You may want to use libvirt 0.9.0 if it is supported by OpenNebula.

The key feature added is:

* Add libxenlight driver (Jim Fehlig and Markus Groß)

http://article.gmane.org/gmane.comp.emulators.libvirt.user/1229/match=libxenlight

I'm not familiar enough with the errors that OpenNebula is showing
above, but libvirt support for libxenlight/libxl is the way forward
(xend is deprecated as of 4.1)

Some further Xen information that may be helpful
http://wiki.xensource.com/xenwiki/Xen4.1
http://wiki.xensource.com/xenwiki/MigrationGuideToXen4.1%2B
http://wiki.xensource.com/xenwiki/HostConfiguration/Networking

Let Xen.org know if we can be helpful in troubleshooting the
Xen/libvirt side of things.

Thanks,
Todd
