Usingfree, open source Xen virtualization software, you can save money, gainnew flexibility, improve utilization, and simplify everything fromdisaster recovery to software testing. Running Xen brings together allthe knowledge you need to create and manage high–performance Xenvirtual machines in any environment. Drawing on the unparalleledexperience of a world–class Xen team, it covers everything frominstallation to administration—sharing field-tested insights, bestpractices, and case studies you can find nowhere else.

Theauthors begin with a primer on virtualization: its concepts, uses, and advantages. Next, they tour Xen’s capabilities, explore the Xen LiveCD,introduce the Xen hypervisor, and walk you through configuring your ownhard–disk–based Xen installation. After you’re running, they guide youthrough each leading method for creating “guests” and migratingexisting systems to run as Xen guests. Then they offer comprehensivecoverage of managing and securing Xen guests, devices, networks, anddistributed resources. Whether you’re an administrator, data centermanager, developer, system integrator, or ISP, Running Xen will helpyou achieve your goals with Xen–reliably, efficiently, with outstandingperformance, and at a surprisingly low cost.
