Abstract
A method for measurement-based power and energy accounting for virtual machines distributed among at least one hosting device is disclosed. The method comprising determining an energy for the hosting device during a first time interval and a second time interval, partitioning a difference in the determined energy among virtual machines within a plurality of regions of the hosting device, determining a level of activity of each of the resources in each virtual machine within a corresponding one of the regions, determining an energy of each resource in each corresponding virtual machine wherein energy associated with resources shared among an plurality of virtual machines are allocated to a corresponding one of the virtual machines based on a number of requests made to the shared resource by the corresponding virtual machine, determining a total energy for each of the virtual machines in corresponding regions based on a level of activity of the virtual machine and the energy associated with the corresponding shared resources, and determining a power for each of the virtual machines by dividing the determined total energy by a length of the time interval.
