摘要： 为降低大规模云数据中心的能量消耗，并在一定程度上实现资源负载均衡，提出一种基于虚拟机迁移的方法LBES。该方法综合考虑多种资源负载情况以及群聚冲突等问题，对虚拟机迁移过程的3个关键步骤进行分析，给出相应的策略，并在云模拟器中得到实现。实验结果表明，在物理节点负载分布严重不平衡的情况下，该方法比其他算法的性能更优。

Abstract: In order to reduce energy consumption of large-scale data centers and realize load balancing to some extent, a method called Load Balancing and Energy Saving(LBES) based on Virtual Machine(VM) migration is introduced in this paper. It considers some problems such as the load situation of many kinds of resources, clustering conflict and so on, analyzes three critical procedures in the process of VM migration primarily and presents correspondent strategies. It comes true in Cloudsim. Experimental results show that this method is more excellent than other methods in performance, in the case of great imbalance of host machine load distribution.

Key words: cloud data center, Virtual Machine(VM) migration, load balancing, energy-consumption reducing, clustering conflict, Cloudsim
