Minimal DevStack VirtualBox setup

This is a very concise quickstart guide to setup an OpenStack DevStack limited to Keystone in a VirtualBox VM using Ubuntu Server LTS as the guest operating system. By limiting the DevStack to primarily deploy Keystone only, installation is quick and the machine does not take up much resources.

As the time of writing it uses up about 11 GB of disk space and 1 GB of RAM running Keystone.

This is meant for testing authentication and IDM-related things with OpenStack Keystone while disregarding other components. It can easily be extended by further components by adjusting the local.conf accordingly.
