The xen0 kernel contains all the drivers required to run in a domU 
(unprivileged guest) *and* all the drivers required to run in dom0 (i.e. 
privileged command interface, device drivers for the real hardware, etc.).  
This'll run in *any* domain.

The xenU kernel contains only the drivers required to run in a domU - no 
privileged command interface, no drivers for real hardware.  The only 
practical difference is that this kernel is a few hundred kilobytes smaller 
but can only run in domUs.

HTH,
Mark
