OpenStack Beginner’s Guide V2.0 for Diablo on Ubuntu 11.10 Oneiric is now available as a pdf file. Please have a look it and let us know if you have any comments/suggestions/feedback. We will do our best to enhance the guide based on your suggestions.
We would like to thank Anne Gentle and all participants of DocBlitz sessions and several others who have given feedback on these pages, on the documentation pages of OpenStack and offline through emails.
What’s new in V2.0:
- Procedure for using PostgreSQL for Nova added
- Swift added to Installation & Configuration chapter and Storage Management chapter
- Revised the commands line options to be in sync with Diablo
- Dropped Dashboard section, for now, as the new version of Dashboard relies on Key Stone. We will include them back once the key issues releated to Keystone/Dashboard on Ubuntu get resolved.
- Dropped Role Based Access Control Chapter. This is undergoing rewrite and we will add it soon.
- Some language errors fixed
- Some errors in the architecture diagrams fixed

Nova-volume provides persistent block storage compatible with Amazon’s Elastic Block Store. The storage on the instances is non persistent in nature and hence any data that you generate and store on the file system on the first disk of the instance gets lost when the instance is terminated. You will need to use persistent volumes provided by nova-volume if you want any data generated during the life of the instance to persist after the instance is terminated.
Commands from euca2ools package can be used to manage these volumes.
Here are a few examples:
Nova Manage commands
OpenStack provides commands for administrative tasks such as user/role management, network management etc. In all the examples we will use username as “novadmin” and project name as “proj”. All the nova-manage commands will need to be run as “root”. Either run them as root or run them under sudo.
