Ganeti is a cluster virtual server management software tool built on top of existing virtualization technologies such as Xen or KVM and other Open Source software.

Ganeti requires pre-installed virtualization software on your servers in order to function. Once installed, the tool will take over the management part of the virtual instances (Xen DomU), e.g. disk creation management, operating system installation for these instances (in co-operation with OS-specific install scripts), and startup, shutdown, failover between physical systems. It has been designed to facilitate cluster management of virtual servers and to provide fast and simple recovery after physical failures using commodity hardware.

This guide explains how you can install and use KVM for creating and running virtual machines on a Debian Lenny server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.

In this post we will see how can we prepare a bootable USB Debian Lenny installation media to install Debian Linux on any storage device (IDE/USB hard drives). Note that this post is a bit different than the rest of the post

Installing Debian Lenny from a USB memory stick (USB HDD)

In this tutorial we'll see how to process N-Triples data by pipelining standard Unix tools such as grep, wc, cut, awk, sort, uniq, head and tail.
