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 first chapter of this title concerns virtualization techniques that allow sharing computational resources basically, slicing a real computational environment into virtual computational environments that are isolated from one another. The Xen and OpenFlow virtualization platforms are then presented in Chapter 2 and a performance analysis of both is provided. This chapter also defines the primitives that the network virtualization infrastructure must provide for allowing the piloting plane to manage virtual network elements. Following this, interfaces for system management of the two platforms are proposed in Chapter 3. To control and manage virtual network elements, five primitives that the network virtualization infrastructure must provide are defined: instantiate, delete, migrate, monitor and set. The book then moves on to survey existing control algorithms for virtual networking. It also describes the main challenges for packet forwarding using Xen as a virtualization tool and describes, in more detail, a proposal for local control of virtual networks. Within each physical node, this proposal guarantees the service level acquired by each virtual network, even in the presence of misbehaving virtual networks. Contents 1.

Book Description
“This accessible and immediately useful book expertly provides the Xen community with everything it needs to know to download, build, deploy and manage Xen implementations.” —Ian Pratt, Xen Project Leader VP Advanced Technology, Citrix Systems The Real–World, 100% Practical Guide to Xen Virtualization in Production Environments Using free, open source Xen virtualization software, you can save money, gain new flexibility, improve utilization, and simplify everything from disaster recovery to software testing. Running Xen brings together all the knowledge you need to create and manage high–performance Xen virtual machines in any environment. Drawing on the unparalleled experience of a world–class Xen team, it covers everything from installation to administration—sharing field-tested insights, best practices, and case studies you can find nowhere else. The authors begin with a primer on virtualization: its concepts, uses, and advantages. Next, they tour Xen’s capabilities, explore the Xen LiveCD, introduce the Xen hypervisor, and walk you through configuring your own hard–disk–based Xen installation. After you’re running, they guide you through each leading method for creating “guests” and migrating existing systems to run as Xen guests. Then they offer comprehensive coverage of managing and securing Xen guests, devices, networks, and distributed resources. Whether you’re an administrator, data center manager, developer, system integrator, or ISP, Running Xen will help you achieve your goals with Xen–reliably, efficiently, with outstanding performance, and at a surprisingly low cost. •Understanding the Xen hypervisor: what it does, and how it works •Using pre-built system images, including compressed file systems •Managing domains with the xm console •Populating and storing guest images •Planning, designing, and configuring networks in Xen •Utilizing Xen security: special purpose VMs, virtual network segments, remote access, firewalls, network monitors, sHype access control, Xen Security Modules (XSM), and more •Managing guest resources: memory, CPU, and I/O •Employing Xen in the enterprise: tools, products, and techniques
