系统虚拟机实现技术综述

A survey of system virtual machine implementation techniques

本文简要介绍了虚拟化技术与虚拟机监视器(VMM)体系结构的分类,重点分析了系统虚拟机实现的核心技术-CPU虚拟化、内存虚拟化I、/O虚拟化以及硬件技术对虚拟化技术的支持,最后阐述了虚拟机应用现状以及虚拟化技术的发展前景。

This article briefly introduces the classification of both virtualization and VMM architecture. It mainly analyzes the virtualization implementation of CPU, memory and I/O, which are the main implementation technologies of virtual machines. Then it discusses how the hardware technology supports virtualization, and in the end it presents the current application of virtual machines and the trends of development of virtualization techniques.
