PURPOSE:To maintain the distribution ratio of designated CPU resources and to efficiently utilize actual CPU even if the CPU distribution is unequal concerning the CPU control system of a virtual computer system where the CPU resources are distributed to plural virtual computers in the required ratio so as to permit the virtual computer to execute an operation. CONSTITUTION:A system is provided in a CPU assignment information area 16, an operation counter 20 stores a time for digesting the distributed quantity of the designated CPU resources at every guest (VM10-1 to 10-n), the distribution order of the CPU resources in the guests VM10-1 to 10-n of a ready queue 18 is arranged in order of the operation times of the operation counter 20 from a small number by a distribution order control means 22, the CPU distribution of the guests VM10-1 to 10-n is executed in order of the distribution ratio from the large number when the operation times of the operation counter 20 are same and the CPU distribution of the guests VM10-1 to 10-n is executed in order of the operation times from the small number when the operation times are different. |
