On the other hand, the computing paradigm is shifting to the multi-tenant ecosystems. Therefore, characterizing the power consumption on Virtual Machines(VMs), running in data center hosts is necessary to attain energy efficient cloud ecosystems. In this paper, we study the challenges should be addressed in VM power modeling in cloud service provisioning.
