[Users] (potential bug) After I create a virtual disk I am unable to start a VM - Permissions issue ? The node seems to have no write access to the directory on the NFS server...

[Dominic Kaiser]

I had the same problem a month ago on a openfiler(fedora) system not a
debian system.  It was a file permissions error there was one folder that
permissions where not applied to correctly. It took me awhile I could not
determine if it was an ovirt error.  I use all nfs at the moment and have
installed two more nodes for data with no issue.  One of them is a debian
system called mediavault.  The folder that had a problem did not have vdsm
permissions it was another user I believe.  I had to manually edit as root.
