Yes - install it and modify grub.conf to use it, no need to reinstall. What the virtualization guide doesn't mention until the troubleshooting section is that you'll also want to modify DEFAULTKERNEL from "kernel" to "kernel-xen" in /etc/sysconfig/kernel, or future yum upgrades will switch your system back to using the non- Xen kernel by default. It also doesn't mention the full package list you'll need to use Xen. I found that "sudo yum -y install virt-manager kernel-xen" was enough to pull in everything. -- Scott Lamb <http://www.slamb.org/>
