摘　　要：针对云计算环境下的虚拟机动态部署问题,提出了综合考虑系统负载均衡和宿主机利用率的虚拟机动态部署方法;首先,建立了云计算环境下虚拟机的部署模型,然后采用加权预测法预测宿主机的负载并采用阈值进行筛选,对通过阀值筛选的宿主机计算其与用户任务需求向量之间的距离,以选取目标宿主机进行虚拟机部署,对未通过筛选的宿主机进行虚拟机迁移以实现负载均衡和提高宿主机利用率;实验结果表明,文中方法有效地解决了云计算环境下虚拟机动态部署问题,负载离差最大值仅为0.0031,较其它方法能较大幅度地提高宿主机的利用率和实现系统负载均衡,具有很强的可行性。In order to solve the dynamic deployment for virtual machine, a dynamic deployment method considering the load balance of host and the working efficiency. Firstly, the deploy model in cloud computing was proposed, then the weighted prediction method was used to predict the load of host and the threshold was used to select the host, the distance between use task need vector and the selective hosts were calculated, the virtual machines in unselective hosts were migrated to realize the load balance and improve the utilization of host. The experiment shows the method in this paper can solve the virtual machine deploy problem, the maximum Load deviation is only 0. 0031, and compared with the other methods, it can improve the utilization of host and realize load balance with strong feasibility.
