Before starting with the OpenNebula installation, there are some points to be noted.
The platform of choice for this book is Ubuntu Server v10.04 (the current long-term support) due to its growing community (http://ubuntuforums.org/) and availability of documentation (https://help.ubuntu.com/), guides, and how-tos on the Internet, (such as wikis or blogs).
In order for the book to be used as a working step-by-step guide, I will provide the exact commands needed, but I will try to stay as distribution-independent as possible, so that you can use them as reference for every GNU/Linux distribution supported by OpenNebula.
You need to install sudo to allow normal administration tasks from your normal user account. Many of the configuration steps require root
privileges, and with sudo, you do not need to switch between root
and normal user
accounts every now and then.
Monitoring the logfile is essential to detecting configuration problems. It would be nice to have a dedicated terminal...
