I suppose this could be a news item but it is specialized to Virtual Computing so I thought I'd drop it here.

Xen is a paravirtualization technology available for the Linux kernel that lets you enclose and test new upgrades as if running them in the existing environment but without the worries of disturbing the original system. This article shows you how to install a Xen system that will give administrators a valuable sandbox for testing system upgrades (as well as a playground for running multiple virtual machines on the same Linux box). Take a look at virtualization on Linux and see the benefits that come from using Xen in that space.

With a steady flow of improvements and bug fixes to existing software, the open source world is in constant flux. Staying at the bleeding edge of software upgrades can be a full-time job. One of the trickiest parts about upgrading your software is that you never really know if your applications are going to work after the upgrade is complete. Most software packaging systems offer a rollback feature, but that's often not enough; ideally, you want to play with these new updates to test and try them in an environment where they can't hurt anything.

Like a kid on the playground, you want your own sandbox to play in, where you can make a mess and not worry about picking up.

Virtualization is often used to separate (or "sandbox") applications and systems from the others on the same hardware. Linux supports many different forms of virtualization ranging from hardware emulators to pure hardware virtualization. One recent standout in the growing list of virtualization technologies is Xen, developed at the University of Cambridge. Xen is noteworthy because of its unprecedented performance and security.
