Thank you! I decided to go with a RHEL 8 host, which worked perfectly fine. But that brings me to a new question, for which I'll start a new thread.

It may be he issue describe here: https://github.com/oVirt/ovirt-site/pull/2433 The fix is to change this on the serve side: # grep RPCMOUNTDOPTS /etc/default/nfs-kernel-server # --manage-gids is not compatible with oVirt. #RPCMOUNTDOPTS="--manage-gids" RPCMOUNTDOPTS="" > It appears I'm running into the issue described in this thread: > https://lists.ovirt.org/archives/list/users@ovirt.org/thread/BNVXUH5B26FBFCGYLG62JUSB5SOU2MN7/#IZTU744GVKY5OJT4QOULLZVKGYADXDOO > ...

To verify your suspicion , temporarily run 'setenforce 0' on the nodes in the cluster and try again to attach the NFS (via oVirt of course). If it works, then you can check /var/log/audit/audit log for AVC entries (or just run 'sealert -a ' )It will tell you what kind of label you will need.Then you can just change in oVirt the mount options and append 'context= and it will work. I remember another issue related to some ubuntu NFS server options, but I can't recall it right now.
