A HYBRID APPROACH FOR REDUCING DOWNTIME, MIGRATION TIME AND ENERGY CONSUMPTION OF LIVE VM MIGRATION.

Abstract

In this paper we discuss a hybrid approach of live VM migration that evaluates the hosts across the LAN. Here the best of both Pre and post copy methods are to be evaluated using the hybrid approach. Later the pre copy approach used, spawn the VM on destination host after that CPU state and memory is transferred and after transferring processor state the opposite work has to be done. In our approach we used checkpoint mechanism for recovery of page faults occurs over the network while transferring the data over the VM. We propose a method that uses hybrid approach of live VM migration with addition a new data recovery mechanism. This recovery mechanism utilizes checkpoint and also in this the load balancing on individual machine has been done. In results 20% to 30% improvement has been seen and also it is better implementation over pre and post copy mechanism.
