One option you might consider would be to install RHEL5 and then when CentOS 5 is released, "convert" (which is generally just a process of pointing your yum repo somewhere else and installing a couple CentOS RPM's, very easy to do on the fly). CentOS 4.4 of course will be supported for some years to come, but if the Xen stuff is important to you, it's probably worth waiting. Ray
