Dear Users, I have a disk of a vm, that is have a snapshot. It is very interesting, because there are two other disk of that VM, but there are no snapshots of them. I found this while I've try to migrate a storage-domain between two datacenter. Because, I didn't import that vm from the storage domain, I did an another similar VM with exactly same sized thin-provisioned disks. I have renamed, copied to here my originals.
The VM started successfully, but the disk that contain a snapshot did not recognized by the os. I can see the whole disk as raw. (disk id, format in ovirt, filenames of images, etc) . I think ovirt don't know that is a snapshotted image and use as raw. Is it possible? I don't see any snapshot in snapshots. Also I have try to list snapshots with qemu-img info and qemu-img snapshot -l , but it does not see any snapshots in the image. Really, I don't know how is possible this.

So I just would like to use it in ovirt like in the past. I have a very old ovirt (3.5) How can I use this disk? Thanks in advance, Regards, Tibor
