云环境下虚拟机集群迁移策略研究
Study on Virtual Cluster Migration Strategy in Cloud Environment
摘要
Abstract
In allusion of problem of wasted energy consumption in the data center caused by its low resource utilization and imbalanced load,a virtual machine migration algorithm based on dual threshold and resource demand for relevance matching is proposed,which a-dopts two-threshold method to trigger the virtual machine migration strategy and avoids frequent VM migration by reducing the number of virtual machine migrations by the double-threshold triggered strategy. According to the resource utilization,bandwidth memory ratio and the relevance with server resource for each virtual machine,the data center has reduced the migration cost and guarantee the quality of service,which it can release more server resources and can determine the server to be migrated by the quantity of migration and the degree of resource matching meanwhile. The simulation results show that it has effectively reduced cost of virtual machine migration and promo-ted system resource utilization,with certain improvement in reducing the SLA breach,avoiding most virtual machine migration to the clus-ter effect formed by the same server.关键词
