The act of moving a running virtual machine (VM) from one physical host to another, without interruption to its services or resulting in downtime, is called virtual machine migration. Live virtual machine migration (LVMM) is a vital component of cloud computing that enables scalability, reliability, and load balancing capabilities in virtualized environments, with no apparent downtime for the end-user. This research paper outlines several LVMM methods and provide an analysis on the basis of downtime, total migration and total data transfer
