9:49 a.m.
On a 4.5.1 DC, I have imported a vm and its disk from an old 4.3 DC
(through an export domain if that's relevant)
The DC/Cluster compat level is 4.7 and the vm was upgraded to it.
"Original custom compatibility version 4.3 of imported VM xxx is not
supported. Changing it to the lowest supported version: 4.7."
The disk is raw and sparse :
<format>raw</format>
<sparse>true</sparse>
I initially put the VM's disks on an NFS storage domain, but I want to move
the disks to an iSCSI one
However, after copying data for a while the task fails "User has failed to
move disk VM-TEMPLATE-COS7_Disk1 to domain iSCSI-STO-FR-301"
in engine.log :

I do want the conversion from raw/sparse to qcow2/sparse to happen, as I
want to activate incremental backups.
I think that it may fail because the virtual size is bigger than the
initial size, as I think someone as explained on this list earlier? Can
anybody confirm?
It seems to be a pretty common use case to support though?

Did anyone have the chance to look at this problem?
It seems that it may be related to another problem we have encountered when
trying to import a vm with qcow2 disks that have been sparsified first
(virt-sparsify), from a kvm/libvirt provider to a iSCSI storage domain.
In those case, we get an error that the import failed, and in the import
log we can see a similar "qemu-img: error while writing at byte xxx: No
space left on device"
Obviously, it is not a storage space problem as in both situations we are
using an iSCSI LUN with ample free space.

Hello,
Just upping my message.
We have a frequent use of importing libvirt vms with sparsified qcow2
disks, so we have hit the import bug to iSCSI a lot of times already. Is it
an unsupported use case?
Same question about moving a raw/sparse disk from NFS volume to iSCSI.
Thanks for any feedback
