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.

qemu-img snapshot -l 5974fd33-af4c-4e3b-aadb-bece6054eb6b
(nothing)
Because it is a very big (13 TB) disk I can't migrate to an another image, because I
don't have enough free space. 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
