摘要：针对当前虚拟机迁移算法物理节点负载不均衡、能耗高、SLA违反率高等问题,提出了一种改进的基于云计算的在线迁移算法.构建了在线迁移算法模型和虚拟机负载评估向量,依据各物理节点的CPU占用率、内存占用率和带宽占用率,来确定迁移时机、需要迁移的源物理节点和目标物理节点.仿真模拟环境实验表明,本算法在虚拟机在线迁移中能够大幅度地提高物理节点的负载均衡,同时使SLA违反率和云计算数据中心能耗降到最小.
For the current virtual machine migration algorithm is likely to cause physical node load imbalance,high energy consumption,SLA violation rate and other issues,a new cloud computing based online migration algorithm was proposed. An online migration algorithm model and virtual machine loads assessment vector were built,according to the CPU utilization,memory utilization and bandwidth utilization for each physical node to determine migration timing,source physical nodes which needed to migrate and the target physical nodes. The simulation of environmental testing showed that the proposed algorithm in a virtual machine live migration could greatly improve load balancing of the physical nodes,and meanwhile reduce the SLA violation rate and cloud computing data center power consumption to a minimum.
