This is not required at all. Are you sure that your cluster is not set in global maintenance mode? Can you please share /var/log/ovirt-hosted-engine-ha/agent.log and broker.log from your hosts? > This does work, but it takes a very long time, and it usually starts up on > any node other than the one I told it to start on. > > So I guess two (or three) questions.
