The Definitive Guide to the Xen Hypervisor

The Xen hypervisor has become an incredibly strategic resource for the
industry, as the focal point of innovation in cross-platform
virtualization technology. David's book will play a key role in helping
the Xen community and ecosystem to grow.?

An Under-the-Hood Guide to the Power of Xen Hypervisor Internals

The Definitive Guide to the Xen Hypervisor is a comprehensive handbook
on the inner workings of XenSource's powerful open source
paravirtualization solution. From architecture to kernel internals,
author David Chisnall exposes key code components and shows you how the
technology works, providing the essential information you need to fully
harness and exploit the Xen hypervisor to develop cost-effective,
highperformance Linux and Windows virtual environments.

Granted exclusive access to the XenSource team, Chisnall lays down a
solid framework with overviews of virtualization and the design
philosophy behind the Xen hypervisor. Next, Chisnall takes you on an
in-depth exploration of the hypervisor's architecture, interfaces,
device support, management tools, and internals�including key
information for developers who want to optimize applications for virtual
environments. He reveals the power and pitfalls of Xen in real-world
examples and includes hands-on exercises, so you gain valuable
experience as you learn.

This insightful resource gives you a detailed picture of how all the
pieces of the Xen hypervisor fit and work together, setting you on the
path to building and implementing a streamlined, cost-efficient virtual
enterprise.
