Xen is very actively developed upstream at xen.org,
and also the bits needed to support Xen dom0 in Linux 
were recently merged to upstream kernel.org Linux kernel!


The problem with RHEL6/CentOS6 is that Redhat bought
Qumranet (the KVM company) and decided to only ship
KVM host support in RHEL6. 

RHEL6/CentOS6 runs as Xen VM though, so you can use
RHEL5/CentOS5 Xen host (dom0) and run EL6 VMs on it.
