摘　　要：传统虚拟机部署机制通常单一地依据宿主机当前的CPU状况来选择目标宿主机,从而引起负载不均衡。针对该问题,提出一种云平台中优化的虚拟机部署机制。建立宿主机自动选择模型,给出基于个性需求的宿主机自动选择策略,对宿主机后续负载状况进行预测,估算虚拟机的资源消耗。实验结果表明,该机制能在满足用户需求的基础上提高系统性能。Hosts are usually selected only based on hosts＇ current CPU conditions using traditional method.It brings load imbalance caused by the irrational use of resources.Aiming at this problem,this paper presents a virtual machine deployment mechanism in cloud platform.The model which can automatically select host is established.The automatic selection strategy is based on the individual needs,and it can predict follow-up load and resource consumption of virtual machines.Experimental results show that the mechanism can meet the users＇ requirement and improve the system performance.
