Symptoms

The OVM Cluster does not appear to have a running Master Server.

e.g. When the following command is ran on an OVS server, the is_master is returned as false on all OVS servers in the cluster, rather than true on the server in the Master Server role.

[root@hostname ~]# ovs-agent-db dump_db -c server_pool_servers | grep is_master
{'ovm1': {'is_master': False,
'ovm2': {'is_master': False,
'ovm3': {'is_master': False,
'ovm4': {'is_master': False,

The Oracle VM cluster does need to have a master server set, as that is how the Oracle VM Manager communicates with the Oracle VM servers.
