Most research on virtual machine (VM) migration focus on the issue of single VM migration by using the post-copy or pre-copy migration strategy.In this paper we focus on multiple VM migration, which becomes important when we have several cooperating VMs providing services, and propose an improved serial migration strategy that is based on the serial migration strategy.We then present the m mixed migration strategy that is based on the improved serial migration strategy and the parallel migration strategy.We conduct detailed simulation experiments to evaluate the performance of the m mixed migration strategy in terms of the migration time and the downtime.
