Abstract: A Scheduler is main role to schedule number of virtual machines VMs as per virtual machines request VMr from cloud consumer. Scheduler schedules number of virtual machines VMs requests call Lease such as conserve maximum amount of energy, achieves greater scale of load balancing and less resource utilization with less time less efficiency. In this paper we review scheduling schemes in private cloud environments which is recently proposed in our previous work on base of Energy Efficient.

Keywords: VM, VMr, Energy Efficient, VMs, Host, Guest.
