check the status of ovirt-ha-broker service.

This is another piece that points to broker or storage issues. Agent
collects local data and then publishes them to other nodes through
broker. So it is possible for the agent to know the status of the VM
locally, but not be able to publish it.

hosted-engine command line tool then reads the synchronization
whiteboard too, but it does not see anything that was not published
and ends up reporting stale data.

Please check the services.

Best regards
