I might be missing something, but that link seems to talk about FAI and doesn't mention xen. I'm interested in seeing how it can install on the LVM partition but the OS doesn't see it as an entire disk with a partition table. What does "fdisk -l" show, then?

Here is a good link: http://wiki.rpath.com/wiki/Xen_DomU_Guide

Based on that link, this seems like a regular install of Xen onto a LVM partition. I thought Amos was referring to some special setup.

CentOS can definitely do this. Just setup LVM, and then manually edit the /etc/xen/myvm file so that the disk line is:

disk = [ 'phy:/dev/myvg/mylv,xvda,w', ]
