This will be a full tutorial on installing OpenStack (minimal config). I would very much like to try open-source cloud OS, and OpenStack is one of the serious solutions, used by many institutions and businesses. Cern is one among the users, and Red Hat is strong supporter of OpenStack. 

Be aware: Even after this “ironed out” tutorial, you will be greeted with errors after you set everything up, and you will need to research more to get your OpenStack to work ok. I will write about some of the problems in a few more quick guides.
