CentOS 5 predates KVM and used Xen for virtualization. CentOS 6 and 7 include
KVM for virtualization and don't use a Xen hypervisor. You are not 'missing'
anything: Xen is just the older virtualization hypervisor.

I don't want to take that step until I have learned to deal with the likes of
systemd, etc. I install CentOS 6 as the host and install CentOS 7 in a VM, to
have a standbox to learn in, and still be able to get work done.
