Virtualization technology provides the ability to transfer Virtual Machines (VM) between the physical systems using the technique of live migration mainly for improving the efficiency. Server consolidation through live migration is an efficient way towards energy conservation in cloud data centers. This paper is to prevent server sprawl, which refers to the usage of multiple-utilized servers in data centers incurring high system management cost. To prevent server sprawl, server consolidation aims at reducing the number of server machines used in the data centers by consolidating load and enhancing resource utilization of physical systems.
