I'm in the process of building a second ovirt cluster within the default DC. This new cluster will use the same storage domains as the original cluster, and I will slowly migrate VMs from the old cluster to the new.

Given that the old and new cluster hosts have a firewall between them I need to ensure that all relevant ports are open, with particular attention to the correct operation of SPM.

Is it sufficient to open TCP ports 16514 and 54321 to achieve this?

Thanks,

Alan
