Looking at

It seems that a change in vdsm/libvirt exposed NFS configuration issue, that may was

needed in the past and probably not needed now.

If you use NFS, I would like to see your /etc/exports (after sanitizing it if needed).

For extra bonus, output of "exportfs -v" would be useful.

In particular, I want to know if you use root_squash, all_squash, or no_root_squash.

Thanks,
