Comments on The Perfect Xen Setup For Debian And Ubuntu

The Perfect Xen Setup For Debian And Ubuntu This tutorial provides step-by-step instructions on how to install Xen (version 2) on a Debian Sarge (3.1) system. It should apply to Ubuntu systems with little or no modifications.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. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one.

This has been a very helpful howto. Thanks for creating it. A follow up for xen 3 would be appreciated!

Hi,

can you change this (on first page):

 

echo server1.example.com > /etc/hostname

 

to this:

 

echo server1 > /etc/hostname

 

Quote from `man hostname':

FILES
       /etc/hosts /etc/hostname This file should only contain domain name and not the full FQDN.

Thank you.

How old is this document ?

The biggest problem I have found with open source software is the abundance of undated out-of-date instruction with unstated assomptions or prerequisites. The learning curve is steep enough without deliberately making it harder.
