The Perfect Xen 3.1.0 Setup For Debian Etch (i386)
This tutorial provides step-by-step instructions on how to install Xen (version 3.1.0) on a Debian Etch (4.0) system (i386). 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.
