Virtualization is something that is sneaking up on us: Debian based Xen setup

Virtualization is something that is sneaking up on us. It has moved from the novelty stage, to the practical. Ubiquitous only remains -- for when the consumer Processor manufacturers add completely hardware based support then will we know it has arrived.

The Perfect Xen 3.0 Setup For Debian | HowtoForge - Linux Howtos and Tutorials

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 (*nix operating systems like Linux and FreeBSD), 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.
