Complete Coverage of Xen, Including Version 3.2Virtualization 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 ModelFind a complete overview of the architecture model as well of all products: Xen 3.0 , Xen Express, XenServer, and Xen Enterprise.* Deploy XenUnderstand the system requirements, learn installation methods, and see how to install Xen on a free Linux distribution.* Master the Administrator ConsoleLearn 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 ToolsUse products like openQRM, Enomalism, and Project ConVirt to manage the VMM.* Deploy a Virtual Machine in XenLearn about workload planning and installing modified guests, unmodified guests, and Windows guests.* Explore Advanced Xen ConceptsBuild a Xen Cluster, complete a XenVM migration, and discover XenVM backup and recovery solutions.* See the Future of VirtualizationSee the unofficial Xen road map and what virtual infrastructure holds for tomorrow's data center.* See Other Virtualization Technologies and How They Compare with XenTake 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
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).
Packed with practical advice, this hands-on guide provides valuable information you need to most effectively optimize and manage the XenServer open source virtualization platform. Whether you run a modest installation of a few blades or multiple global enterprise datacenters, this book focuses on the most critical issues you’re likely to encounter when designing a XenServer deployment and helps you handle day-to-day management tasks. Tim Mackey and J.K. Benedict from Citrix Systems, the company that manages XenServer, show you how to design a deployment through best practices, deployment blueprints, and installation guidelines. The book’s second part features concise, easy-to-implement recipes for day-to-day management, such as user rights, backup strategies, and hardware maintenance. Learn precisely what makes a XenServer work, and how it can host 1000 virtual machines Explore the core components of a production XenServer environment Investigate several options on how and where to install XenServer Examine several factors for "right sizing" your XenServer deployment to fit your needs Work with a decision tree to optimize your XenServer deployment design Understand how to accommodate guest VM virtualization modes Use recipes that help you plan for, obtain, and apply XenServer upgrades
Virtual Machine technology applies the concept of virtualization to an entire machine, circumventing real machine compatibility constraints and hardware resource constraints to enable a higher degree of software portability and flexibility. Virtual machines are rapidly becoming an essential element in computer system design. They provide system security, flexibility, cross-platform compatibility, reliability, and resource efficiency. Designed to solve problems in combining and using major computer system components, virtual machine technologies play a key role in many disciplines, including operating systems, programming languages, and computer architecture. For example, at the process level, virtualizing technologies support dynamic program translation and platform-independent network computing. At the system level, they support multiple operating system environments on the same hardware platform and in servers.Historically, individual virtual machine techniques have been developed within the specific disciplines that employ them (in some cases they aren't even referred to as "virtual machines), making it difficult to see their common underlying relationships in a cohesive way. In this text, Smith and Nair take a new approach by examining virtual machines as a unified discipline. Pulling together cross-cutting technologies allows virtual machine implementations to be studied and engineered in a well-structured manner. Topics include instruction set emulation, dynamic program translation and optimization, high level virtual machines (including Java and CLI), and system virtual machines for both single-user systems and servers.*Examines virtual machine technologies across the disciplines that use them—operating systems, programming languages and computer architecture—defining a new and unified discipline.*Reviewed by principle researchers at Microsoft, HP, and by other industry research groups.*Written by two authors who combine several decades of expertise in computer system research and development, both in academia and industry.
This book presents you with a complete foundation on the Xen 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. Packed with detailed examples of Xen configuration files, system configuration files, and system-level configuration information, this book shows you why Xen virtualization is among the leading emerging technologies on the Linux platform and is being integrated into virtually every commercial distribution.
