The Definitive Guide to the Xen Hypervisor

[b]The Definitive Guide to the Xen Hypervisor [/b]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.
