Division of arithmetic progression for virtual machines’ live migration
摘要
Abstract
The live migration of virtual machines was studied .The performances of the pre-copy algorithm , the post-copy algorithm and the hybrid-copy algorithm for memory migration in local area networks were analyzed , and then , on the basis of the improvement of the hybrid-copy algorithm , a technique for the live migration of virtual machines based on the division of arithmetic progression was presented .The technique divides the memory pages transmitted in the first round into many segments similar to the form of arithmetic progression , so the memory pages transmitted in the second round can be decreased .The experiments performed under different workloads showed that compared with the hybrid-copyalgorithm , the proposed technique reduced the time of synchronous memory bitmap by 25%, and decreased the pages of post-copy by 29%and the total migration time by 2.2%on average, improving and de-creased the performance of virtual machines ’ live migrationto some extent .关键词
