Xen is a GPLed virtualization solution available in Debian 4.0 Etch repositories. This article help you to create a coherent Xen installation, with backups and minimum security enhancements. This guide fits my vision of a Xen setup. If it does not fit yours, you are free to adapt it to your needs, or to not use it. For information In this guide, i use the term "virtual host". Be aware that Xen use its own terminology. In a Xen setup, instanciated (aka. started) virtual hosts are called "Domains". Once your computer configured for Xen, all the operating systems run in "domains". The original operating system, where the Xen's control tools are installed, is called "dom0" (for domain No zero). All the guest operating systems are said to be installed in a "domU" (for User domain). As i'm a little lazy (well, yeah... very lazy), i don't want to endure this mind twisting, and i will mainly use the "virtual host" term in this guide. So, if you read this guide, don't by angry at me because of the terms i use.
