[CentOS] KVM in CentOS 5?

Hi folks,

I've been trying to do some KVM virtualization on a C5 host, and to my
surprise, there seems to be no kvm package in any of the repos.
Yum install kvm says:

No package kvm available.
Nothing to do

This machine is a CentOS release 5.10 (Final) with the
2.6.18-371.11.1.el5 kernel.

Also, the docs related to C5 on

  http://wiki.centos.org/HowTos/KVM

seem to be terribly outdated. What am I missing here?

TIA, :-)
Marko
