No it doesn't work, the reason is always the same, some disks
reference on the lun were broken...<br>

all,<br>
<br>
I'm about to lose one very important vm. I
shut down this vm for maintenance and then
I moved the four disks to a new created
lun. This vm has 2 snapshots.<br>
<br>
After successful move, the vm refuses to
start with this message:<br>
<br>

u'domainID':

<br>
I tried to merge the snaphots, export ,
clone from snapshot, copy disks, or
deactivate disks and every action fails
when it is about disk.<br>
<br>
I began to dd lv group to get a new vm
intended to a standalone libvirt/kvm, the
vm quite boots up but it is an outdated
version before the first snapshot. There
is a lot of disks when doing a "lvs | grep
961ea94a" supposed to be disks snapshots.
Which of them must I choose to get the
last vm before shutting down? I'm not used
to deal snapshot with virsh/libvirt, so
some help will be much appreciated.<br>

<div>The disks which you want to copy should
contain the entire volume chain.</div>
<div>Based on the log you mentioned, It looks
like this image is problematic:</div>
<div><br>
</div>
<div> storage id:
'961ea94a-aced-4dd0-a9f0-266ce<wbr>1810177',</div>
<div> imageID': u'4a95614e-bf1d-407c-aa72-2df4<wbr>14abcb7a<br>
</div>
<div> volumeID': u'a0b6d5cb-db1e-4c25-aaaf-1bbe<wbr>e142c60b'</div>
<div><br>
</div>
<div>What if you try to deactivate this image
and try to run the VM, will it run?</div>
</div>
</div>
</div>
</blockquote>
</span> I already tried to do what you suggest, but it is
the same, and more this disk is part of a volume groupe,
so I can't boot the vm without it.<span class=""><br>

Beside specific oVirt answers, did you try to
get informations about the snapshot tree with
qemu-img info --backing-chain on the adequate
/dev/... logical volume?<br>
As you know how to dd from LVs, you could
extract every needed snapshots files and
rebuild your VM outside of oVirt.<br>
Then take time to re-import it later and
safely.<span
