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 <log>' )It will tell you what kind of label you will need.Then you can just change in oVirt the mount options and append 'context=<selinux context> and it will work. I remember another issue related to some ubuntu NFS server options, but I can't recall it right now.

I got to the point of actually adding the new Storage Domain. When I click OK, I see the storage domain appear momentarily before disappearing, at which point I get a message about oVirt not being able to obtain a lock. It appears I'm running into the issue described in this thread: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/BNVXUH5B26FBFCG... ... Although the actual export is ext4, not xfs. From what I'm reading on that thread and elsewhere, it sounds like this problem is a result of SELinux not being present, is that correct? Is my only option here to install an OS that supports SELinux?
