The Perfect Xen 3.0 Setup For Debian

This tutorial provides step-by-step instructions on how to install Xen (version 3.0.1) on a Debian Sarge (3.1) system.

Xen lets you create guest operating systems, so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware.
