KVM虚拟机综合性能测试与分析

Comprehensive Performance Test and Analysis of KVM Virtual Machine

虚拟机是由虚拟化层提供的独立虚拟计算机系统,其综合性能对虚拟机的使用至关重要。文章设计高性能模式和性能均衡模式下两种实验方案,对基于oVirt的KVM虚拟机的综合性能进行测试,并对比分析两种不同模式下虚拟机CPU、内存带宽、磁盘IO和网络带宽的性能表现。实验结果表明,在高性能模式下虚拟机内存和磁盘IO性能表现相对较优,可为实际应用中规划合适的虚拟机模式提供依据。

Virtual Machine is an independent virtual computer system provided by the virtualization layer,and its comprehensive performance is very important for the use of Virtual Machine.This paper designs two experimental schemes in high performance mode and performance balance mode,tests the comprehensive performance of KVM Virtual Machine based on oVirt,and compares and analyzes the performance representation of CPU,memory bandwidth,disk IO and network bandwidth of Virtual Machine in two different modes.The experimental results show that the performance of Virtual Machine memory and disk IO is relatively better in high performance mode,which can provide a basis for planning appropriate Virtual Machine mode in practical application.
