Please check /boot/grub/grub.conf
Xen hypervisor is a baremetal hypervisor, meaning you have to _boot_ into it
(xen.gz).
Xen hypervisor will then launch dom0 ("domain 0") Linux, which is used to
manage the system.
dom0 Linux kernel needs to be special xen-aware kernel, called kernel-xen in
rhel/centos.
So yeah.. normal kernel-PAE doesn't run as Xen dom0.
kernel-xen is always PAE enabled on 32bit, 64bit doesn't require/use special
PAE kernels.
