Abstract: A power supply includes a virtual machine state acquisition unit and a virtual machine management unit. The virtual machine state acquisition unit is configured to: send each of the virtual host computers in virtual host list data a request to acquire information on a virtual machine run in emulation by the virtual host computer; acquire, from each of the virtual host computers, the information on the virtual machine run in emulation by the virtual host computer; and create virtual machine management data in which an identifier of the virtual host computer, an identifier of the virtual machine thereof, and the acquired information on the virtual machine are associated with each other. The virtual machine management unit is configured to read the virtual machine management data and input a command related to a virtual power source of the virtual machine.

Abstract: An information processing device stores, in a storage device, command execution user data associating an attribute of a command with a name of a user entitled to execute the command. When execution of the command is requested, a service of the information processing device extracts, from the command execution user data, a name of a user entitled to execute the requested command and executes the command with the extracted user name.

Abstract: A first power supply is configured to feed power to a computer. The power supply includes a virtual machine management unit configured to transmit an instruction to any one of a second virtual host that is executed on the computer and a fourth virtual machine that is run in the second virtual host. Here, the fourth virtual machine is configured to control a virtualization management system including virtual hosts different from the second virtual host.

Abstract: A power supply includes a storage device and a virtual machine power data transfer unit. The storage device is configured to store virtual machine power management data in which an identifier of a virtual machine run in emulation by a virtual host computer fed with power from the power supply, and power information on the virtual machine are associated with each other. The virtual machine power data transfer unit is configured to, when a virtualization management server migrates the virtual machine run in emulation by the virtual host computer fed with power from the power supply to a migration destination virtual host computer fed with power from a different power supply, extract the power information on the migrated virtual machine out of the virtual machine power management data, and transfer the power information to the different power supply.

Abstract: A power supply for feeding power to a computer comprises an instruction acquisition unit configured to acquire an identifier of a virtual machine and an instruction for the virtual machine, the virtual machine being run in emulation by a virtual host executed on the computer; and a virtual machine management unit configured to input an operation instruction for the virtual machine to the virtual machine on the basis of the acquisition by the instruction acquisition unit.

Abstract: A power supply is used in combination with networked first and second hosts with a virtual machine implemented on the first host. The power supply is comprised of: a memory; an outlet part linked with outlets respectively supplying electricity to the hosts; a communication interface linked with the hosts; a controller linked with the memory, the outlet part and the communication interface; a migration process located on the memory, wherein the migration process causes the communication interface to send a migration instruction to the first host, the migration instruction causing migration of the virtual machine to the second host; and a shut-down process located on the memory, wherein the shut-down process causes the communication interface to send a shut-down instruction to the first host, the shut-down instruction causing shut-down of the first host.
