Hi<div><br></div><div>It seems that a libvirt problem, either is not running at pcls or it is misconfigured. You have a couple of hints about configuring libvirt for KVM at [1].</div><div><br></div><div>My other concern is your permissions problem. Are you using the OpenSUSE package or installing from source?</div>

<br>I did check the documentation at [1], the only thing missing is that I didn't perform the following line:<br><ul><li><div>
<code>/etc/default/libvirt-bin</code> : add <strong>-l</strong> option to <code>libvirtd_opts<br><span style="font-family:arial"></span></code></div></li></ul>, since I didn't have the mentioned file on my machine (I'm running OpenNebula 3.2.0 on an openSUSE 12.1 machine).<br>
<br>I was curious, and I run 'virsh -c qemu' command, resulting in the following:<br><br># virsh -c qemu<br>WARNING: no socket to connect to<br>error: internal error unexpected Xen URI path 'qemu', try ///var/lib/xen/xend-socket<br>

as I mentioned at the bottom of my previous email, I already run /var/tmp/one/im/run_probes with the necessary parameters on pcls (my only host), which resulted in the same (empty) output. The file exists, it just doesn't produce the expected (or any) output, and I couldn't find the reason so far.<br>
<br>I didn't try 'onehost sync', but I could try tomorrow morning (since I got home already, and I'm not at the respective computers), if you consider that it might help.<br><br>Any other suggestions?<br>
