Performance evaluation method aiming at KVM virtualization server

Abstract

The invention relates to a performance evaluation method aiming at a KVM virtualization server. The method comprises the steps of firstly at the application level, determining that the performance evaluation measure index of the KVM virtualization server is response time and throughput according to the quality of service parameter, namely QoS parameter, in a service level agreement and a common performance measure in the current actual application environment; then with the help of an open type queuing network model, establishing a virtualization server performance evaluation model through combining with the load characteristic of the virtualization server according to a resource scheduling and resource virtualization implementing mode in the KVM; and at last based on the performance evaluation mode, illustrating how to compute the performance measure index and evaluate the performance of a virtual machine in an Linux operation system. According to the method, the problem about evaluating the performance of the virtualization server in the KVM is solved, the performance evaluation efficiency is improved, the establishment of a complex performance testing environment is avoided, the performance evaluation cost is reduced, and the performance measures of main components in the virtualization server can be obtained, thus being capable of helping the user find system performance bottlenecks.

Description

technical field [0001] The invention relates to KVM virtualization technology, in particular to a method for performance evaluation of a virtualized server in KVM (Kernel-based Virtual Machine), which solves the performance evaluation problem of a virtual machine in a Linux environment and improves the performance evaluation efficiency of a virtual machine. Background technique [0002] In the 1960s, IBM tailored a time-sharing operating system for its mainframe to realize the sharing of the mainframe by multiple users, and proposed the concept of a hypervisor, and first proposed virtualization technology. In the 1980s In the early 1990s, with the development of hardware technology, independent servers with dedicated functions gradually replaced centralized computing, and the development of virtualization technology slowed down. At present, the utilization rate of server resources in traditional data centers is too low, and energy consumption is relatively large. Virtualizat...

Problems solved by technology

[0006] KVM is a new entrant in the field of server virtualization. It was merged into the Linux kernel in 2007 and became the default virtualization solution for Linux systems. It is closely related to the OpenStack cloud computing platform, which provides a huge space for the use of KVM. KVM It is gradually becoming a popular open source virtualization solution. At present, the performance evaluation of virtualized servers is mainly focused on the Xen virtualization platform, and there are few studies on the performance evaluation of virtualized servers in KVM.
