This concise handbook targeted at Linux administrators and virtualization enthusiasts is ideal for professionals wanting an easy-to-navigate reference when working with Xen and virtualization. It offers bite-sized practical walkthroughs and experiential solutions for many common virtualization tasks using Xen. Using Fedora Core as host operating system, it shows how to add Xen support and create guest domains running different operating systems, then dissects a range of common virtualization tasks. Originally developed in 2003 at the University of Cambridge Computer Laboratory, Xen is an open-source paravirtualization technology allowing multiple operating systems to run on one physical hardware resource with near native performance. Xen supports several operating systems-Linux, FreeBSD, Windows, and NetBSD. There are now commercial versions of Xen that build on of the open-source version with additional enterprise features; this book explores and uses the open-source version of Xen.
