摘要
传统基于Hypervisor模型的云计算资源调度方法存在长时间得不到调度,调度性能低的问题。针对该问题,设计基于容器技术的云计算资源合理调度方法,设计了调度系统的架构以及调度流程。详细说明了虚拟机迁移时间判断流程以及被迁移虚拟机选择流程。采用Migrate方法完成虚拟机的迁移,资源统计过程通过调用Libvirt的接口实现通信,并通过近似的方式运算虚拟机CPU使用率,降低了云计算资源调度时的数据中心能耗。经过测试表明,所提方法稳定性高,总体性能优,达到了预期目标。
As the traditional cloud computing resource scheduling method based on the Hypervisor model has long scheduling delay and low scheduling performance,a cloud computing resource scheduling method based on the container technology is proposed,and the architecture and dispatch process of the scheduling system are designed.The judging process of virtual machine migration time and the selection process of the migrated virtual machine are elaborated.The Migrate method is adopted to accomplish the virtual machine migration.The Libvirt interface is invoked to realize communication during the resource statistical process.The CPU utilization rate of the virtual machine is obtained by means of approximate computations,which reduces energy consumption of the data center during cloud computing resource scheduling.The test results show that the proposed method has high stability and excellent total performance,and has achieved the anticipated goal.
