Efficient performance upsurge in live migration with downturn in the migration time and downtime

Abstract

Live migration is transferring the running virtual machine or application between different physical machines from one system to another. It is useful for resource management of data center. Pre-filter-copy algorithm is used to improve the bandwidth resource consumption and to reduce the migration time and down time. The main goal of pre-filter-copy algorithm is to identify the dirty pages. The dirty pages are frequently modified pages. A novel data filter is designed to filter the dirtied pages. There are three parameters which are migration time, downtime, and memory space. Virtual machine can be migrated from under loaded host to overloaded host so that load can be balanced. In downtime the hardware failures and software updation are tested. The memory space can be balanced by shutting down the systems which are at rest so that space can be reduced. The memory space is increased from 512 Mb to 1 Gb. The memory of the frame is increased to transfer more number of pages and also to increase the speed of the transaction. By reducing the migration time and downtime the performance can be increased.
