Hi,<div>I was facing a similar issue. It seems that Xen 4.1 doesnt understand sched-cred but it does understand<b> sched-credit</b>. To resolve the issue, I changed sched-cred to sched-credit in <b>xenrc</b> file located at /var/tmp/one/vmm/xen/xenrc on the cluster host where xen 4.1 is installed.</div>
<div><br></div><div>Below is the line to change:</div><div><div>export XM_CREDITS="sudo $XM_PATH sched-cred"</div></div><div>to</div><div><div><b>export XM_CREDITS="sudo $XM_PATH sched-credit"</b></div>
</div><div><br></div><div>Everything worked fine thereafter. Hope this helps.</div><div><br></div><div>Prakhar<br><br><div class="gmail_quote">On Wed, May 4, 2011 at 2:28 PM, Ruben S. Montero <span dir="ltr"><<a href="mailto:rubensm@dacya.ucm.es">rubensm@dacya.ucm.es</a>></span> wrote:<br>

</div></div>You may want to use libvirt 0.9.0 if it is supported by OpenNebula.<br>
<br>
The key feature added is:<br>
<br>
* Add libxenlight driver (Jim Fehlig and Markus Groß)<br>
<br>
<a href="http://article.gmane.org/gmane.comp.emulators.libvirt.user/1229/match=libxenlight" target="_blank">http://article.gmane.org/gmane.comp.emulators.libvirt.user/1229/match=libxenlight</a><br>
<br>
I'm not familiar enough with the errors that OpenNebula is showing<br>
above, but libvirt support for libxenlight/libxl is the way forward<br>
(xend is deprecated as of 4.1)<br>
<br>
Some further Xen information that may be helpful<br>

Let Xen.org know if we can be helpful in troubleshooting the<br>
Xen/libvirt side of things.<br>
<br>
Thanks,<br>
