Method for power conservation in virtualized environments

摘要

A system and method for enabling power conservation when making placement and relocation decisions. More specifically, a virtualized environment power conservation module enables power conservation when making placement and relocation decisions within a virtual environment. The virtualized environment power conservation module assigns virtual machines among a group of physical hosts in order to minimize the net power consumption. The virtualized environment power conservation module makes use of server power profile or real time power consumption data to make power consumption aware Virtual Machine assignment decisions. In certain embodiments, a server system exposes real power consumption (e.g. System Watts, Cumulative kWh. etc.) via system management interfaces. Additionally, in certain embodiments, the server systems may expose real power consumption via standard power profiles. These systems leverage PMBus-enabled power supplies to read the power metric information.

1. A method for enabling power conservation within a virtual environment comprising:
determining power consumption of a plurality of virtual machines within the virtual environment, the determining comprising using server power profile data and real time power consumption data to determine power consumption to each of the plurality of virtual machines; assigning some or all of the plurality of virtual machines to a particular physical host based upon the power consumption of each of the plurality of virtual machines, the assigning virtual machines to the group of physical hosts minimizing net power consumption of the virtual environment, the assigning comprising making power consumption aware virtual machine assignment decisions based upon using server power profile data and real time power consumption data; and wherein the plurality of virtual machines are executing within a server system; the server system further includes a plurality of controllable power supplies, the plurality of controllable power supplies comprising respective Power Management Bus (PMBus) enabled power supplies, the PMBus enabled power supplies enabling power metric information to be read from the PMBus enabled power supplies via a power management bus; and, each of the plurality of controllable power supplies are controlled when assigning the virtual machines to enable power conservation when making placement and relocation decisions within a virtual environment.
