Hi <br><br>Thanks for the info Florian. I have rechecked the source code and found <b>dev</b> instead of <b>file</b>. I might have mistyped it somehow. I have changed it to <b>file</b> and everything is working fine now.<br>
<br>Thanks for creating the bug Ruben :)<br><br> <br><div class="gmail_quote">On 28 May 2010 15:06, Ruben S. Montero <span dir="ltr"><<a href="mailto:rubensm@dacya.ucm.es">rubensm@dacya.ucm.es</a>></span> wrote:<br>

<br>
I think that the patch proposed by Shashank should fix the problem,<br>
and as Florian said it is quite strange that Libvirt.cc uses "<source<br>
file=" and the logs you are showing is "<source dev="<br>
<br>
I fill a ticket for this <a href="http://dev.opennebula.org/issues/245" target="_blank">http://dev.opennebula.org/issues/245</a><br>
<br>
Thank you very much for your feedback and patches !<br>
<br>
