1. In a virtual machine system in which a plurality of virtual machines defined by users are operated for the users on a physical machine under a control program, a CPU power adjustment method comprising the steps of:
storing arrangement information for said plurality of virtual machines in an arrangement information storage of said virtual machine system; and
storing a CPU power coefficient in a CPU power storage of said virtual machine system, said CPU power coefficient indicating a CPU power rate of said virtual machine system assigned to said plurality of virtual machines;
wherein said arrangement information includes user defined service rates, and
wherein said method further comprises under said control program the steps of:
entering each user-defined virtual machine in said arrangement information storage; and
assigning a CPU service rate determined based on said CPU power coefficient multiplied by a user defined service rate of a user-defined virtual machine to activate said user-defined virtual machine.
