摘要:

低能量消耗与物理资源的充分利用是绿色云数据中心构造的两个主要目标，需要采用虚拟机迁移模型来完成优化，为此提出了融合虚拟机选择和放置的虚拟机迁移模型INTER-VMM（Interrelation approach in virtual machine migration）。INTER-VMM设计了云数据中心的基于多维物理资源约束的能量消耗模型，是一种将主机负载检测、虚拟机选择及放置结合起来考虑的虚拟机迁移策略。在虚拟机选择中采用HPS（High CPU utilization selection）选择法，选择超负载物理主机上CPU利用率最高的一个虚拟机，让其进入候选迁移虚拟机列表中。在虚拟机放置中采用空间感知分配（Space aware placement， SAP）放置法，考虑了充分利用物理主机空余空间使用效率的方法。仿真结果表明，INTER-VMM比近几年来常见的虚拟机迁移策略具有更好的性能指标，对云服务提供商具有很好的参考价值。

Abstract:

Low energy consumption and full utilization of physical resources are two primary objectives for green cloud data construction， so a virtual machine migration model is required to complete the optimization. An interrelation approach in virtual machine migration（INTER-VMM） is proposed in this paper， which interrelated virtual machine selection and its placement. An energy consumption model based on multi-dimensional physical resources for cloud data centers is designed in INTER-VMM. It is a virtual machine migration strategy combining host detection， virtual machine selection and its placement. The CPU utilization selection（HPS） is adopted in virtual machine selection， which selects the virtual machine with the highest CPU utilization on the overloaded physical host and lets it enter the list of candidate migration virtual machine. The space aware placement （SAP） is adopted in virtual machine placement， considering the method of making full use of the spare time of the physical host. Simulation results show that INTER-VMM has better performance indices than those of common virtual machine migration strategies in recent years， which is valuable for cloud service providers.
