Are they incompatible ? > 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. -- Pasi
