Abstract

PURPOSE:To effectively utilize the resources of a processor by supplying power to the resources correspondingly to the operation status of a virtual machine. CONSTITUTION:The resource data (the number of instruction processors, the number of MS units, etc.) of a processor which can be used in each virtual machine and individually controlled at its power supply are stored in a main storage device (MS) 111. When an operator commands the n-th virtual machine to stop, a service processor (SVP) 102 stores the machine number of the virtual machine to be stopped in the MS 111 and informs the stop of the n-th virtual machine to a control program by interruption. The control program refers to the resource data, disconnects the processor resources of the virtual machine to be stopped and turns off its power supply.

In process 706, the control program
A power supply stop request for the processor resource used by the virtual machine to be stopped is sent to the SVP 102 via the SVU 109 by a control program dedicated command. SV
In step 707, the P102 powers off the processing device resource designated by the control program.

Further, in the case where each virtual computer is scheduled and operated in advance, that is, in a virtual computer system in which each virtual computer is automatically stopped at a predetermined time, for example, it is not necessary to specify the stop by the operator. The control program executes the processing 708, and performs the processing for stopping the power supply of the processing device resources of the virtual machine that is automatically stopped.
