Abstract
A virtual machine system includes a virtual battery manager, a discharge calculator, and a discharger. The virtual battery manager manages a virtual battery for running a virtual machine. The virtual battery holds electric energy used by the virtual machine. The virtual battery is capable of discharging and being charged. The discharge calculator calculates a discharged amount of the virtual battery by calculating energy consumption of the virtual machine with reference to a consumption policy and a consumption allocation table when a resource quota for the virtual machine satisfies a predefined condition for discharging. The consumption policy defines a maximum amount of total energy consumption of the plurality of virtual machines. The consumption allocation table contains an allocated ratio of energy consumption for each of the plurality of virtual machines. The discharger decreases a battery level of the virtual battery.
