Cloud computing is a term that used for distributed computing, on a network.It is meant network-based services that these services are provided through virtual ISPs.Most of the old virtual machine migration techniques concentrated on the migration of a single virtual machine.These techniques are insufficient, when the whole virtual cluster needs to be migrated.In these methods, data replication in each round leads to many computational overheads.In this paper, a method is proposed for virtual machine migration from one data center to another.The proposed method uses the greedy algorithm for virtual machine selection.Virtual machines within a cluster are given priority, which reduces the total migration time of a cluster.This method is simulated in CloudSim tools in Eclipse.Simulation results show that the bandwidth parameter has the important role in the virtual machine migration.
