Xen Virtualisation is a new book from Packt that helps Linux administrators use Xen virtualization for development, testing, virtual hosting or operating systems training. Written by Prabhakar Chaganti this book is a practical guide for supporting multiple operating systems with the Xen hypervisor.
Xen was originally developed in 2003 at the University of Cambridge Computer Laboratory and users now have the choices of both commercial and free versions of the Xen hypervisor. The commercial versions are built on top of the open-source version with additional enterprise features. In this book Chaganti explores and uses the open-source version of Xen.
Xen is an open-source paravirtualization technology that provides a platform for running multiple operating systems on one physical hardware resource, while providing close to native performance. Xen supports several operating systems like Linux, FreeBSD, Windows, and NetBSD. It enables the user to easily test, deploy and run their software and services on multiple operating systems with resource isolation and great performance. It is also a terrific way to consolidate servers, save hardware and maintenance costs, and minimize downtime.
