Well, I will backup all VMs to export domain, than create snapshot of ovirt and I will try to restart that server if its going to delete VMs from DB. Than I will report back. I think, that remote session will not be possible, but I can be wrong (I hope). _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users
