摘要
在云计算环境中,有效的虚拟机动态迁移算法有助于降低能耗和SLA违反率。本文提出了一种改进的虚拟机动态迁移算法,通过双阈值策略、基于最小迁移代价的虚拟机选择策略和目标物理节点的概率选择策略来降低能耗,并降低SLA违反率。仿真实验表明,该方法在虚拟机动态迁移中能够降低系统的能源消耗,同时也降低了SLA违反率。
In cloud computing environment , a n effective live migration algorithm of virtual machine can greatly reduce energy consumption and the violation rate of SLA . This work proposes an improved virtual machine live migration algorithm ’ which adopts the double thresholds strategy ’ the virtual machineselection strategy based on the minimum cost of migration , and the probabilistic selection target physical nodes. The simulation experiments show that the proposed algorithm can reduce the system energy consumption and the SLA violation rate in the virtual machine live migration.
