[ovirt-users] Replacing Export Domain by Data Domain

Hello all, because using an export domain is deprecated i deleted my export domain and use now a data domain instead. I used the export domain for complete image backups of my production virtual machines. By using now a data domain its even more comfortable because i can clone a snapshot directly on my backup data domain. But there is a (small?) inconvenience: I cannot "unregister" the cloned snapshot and i dont want to see them all the time in the "Virtual Machines" list. For the moment i use a bookmark in the "Vms:" filter. After detaching the domain the VMs are away, reattaching brings them back for possible "Import VM". Is there a possibility to set the cloned VM directly to this "unregistered" state without detaching and reattaching the complete domain? Best regards, Robert
