Hi,<div>It appears that you are using the tm_ssh transfer drivers. Use tm_lvm transfer manager drivers instead.</div><div><br></div><div>Prakhar<br><br><div class="gmail_quote">On Thu, Dec 15, 2011 at 2:01 PM, Tengvall, Ilkka (NSN - FI Espoo) <span dir="ltr"><<a href="mailto:ilkka.tengvall@nsn.com">ilkka.tengvall@nsn.com</a>></span> wrote:<br>

Ruben, thanks for answer, you commented there that iscsi could be used<br>
as a disk:<br>
<br>
"you should be able to use iSCSI block devices with<br>
DISK=[TYPE=block,SOURCE=<path_to_dev>....]."<br>
<br>
I tried to follow you instruction, I don't see it working. What am I<br>
missing, since the oned tries to cp the iscsi image, instead as pass it<br>
to guest as disk:<br>
<br>

Creating the machine using the disk:<br>
<br>
--------------------------------<br>
$ onevm create iscsi-vm.txt<br>
ID: 10<br>
--------------------------------<br>
<br>
and after it fails I see from the logs that it tried to copy the image<br>
(cp), instead of passing it to libvirt as a virtio device:<br>
