Hi Russ,

Thanks for your explanations. I agree that a personal rebuild of CentOS 
source may choose a Xen kernel instead of upstream kernel, and tools 
associated with this.

I must add that, due to the fact Dom0 has been included in recent Kernel 
3.0 tree, it will certainly be possible in future releases of RHEL, then 
CentOS, to choose either Xen or KVM as virtualization solution.
