Open Stack

Sort of an oddball thought, but Vagrant (vagrantup.com) could be used.
It'd replace all the screenshots with a file that would configure the
hypervisor correctly.  It does support multiple hypervisors[1], so it would
encapsulate all the different hypervisors and let a user get on with the
actual installation guide content.

I've used Vagrant for my DevStack vms for a long time, so I could help
whip something together.
