I think the init scripts in Fedora rpm do more than the default scripts in 
upstream Xen.

So:
        - Do you have /proc/xen (xenfs) mounted? Do you have files in it? 
        - Do you have xen-evtchn driver loaded? Run lsmod if it's compiled as a 
module in your dom0 kernel.
 
Both of those need to be OK before xend starts.
