Mature virtualisation technology makes the cloud computing software architecture be able to manage and use hardware resources flexibly,efficiently and sufficiently. The migration of virtual machine is the key technology to realise dynamic resource management,as well as the important prerequisite for guaranteeing the load balancing and high availability of cloud computing platform. We present a heuristic migrationmethod which is based on virtual machine load fluctuations prediction. By analysing the fluctuations and balance situation of virtual machine load,we design a heuristic method to predict the load point of virtual machine and the turnaround time of load fluctuations. It is demonstrated through experimental data that the method is strong in adaptability,can effectively improve the efficiency of independent migrationof virtual machine,and achieves the goal of assisted virtual machine migration.
