Today, nearly every modern computing-related company uses directly or indirectly a virtualization software. As seen with the recent Cloud computing trend, it is a sector that recently exploded in popularity and it is now accessible to everyone.
There are now a LOT of alternatives to virtualize an OS :
Isolation : OpenVZ, VServer, LXC, UML, BSD jails, Solaris zones…
Paravirtualization : Xen
Full virtualization : VMWare Player/Workstation/ESX/ESXi, KVM/Qemu, Virtualbox, Bochs…
When having to deal with a large pack of machines for building packages, testing software on multiple OSes or optimally use a powerful server with lots of RAM, you rapidly should, if not have to, realize that Virtual Machines can make your life significantly easier. It was the case for us.

This is a collection of notes I took while setting up a virtual machine host which has several guest virtual machines running on Ubuntu 8.10.

Manage your virtual machines
From the shell
You can manage your VMs from the shell using virsh. You can get a list of the available commands if you type "help". Type "help command" to get additional infos for a particular command.

Welcome to the VirtualBox® Images project website. This project provides virtual machines for Sun XVM VirtualBox® sporting several free and/or open-source operating systems, such as GNU/Linux or Free/Net/OpenBSD for testing, security and/or entertainment purposes.

In most cases, we’ve done a minimal setup, to let you alter the images to your own needs and learn how to use the operating systems. We will try to provide instructions for key tasks (for example, installing Guest Additions) for each image.
