I’ve been using DevStack for quite a while now. DevStack is a documented shell script from RackSpace Cloud Builders to build complete OpenStack development environments. Would recommend it for any developer trying to get OpenStack up and running with minimum fuss. The complete installation instructions are available at http://devstack.org

Keystone, the identity and authentication service of OpenStack often relies on MySQL as the back end Database server.

One of the most common errors I have encounted is the MySQL Access denied error. The URL to trouble shoot such kind of errors is http://dev.mysql.com/doc/refman/5.5/en/access-denied.html

I’ve just completed a creative commons licensed document on Ubuntu Image/Instance hardening at my workplace (peer review and testing pending prior to publishing). I was reading through the OpenStack mailing list and a post on the concept of OpenStack Trust Computing Pools struck me. Trust computing pools is a mechanism for verifying if nodes are running on good hypervisors and also in a running environment that is reliable.
