If you feel to lazy to type the install guide in, there is an scripted version of it. It is called BOMSI, and it can build you a full multinode test environment on a single click.

Currently it works using CentOS as a base system (Kilo and Liberty), but an Ubuntu version should be coming out in a few days, with substantial improvements on structure of the source code.

This is the git repository of the BOMSI project: https://github.com/julenl/BOMSI/

I was able to install DevStack stable/liberty release on an all-in-one Ubuntu Trusty VM following http://docs.openstack.org/developer/devstack/. I found the master branch on GitHub needed debugging during the install. But stable/liberty branch installed smoothly so git clone stable/liberty branch. If your Ubuntu is behind proxy, then set environment variables http_proxy, https_proxy, no-proxy. If your proxy uses self-signed certificates, then it'd be hard (hopefully some folks know how to install in this situation).
