Download or read book Hardware and Software Support for Virtualization written by Edouard Bugnion and published by Morgan & Claypool Publishers. This book was released on 2017-02-21 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the core question of the necessary architectural support provided by hardware to efficiently run virtual machines, and of the corresponding design of the hypervisors that run them. Virtualization is still possible when the instruction set architecture lacks such support, but the hypervisor remains more complex and must rely on additional techniques. Despite the focus on architectural support in current architectures, some historical perspective is necessary to appropriately frame the problem. The first half of the book provides the historical perspective of the theoretical framework developed four decades ago by Popek and Goldberg. It also describes earlier systems that enabled virtualization despite the lack of architectural support in hardware. As is often the case, theory defines a necessary—but not sufficient—set of features, and modern architectures are the result of the combination of the theoretical framework with insights derived from practical systems. The second half of the book describes state-of-the-art support for virtualization in both x86-64 and ARM processors. This book includes an in-depth description of the CPU, memory, and I/O virtualization of these two processor architectures, as well as case studies on the Linux/KVM, VMware, and Xen hypervisors. It concludes with a performance comparison of virtualization on current-generation x86- and ARM-based systems across multiple hypervisors.

Download or read book The Best Damn Server Virtualization Book Period written by Rogier Dittner and published by Syngress. This book was released on 2011-04-18 with total page 960 pages. Available in PDF, EPUB and Kindle. Book excerpt: Server Sprawl and escalating IT costs have managers and system administrators scrambling to find ways to cut costs and reduce Total Cost of Ownership of their physical infrastructure. Combining software applications onto a single server, even if those applications are from the same software vendor, can be dangerous and problems hard to troubleshoot. Virtualization allows you to consolidate many servers onto a single physical server reducing hardware, electrical, cooling, and administrative costs. These virtual servers run completely independent of each other so if one crashes the other are not affected. Planning and implementing a server consolidation is a complex process. This book details the requirements for such a project, includes sample forms and templates, and delivers several physical to virtual migration strategies which will save both time and costs. Readers of this book will easily be able to plan and deploy VMware, Microsoft Virtual Server, and Xen. - Create a virtual network to exchange information or provide a service to other virtual machines or computers - Use virtualization to support removable media such as CD or DVD optical disks - Reduce server costs, administration overhead, and complexity
Download or read book Virtual Machines written by Jim Smith and published by Elsevier. This book was released on 2005-07-12 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Service Virtualization written by John Michelsen and published by Apress. This book was released on 2013-02-01 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software drives innovation and success in today’s business world. Yet critical software projects consistently come in late, defective, and way over budget. So what’s the problem? Get ready for a shock, because the answer to the problem is to avoid reality altogether. A new IT practice and technology called Service Virtualization (SV) is industrializing the process of simulating everything in our software development and test environments. Service Virtualization is a method to emulate the behavior of components in heterogeneous applications such as "Service-Oriented Architectures" (SOA). Yes, fake systems are even better than the real thing for most of the design and development lifecycle, and SV is already making a huge impact at some of the world’s biggest companies. Service Virtualization: Reality Is Overrated is the first book to present this powerful new method for simulating the behavior, data, and responsiveness of specific components in complex applications. By faking out dependency constraints, SV delivers dramatic improvements in speed, cost, performance, and agility to the development of enterprise application software. Writing for executive and technical readers alike, SV inventor John Michelsen and Jason English capture lessons learned from the first five years of applying this game-changing practice in real customer environments. Other industries—from aviation to medicine—already understand the power of simulation to solve real-world constraints and deliver new products to market better, faster, and cheaper. Now it’s time to apply the same thinking to our software. For more information, see servicevirtualization.com.

Download or read book Concept for system virtualization in the field of high availability computing written by Stephan Winter and published by GRIN Verlag. This book was released on 2007-04-04 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2007 in the subject Computer Science - Software, University of Paderborn, language: English, abstract: Server virtualization is currently a field of IT which is undergoing a rapid development. Introducing an even spread of performance on server farms which results in a good TCO (total cost of ownership), virtualization has already got the full attention from industry, resulting in massive participation and huge acquisitions. With server virtualization the size of server farms can be reduced dramatically, resulting in a lower total cost of ownership and (by using techniques like Linux-HA in virtual environments) increased availability. Even with an overhead of 10-20% on the layer of virtualization it is still very interesting since the load on a server farm can be spread evenly (which is not only a main target in server virtualization but also in distributed systems in general). This work will give an insight on the current developments in the field of server virtualization and the various techniques involved in it as well as a short historical overview about when the first types of virtualization were introduced (and why they failed, since according to A. Tanenbaum the current hardware is not made to be virtualized). The findings will mostly be supported by examples of current virtual environments (especially the XEN project). The paper will first introduce the different ways of virtualizing a system and in how far hardware can or can not support this. The second part will introduce the current software for virtualizing a server and giving users their own separated environment, starting from early approaches like BSD jails to the Linux V-Server and XEN Project. The last chapter will cover the use of server virtualization in high-availability environments. With the use of n physical machines and m virtualized systems on each machine, an environment of (n * m) / x can be created, where x is the level of redundancy (e.g. x = 2 for mirroring). Most interesting is how virtual environments can be moved from one physical machine to another one without switching it off. The summary will give some insight on the current use of virtual environments and in how far they provide advantages over solutions like Mosix, Application-basic virtualization and the grid. It will also give an outlook on further developments especially in the field of hardware support for virtualization.
