摘要:

针对云计算数据中心中虚拟机实时迁移时间过长的问题,提出了一种虚拟机快速实时迁移方法.通过对预拷贝模型进行公式化描述和性能分析,在预拷贝方法中增加了用于标记改动频繁内存页的页位图.在迁移过程中对改动频繁的内存页进行判断,将改动频繁的内存页标记到新增的页位图中,并只在最后一轮迭代中传输.实验结果证明,与传统的预拷贝方法相比,改进后的预拷贝方法明显地减少了迁移时间,达到了快速迁移虚拟机的目的.

Abstract:

A fast live migration method of virtual machine is brought up for problem of long total migration time of live virtual machine migration in cloud data center. Through the formal definition and the performance analysis of the pre-copy model, a bitmap page which marked those frequently updated pages is added in the pre-copy approach. By judge in the iteration process, those frequently updated pages are put into the page bitmap, and transmitted in the last round of the iteration process only. A contrast between the pre-copy approach and the fast pre-copy approach is given. The fast pre-copy approach can distinctly reduce the total migration time of live migration, and achieve the purpose of fast live virtual machine migration.

Key words: cloud computing, virtual machine, live migration, pre-copy approach
