Hi,
This is my datastore definition for my qcow2-based image store.

I recently had to restore my system from backup but forgot to include the .one/
directory in the backups.. thus I have no one_auth file at the moment for the

Without that, OpenNebula won't start and thus I can't do oneuser login which
is what I would
need to re-create it.
Good idea. In general it would be nice to be able to set the various

be controlled by the RHEV extended libvirt functions which include IOPS but
