云计算主机内核虚拟化技术框架及其性能分析

Research and Performance Analysis of Cloud Computing Host Kernel Virtualization Technology Framework

近些年来,云计算已经成为了互联网领域的一个重要基础设施,越来越多的应用被部署到云计算平台上提供在线或者离线的服务.而虚拟化技术则是云计算的关键技术,提供包括计算、存储和网络在内的资源,一直是云计算技术研究领域的热点问题.从内核虚拟化技术-KVM出现,成为了目前主机虚拟化的主流技术之一.本文对KVM虚拟化技术的架构进行了详细地研究和分析.详细介绍了KVM架构以及环境的构建过程,对于KVM架构中包含的模块以及工作流程进行了详细深入的分析,并对KVM的性能进行测试,得到了有效的对比信息,可作为相关研究和工程技术的参考,具有较高的技术价值.

Cloud computing has become an important infrastructure of the Internet, and more and more applications are deployed into cloud computing to provide the online service. Virtualization technology is the key element of cloud computing and hot research field, and it provides the computation, storage and network resource virtualization. KVM whose kernel is virtualization has become the one of the main virtualization technologies. This paper analyzes the structure of KVM, and introduces the working process of KVM. Finally, we also test the performance of KVM and get the useful results. These results, which are useful for technology improvement, can be used to improve the virtualization technology.
