Ok, did 'xl list' show a new value?  What does this command give you:

find /sys -name target_kb | xargs cat

Why?Did it crash? Was it running to slow? If you ran:
while (true)
do
 xl list | grep Domain-0
done

Did you see the numbers go up/down? Can you be more specific please?

Hm, as in.. you can't see Xen in it? If so, we need to rope in the
Xen libvirt expert from Novell. Can you send another email with details
and I will (once I recall his name) CC him.
