Hi Tibor, Can you please explain this part: " After this I just wondered, I will ma= ke a new VM with same disk and I will copy the images (really just rename) fro= m original to recreated." What were the exact steps you took?
Thanks

Hi,
Thank you for your reply.
So. I have a disk with snapshot. Or - really - I just think that is a sn= apshot. It was attached originally to a VM (with other two disks, that is not ha= ve snapshot) I did a detach-attach-storage procedure, but after attach, - I= don't know why - ovirt could not import the VM and disks from this (ovirt said= it is not possible). After this I just wondered, I will make a new VM with sam= e disk and I will copy the images (really just rename) from original to recreat= ed.
It was partial success because the VM can boot, but the disk, where ther= e is a snapshot I can't read the LVM table. I see just it seems to corrupt. Now this disk in a very interested state: I can see the snapshot datas f= rom the vm as raw disk. I think Ovirt don't know that is a snapshotted image and attach to VM as= raw disk.
So my really question, how can I add this disk image as good to ovirt?
Please help me, it is very important me.:(
Thanks in advance,
Have a nice day,
Tibor

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 t= he 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 the= m. I found this while I've try to migrate a storage-domain between two da= tacenter. Because, I didn't import that vm from the storage domain, I did an ano= ther similar VM with exactly same sized thin-provisioned disks. I have rena= med, 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, forma= t 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 snapsho= ts with qemu-img info and qemu-img snapshot -l , but it does not see any snaps= hots 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 im= age, 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,
