rhel xen

I've played with xen on Ubuntu and now I'm going to try it the RedHat way. So far I've installed my system with the virtualization option checked. This option seems to install tools like virt-manager and the xen kernel:

$ uname -a
Linux xen0.domain.tld 2.6.18-53.el5xen #1 SMP Wed Oct 10 
16:48:44 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux

I'm now reading the RedHat's Virtualization Guide.
