Performance Analysis during Live Migration

The term virtualization describes the separation of a resource or request for a service from the underlying physical delivery of the service. Live migration of virtual machine relocates the memory and virtual device state of a VM from one physical machine to another with no noticeable downtime of the VM. The aim of this paper is to analyze the performance of the chosen workloads during live migration. The measurement and statistics of downtime and total migration time rate which are the key considerations for choosing a live migration approach will be recorded for drawing inferences. The workloads chosen will be intensive tasks on the system in terms of CPU utilization. Inference drawn from this analysis would be to propose which virtual machine should be migrated when the chosen workloads are running simultaneously on each virtual machine and CPU usage by all the running virtual machines exceeds a certain threshold.
