摘要 以虚拟机历史运行轨迹为依据,首先探讨虚拟机迁移对系统稳定性的影响。立足个体运行轨迹分布函数,提出基于心跳幅度的虚拟机动态迁移选择算法。该算法突破了传统以所有节点整体分布函数为基础的统计分析模型,充分挖掘并利用了个体运行特征,有效提升虚拟机迁移选择的合理性和整个虚拟环境的服务效率。最后,以实验为基础,对算法的有用性和有效性进行分析与验证。 According to the running track of virtual Machine, this paper firstly discusses the effect of vir- tual machine migration for system stability. Moreover, it put forward virtual machine dynamic selection algo- rithm based on heartbeat scope using the running track distribution function of each VM. This algorithm made a breakthrough to statistic analysis model based on the distribution function of all VMs, and fully excavates the running track of individual VM; all these improve the reasonability of VM migration selection and the Qos of entire virtual environments. Finally, it validates the usefulness and efficiency of this algorithm by experiment.
