a€œThe Xen hypervisor has become an incredibly strategic resource for the industry, as the focal point of innovation in cross-platform virtualization technology. Davida€™s book will play a key role in helping the Xen community and ecosystem to grow.a€ a€“Simon Crosby, CTO, XenSource 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 XenSourcea€™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 hypervisora€™s architecture, interfaces, device support, management tools, and internalsa€”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. Coverage includes Am Understanding the Xen virtual architecture Am Using shared info pages, grant tables, and the memory management subsystem Am Interpreting Xena€™s abstract device interfaces Am Configuring and managing device support, including event channels, monitoring with XenStore, supporting core devices, and adding new device types Am Navigating the inner workings of the Xen API and userspace tools Am Coordinating virtual machines with the Scheduler Interface and API, and adding a new scheduler Am Securing near-native speed on guest machines using HVM Am Planning for future needs, including porting, power management, new devices, and unusual architecturesGoing even smaller, virtualization provides the potential for much better security for devices such as mobile phones, a possibility being investigated actively by Samsung. ... Much of the code in the Linux power management subsystem is there to try to work around these bugs in specific ... The obvious solution is to cheat in the same way that Xen does for other hardware support: delegate it to Domain 0.
