Further testing allowed me to get a one machine to work after a bare install with simply a #yum install xen so I am obviously now wrong in my assessment. At this point I believe it to be a simple problem in the CentOS/RH package of Xen (Or Xen itself) as I did try a Fedora Core 8 install and the same behavior was now noted: Some machines function before and after, and some don't function after! My Linux experience is far too new to allow me to troubleshoot through it, but considering the magnitude of machines I have tried I am shocked if this behavior is not exhibited with other people.
