Load-based controlling scheme of virtual machine migration

Playing a key role in system online maintenance and upgrade, dynamic resource management, fault tolerance and power management, virtual machine migration has attracted significant attention in recent years. This paper proposes a load-based controlling scheme of virtual machine migration to achieve a better system performance than existing methods in cloud computing environment. It concludes three parts, migration triggering module judging whether the migration process should be activated, host machine selecting module deciding which machine in the physical host should be migrated, destination host selecting module determining which network node is selected for migration destination. Simulations show that the proposed scheme efficiently avoids unnecessary migration, and reduces the amount of data transferred, as well as improves the system performance of load balancing across physical system.
