Hi,=20
Thank you for your reply.=20
So. I have a disk with snapshot. Or - really - I just think that is a snaps=
hot. It was attached originally to a VM (with other two disks, that is not =
have 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 (ovir=
t said it is not possible). After this I just wondered, I will make a new V=
M with same disk and I will copy the images (really just rename) from origi=
nal to recreated.=20
It was partial success because the VM can boot, but the disk, where there i=
s a snapshot I can't read the LVM table. I see just it seems to corrupt.=20
Now this disk in a very interested state: I can see the snapshot datas from=
the vm as raw disk.=20
I think Ovirt don't know that is a snapshotted image and attach to VM as ra=
w disk.=20
So my really question, how can I add this disk image as good to ovirt?=20
Please help me, it is very important me.:(=20
Thanks in advance,=20
Have a nice day,=20
Tibor=20

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?
