** Guide Updated **
This guide is an evolution from this original guide. Unless the Kerrighed Team comes up with a substantially different version, this is the only update to this guide I will ever make as the steps are pretty much the same for all svn versions I have tested.

There are many guides found on the net describing Kerrighed and how to set it up using Ubuntu and others. However, to the best of my knowledge there isn't a step by step guide specifically designed for Kerrighed using Debian Lenny. So here it is. You can set up your own Beowulf Cluster using Debian Lenny and Kerrighed in about 50 steps. Many of the steps described here are taken straight from other guides because there are applicable here (see sources at the bottom.) Many other steps are based on my own trial and error.

Scenario: You have one host [ hoster ] running KVM on UBUNTU with 1 network interface accessing to internet.
You want to have 2 debian etch virtual servers [ guest ] ( debian01 and debian02 ) running on your hoster with network access between them and hoster in a local LAN. In this case virtual servers will not be able to access to internet, but later I will explain how to do it.
Problem: connect to the Internet via mobile phone and GPRS using USB-adapter Prolific PL2303 under Linux.
Solution: there are enough tools in Debian to do so.
The basics for any network based on *nix hosts is the Transport Control Protocol/ Internet Protocol (TCP/IP) combination of three protocols. This combination consists of the Internet Protocol (IP),Transport Control Protocol (TCP), and Universal Datagram Protocol (UDP).
You can configure a network interface from the command line using the basic Linux networking utilities. You configure your network client hosts with the command line by using commands to change your current settings or by editing a number of system files. Two commands, ifconfig and route, are used for network configuration. The netstat command displays information about the network connections.
