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.
