I think the article kind of misses a bit about qemu-kvm + libvirt and the tools. You can administer a guest and view it's display output via qemu+ssh protocol and ssh keys for a very easy way to run vms on multiple hosts via an easy graphical interface ( and the command line. With the graphical tool it is also very easy to setup and run local virtual machines like VirtualBox.
