- How to change image features? - How to add upmap option to libvirt domain? - How libvirt domain looks like? - How snapshots works?
Snapshot works fine, going to VM tab and creating snapshot as usual.
- How clones works?
Disk copy can be done from the engine storage -> disk tab. VM cloning failed for me, opened *Bug 1982083* <https://bugzilla.redhat.com/show_bug.cgi?id=1982083> - Cloning VM with managed block storage raise a NPE
- How to migrate images from one domain to another?
I would let the storage team answer these questions in detail, +Benny Zlotnik <bzlotnik@redhat.com> ?
