The first cut of the Ansible deployment playbook for deploying Eucalyptus private clouds is ready. I've merged the first "release" into the master branch here: https://github.com/lwade/eucalyptus-playbook. Feedback and contributions are very welcome, please file issues against the project.
This playbook allows a user to deploy a single front-end cloud (i.e. all component on a single system) and as many NC's as they want.
