Download or read book Interaction of Virtual Machine with the Operating System written by Kiran Tati and published by . This book was released on 2002 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: As applications executing in virtual machine runtime environments such as the Java Virtual Machine and the .NET Common Language Runtime become more prevalent on desktop operating systems, this trend raises the interesting question of the best model for supporting multiple applications in virtual machine environments. A natural model is to execute each application in its own virtual machine process. However, multiple applications could also be executed in a single virtual machine process by leveraging the protection and security features of the programming languages used by the applications. Executing within a single virtual machine process makes it easier to share code and data and communicate among the processes. In this paper, we present an intermediate model for supporting multiple applications in virtual machine environments for desktop operating systems. We argue that applications should take advantage of the protection features and resource management provided by the operating system and execute each application in its own virtual machine process. However, to facilitate code reuse, reduce application initialization time, and facilitate interprocess communication among applications in different virtual machines, we propose extending virtual machine implementations with the use of a shared class cache and an efficient serialization implementation optimized for local machine interprocess communication. To demonstrate and evaluate our approach, we describe the design and implementation of a shared class cache and optimized class serialization in the Java virtual machine, and evaluate our implementation using a set of application and micro-benchmarks.
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 Hardware and Software Support for Virtualization written by Edouard Bugnion and published by Springer Nature. This book was released on 2022-06-01 with total page 188 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 Fundamentals of Operating Systems written by LISTER and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: An operating system is probably the most important part of the body of soft ware which goes with any modern computer system. I ts importance is reflected in the large amount of manpower usually invested in its construction, and in the mystique by which it is often surrounded. To the non-expert the design and construction of operating systems has often appeared an activity impenetrable to those who do not practise it. I hope this book will go some way toward dispelling the mystique, and encourage a greater general understanding of the principles on which operating systems are constructed. The material in the book is based on a course of lectures I have given for the past few years to undergraduate students of computer science. The book is therefore a suitable introduction to operating systems for students who have a basic grounding in computer science, or for people who have worked with computers for some time. Ideally the reader should have a knowledge of prorramming and be familiar with general machine architecture, common data structures such as lists and trees, and the functions of system software such as compilers, loaders, and editors. I t will also be helpful if he has had some experience of using a large operating system, seeing it, as it were, from the out side.

Implementing virtualization allows for more efficient utilization of network server capacity, simpler storage administration, reduced energy costs, and better use of corporate capital. In other words: virtualization helps you save money, energy, and space. Not bad, huh? If you’re thinking about “going virtual” but have the feeling everyone else in the world understands exactly what that means while you’re still virtually in the dark, take heart. Virtualization for Dummies gives you a thorough introduction to this hot topic and helps you evaluate if making the switch to a virtual environment is right for you. This fun and friendly guide starts with a detailed overview of exactly what virtualization is and exactly how it works, and then takes you on a tour of the benefits of a virtualized environment, such as added space in overcrowded data centers, lower operations costs through more efficient infrastructure administration, and reduced energy costs through server consolidation. Next, you’ll get step-by-step guidance on how to: Perform a server virtualization cost versus benefit analysis Weigh server virtualization options Choose hardware for your server virtualization project Create a virtualized software environment Migrate to—and manage—your new virtualized environment Whether you’re an IT manager looking to sell the idea to your boss, or just want to learn more about how to create, migrate to, and successfully manage a virtualized environment, Virtualization for Dummies is your go-to guide for virtually everything you need to know.
