摘　　要：在openstack云环境下通过对网卡I/O、处理器、内存和磁盘I/O几个方面进行对比分析,比较了KVM虚拟机和物理机的性能差距。最后根据分析结果得出了KVM虚拟机更适合于网络I/O、内存和处理器密集型任务,而不适合磁盘I/O密集型任务的结论 ,并发现随着虚拟机数量的增加网卡I/O和磁盘I/O的性能呈直线下降。In this paper, the openstack cloud environment according to the analysis of the network I/O, CPU, memory and disk I/O aspects compares the performance gap between the KVM virtual machine and the physical machine. Finally , according to the results of the KVM virtual machine is more suitable for network I/O, memory and CPU intensive tasks, but not for disk I/O intensive tasks conclusion. And found that with the increasing number of virtual machine network I/O and disk I/O performance decreased linearly.
