摘要
针对虚拟机迁移速度慢,且用时较长的问题,提出基于云计算的VMware虚拟化平台动态自适应迁移方法。通过云计算搭建VMware虚拟化平台,按照历史脏页率、数据抖动特性,获得运行业务特征及其网络带宽用量,并自适应调节带宽系数,合理分配网络带宽;根据内存大小、脏页速度与带宽传输速度制定物理资源迁移的约束条件,利用熵编码、字典编码、游程编码方法完成脏页内存的压缩,完成动态自适应迁移。实验结果表明,所提方法能够在物理资源有限条件下,合理利用带宽资源,缩小停机时间,提升虚拟机迁移效率,并保证运行业务的服务质量。
Aiming at the problem of slow and long migration time of virtual machines,a dynamic adaptive migration method of VMware virtualization platform based on cloud computing is proposed.The VMware virtualization platform is built through cloud computing.According to the historical dirty page rate and data jitter characteristics,the operating business characteristics and network bandwidth usage are obtained,and the bandwidth coefficient is adjusted adaptively to reasonably allocate network bandwidth;According to the size of memory,dirty page speed and bandwidth transmission speed,the constraints of physical resource migration are formulated.Entropy coding,dictionary coding and run-length coding are used to complete the compression of dirty page memory and complete dynamic adaptive migration.The experimental results show that the proposed method can make reasonable use of bandwidth resources,reduce downtime,improve the efficiency of virtual machine migration,and ensure the quality of service of running business under the condition of limited physical resources.
