Thats where I am stuck. I already deployed a working VM via Xen without 
OpenNebula (via XEN CLI) .
But now getting a template from the OpenNebula frontend/cli running is a 
different thing.

At least it was some encouragement to continue working on Xen 
integration. My backupplan is to drop Xen and switch to a KVM Cluster.

Ajub, that's why im trying Xen, KVM is only the backup plan

Working together sounds great, at least we would have a companion in 
misfortune.
Both ICQ and IRC are supported ;)
Don't have favorite irc server, so I suggest using the OpenNebula Channel.
