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
