Professional Xen Virtualization Xen is an open source virtualization technology that allows multiple operating systems to run on a single physical computer system, providing cost savings and increased efficiency. This book presents you with a complete foundation on this exciting technology and shows you how Xen virtualization offers faster response times for new server and service requests, a simplified system administration for multiple systems, and better availability for critical computing resources.
You'll begin by examining the basic concepts of Xen as you also explore how to successfully make the most of today's virtualization technologies. You'll discover how virtualization with Xen allows for simpler and less expensive disaster recovery planning and affords increased productivity in system and software testing groups. Packed with detailed examples of Xen configuration files, system configuration files, and system-level configuration information, this book will show you why Xen virtualization is among the leading emerging technologies on the Linux platform and is being integrated into virtually every commercial distribution.
What you will learn from this book How Xen offers significant savings in infrastructure costs, such as power and cooling Ways to better document system configuration and characteristics How to build Xen from source code and the software requirements for building Xen Techniques for building virtual machine filesystems How to troubleshoot Xen configuration files and virtual machines
