Book Description
Xen allows administrators to run many virtual operating systems on one physical server, including Linux, BSD, OpenSolaris, and Microsoft Windows. In the process, users save money on hardware, maintenance, and electricity. Not only is Xen open source, the Xen hypervisor (the virtual machine monitor) is the best-performing hypervisor available. "The Book of Xen" explains everything a sysadmin needs to know to use this powerful technology, with coverage of installation, networking, virtualized storage, and managing guest and host operating systems. Written for administrators who have worked with *NIX before but who may be new to virtualization, "The Book of Xen" covers both the basics and the trickier aspects of Xen administration, like profiling and benchmarks, migration, XenSource administration, and hardware assisted virtualization (HVM).

Book Description
"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." -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 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. Coverage includes Understanding the Xen virtual architecture Using shared info pages, grant tables, and the memory management subsystem Interpreting Xen's abstract device interfaces Configuring and managing device support, including event channels, monitoring with XenStore, supporting core devices, and adding new device types Navigating the inner workings of the Xen API and userspace tools Coordinating virtual machines with the Scheduler Interface and API, and adding a new scheduler Securing near-native speed on guest machines using HVM Planning for future needs, including porting, power management, new devices, and unusual architectures

Book Description
In a world devoid of rites of passage, Ezra Buckley finds himself confronted with the genuine prospect of having a life-changing, Liminal experience in the woods of Big Sur. What is it that he experiences? Is it the legendary Watchers of Big Sur phenomena or something else? Will he survive it? Is it even real? Xen is a work that confronts the questions of identity, modernity, life, the other, and the place for rites of passage in the modern world. “…wildly creative experiments with form…through a down-to-earth lens and with a sense of humor. … I felt spoken to many times as Ezra articulated his own frustrations with life and with his own expectations of the world.” – DAVID AMITO, award-winning Actor. Writer, Producer, Director of Antrum “This is tantalizing, intriguing, and weird stuff and we recommend it highly.” -Original Falcon Newsletter “What I appreciate about Buckley’s book is the sense of desperate and furious will-to-life/power, coupled with a playfulness that is wonderful.” – Julian Langer “I just finished reading this a few minutes ago. I guess “finished” isn’t really the correct wording… because I’ve really just begun.” Reader on Reddit

Book Description
Complete Coverage of Xen, Including Version 3.2 Virtualization with Xen is the first book to demonstrate to readers how to install, administer, and maintain a virtual infrastructure based on XenSource’s latest release, Xen 3.2. It discusses best practices for setting up a Xen environment correctly the first time, maximizing the utilization of server assets while taking advantage of the fastest and most secure enterprise-grade paravirtualization architecture. It covers both basic and advanced topics, such as planning and installation, physical-to-virtual migrations, virtual machine provisioning, resource management, and monitoring and troubleshooting guests and Xen hosts. * Explore Xen’s Virtualization Model Find a complete overview of the architecture model as well of all products: Xen 3.0 , Xen Express, XenServer, and Xen Enterprise. * Deploy Xen Understand the system requirements, learn installation methods, and see how to install Xen on a free Linux distribution. * Master the Administrator Console Learn how to use the command-line tools and the remote Java-based consoler that manages the configuration and operations of XenServer hosts and VMs. * Manage Xen with Third-Party Tools Use products like openQRM, Enomalism, and Project ConVirt to manage the VMM. * Deploy a Virtual Machine in Xen Learn about workload planning and installing modified guests, unmodified guests, and Windows guests. * Explore Advanced Xen Concepts Build a Xen Cluster, complete a XenVM migration, and discover XenVM backup and recovery solutions. * See the Future of Virtualization See the unofficial Xen road map and what virtual infrastructure holds for tomorrow’s data center. * See Other Virtualization Technologies and How They Compare with Xen Take a look at the different types of server virtualization, other virtual machine software available, and how they compare with Xen. Xen has the lead in the open-source community; now distributed as a standard kernel package for Novell’s SLES 10 and Red Hat’s RHEL 5 and Fedora Core 6 Linux distributions Covers installation, administration, management, monitoring, and deployment planning and strategies

Book Description
You know that servers have log files and performance measuring tools and that traditional network devices have LEDs that blink when a port does something. You may have tools that tell you how busy an interface is, but mostly a network device is a black box. Network Flow Analysis opens that black box, demonstrating how to use industry-standard software and your existing hardware to assess, analyze, and debug your network. Unlike packet sniffers that require you to reproduce network problems in order to analyze them, flow analysis lets you turn back time as you analyze your network. You'll learn how to use open source software to build a flow-based network awareness system and how to use network analysis and auditing to address problems and improve network reliability. You'll also learn how to use a flow analysis system; collect flow records; view, filter, and report flows; present flow records graphically; and use flow records to proactively improve your network. Network Flow Analysis will show you how to: –Identify network, server, router, and firewall problems before they become critical –Find defective and misconfigured software –Quickly find virus-spewing machines, even if they’re on a different continent –Determine whether your problem stems from the network or a server –Automatically graph the most useful data And much more. Stop asking your users to reproduce problems. Network Flow Analysis gives you the tools and real-world examples you need to effectively analyze your network flow data. Now you can determine what the network problem is long before your customers report it, and you can make that silly phone stop ringing.
