摘　　要：虚拟机的动态整合是提高云计算物理资源利用率和降低云数据中心能耗的有效途径。在分析云计算环境下虚拟机动态整合的相关研究进展及现有关键技术的基础上,给出云计算的体系结构;详细讨论能耗、服务质量(quality of service,QoS)、服务等级协议(service level agreement,SLA)和虚拟机迁移成本4个指标,并提出总体优化目标;根据虚拟机动态整合的三个步骤探讨相关研究方法和关键技术,并从能耗与性能优化的角度进行分析;指出目前研究中的重点问题,并对动态整合策略、能效与性能的折中、QoS和SLA、资源分配和安全性等方面的研究进行展望。The dynamic consolidation of virtual machine （VM） is an effective way to improve the physical resource utilization in Cloud computing and reduce the energy consumption of the Cloud data centers. The related research progress of VM dynamic consolidation and the existing key technologies in Cloud computing are analyzed. First of all, the architecture of Cloud computing is given. Secondly, four indicators including energy consumption, QoS, SLA and VM migration cost, and proposes the optimization goal are discussed. Moreover, the research methods and key technologies according to the three steps of VM dynamic consolidation are discussed, and the view of optimization of energy consumption and performance is analyzed. Finally, the key problems are described, and the research prospect for the future work is put forward, including dynamic consolidation policy, the compromise between energy efficiency and performance, QoS and SLA, resource allocation and security.
