虚拟机宿主服务器及其性能收集方法研究

介绍了虚拟化技术的概念和研究范围,接着探讨计算平台虚拟化及高可用等特性,引入虚拟机宿主服务器的概念,指出为了发挥虚拟化技术的特性,对虚拟机宿主服务器进行性能数据收集的必要性,以EsxServer和Xen为性能收集对象,分别探讨性能收集方法.具体方法是针对不同虚拟化产品,相应使用了Linux命令查询解析、虚拟化监视器命令解析及数据管理对象访问.最后以虚拟化产品厂商提供的性能监视数据作为参照,指出了性能收集方法的优劣.

Research of VM-hosted servers and performance collecting methods

The virtualization technology is introduced including its conception and research range. The computing platform virtualization is discussed later, involving the term VM-hosted servers. Then the necessity is pointed out which emphasized to collect performance information from VM-hosted servers to take advantage of features of virtualization. After that the information gathering methods for Esx Server and Xen are discussed, such as query and analysis by Linux command, analysis by VMM command and data management objects access. According to the data from tools of virtualization products manufactures, the Pros and Cons of these implied methods are analyzed.
