Virtualization technology has become commonplace in modern data centers and cluster systems. Virtual Machine (VM) follow a technique called live migration which helps in migrating OS instances across distant physical data centers and clusters with high performance, improved resource management and fault tolerance. Moreover, live migration often allows workload movement with a short service downtime. But service levels of host operating system are likely to be negatively affected during a live VM migration because of service downtime. For this reason, a better understanding of its effects on system performance is highly desirable. So that correct algorithm can used to perform the live migration.
