摘要
随着服务器虚拟化及桌面虚拟化技术的普及,越来越多的高校选择将传统PC操作系统迁移到虚拟化环境,从而有效提高了硬件和软件利用率。而虚拟机的网络性能直接影响着用户体验,从网络性能评测指标出发,介绍了基于KVM+QEMU的虚拟机网络优化的一般方法,进一步分析探究了一种以SR-IOV模式为基础的虚拟机网络性能优化方案。实验结果表明,该方案提高了虚拟机系统的网络带宽,减少了网络延迟,整体性能提高了25%以上,有效提升了用户体验。
With the popularity of server and desktop virtualization technology, more and more colleges choose to migrate traditional PC OS to virtualization environment, which effectivelyimproves the utilization of hardware and software. The network performance of virtualmachine directly affects user experience, this article starts from network performanceevaluation index, in troduces the general way of virtual machine network optimization basedon KVM ＋ QEMU, then analyzes one performance optimization scheme of virtual machine networkbased on SR-IOV. The results of experiments shows that the scheme improves the system＇s network bandwidth and reduces the network latencyof the virtual machine, and overall performance is improved by more than 25 %, which effectively improves the user experience.
