A Complete Theoretical Review on Virtual Machine Migration in Cloud Environment

Live migration of virtual machine is the key features of the virtualization. It’s allowing the administrator to move the virtual machine from one physical machine to another physical machine. This technique is widely used for the fault tolerance, load balancing, server maintenance and resource consolidation. Down time and the total migration time are two critical issues in the virtual machine migration, both should be minimize as possible. So the application running on the virtual machine will be suspended for negligible time. Virtual machine migration problem consist of four distinct steps. First step is to select the host from where VM migrated. After selecting the host next step is to select the VM which is migrated. Third step is to select the host where the migrated VM will be placed and the last step is to decide the method which is used to transfer the VM. In this paper we explain some exiting methodology for each steps After reading this paper you will have all basic knowledge regarding to the VM migration
