Hi Tibor, I am not sure I completely understand the scenario.
You have a VM with two disks and then you create a snapshot including the= two disks? Before creating the snapshot, did the VM recognize the two disks?

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 data= center. Because, I didn't import that vm from the storage domain, I did an anoth= er similar VM with exactly same sized thin-provisioned disks. I have rename= d, copied to here my originals.
The VM started successfully, but the disk that contain a snapshot did no= t 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 snapsho= ts in the image.
Really, I don't know how is possible this.

(nothing)
Because it is a very big (13 TB) disk I can't migrate to an another imag= e, because I don't have enough free space. So I just would like to use it i= n ovirt like in the past.
I have a very old ovirt (3.5)
How can I use this disk?
Thanks in advance,
