I’ve updated the OpenStackInstaller script which now gives you a Development (Trunk) OpenStack Essex installation on Ubuntu Precise (Currently Alpha 2) with the following
Nova Compute (and associated services)
This set up allows you to use nova client tools to launch instances
Install Ubuntu Precise
git clone https://github.com/uksysadmin/OpenStackInstaller.git
git checkout essex
A lot of this wouldn’t be possible without the help of people in #openstack on freenode.org.
For an equally awesome installation from scripts for a Diablo release view these scripts: https://github.com/managedit/openstack-setup
