Cloud computing enjoys the many attractive attributes of virtualization technology, such as consolidation, isolation, migration and suspend/resume support.In this model computing, some desirable features scalability are provided by means a new type building blocks called virtual machines (VMs).As with any other construction block, VMs have their own scheduling challenges advantages.This paper presents major differences between schedulable processes explains why traditional techniques used in operating systems to schedule or threads not suited VMs.New help co-scheduling resources concurrent environment proposed simulated on an extension CloudSim simulator.Simulation results processor show comparatively higher system performance than methods that do use co-scheduling.
