As of 19Aug2014 'DevStack is part of the QA program.
DevStack's mission is to provide and maintain tools used for the installation of the central OpenStack services from source (git repository master, or specific branches) suitable for development and operational testing. It also demonstrates and documents examples of configuring and running services as well as command line client usage.
DevStack is an opinionated script to quickly create an OpenStack development environment. It can also be used to demonstrate starting/running OpenStack services and provide examples of using them from a command line. The example exercises were fleshed out beyond simple examples and became useful as a quick sanity check for the OpenStack installation. That sanity check became the basis for the Gerrit gate tests for all OpenStack checkins and continues in that role until Tempest takes over. These remain as the driving priorities for ongoing DevStack development.
DevStack is not and has never been intended to be a general OpenStack installer. It has evolved to support a large number of configuration options and alternative platforms and support services. However, that evolution has grown well beyond what was originally intended and unfortunately many of the configuration combinations are rarely, if ever, tested.
See the DevStack Overview for more details on supported configurations.
The simplest way to try DevStack is to run script https://github.com/makelinux/devstack-install-on-iso, which automatically installs Ubuntu in VM and DevStack without any manual configuration.
