Could someone explain why oVirt is even requiring ownership of the iso images by
a specific user and group?  Isn't it enough to just require read/write
permissions on the export?  The file ownership requirement is causing us
problems because we have an NFSv4 storage appliance that refuses to chown files
to 36:36 because those users are not known to the appliance.
