Abstract
The system of controlling CPUs in a virtual computer system in which virtual computers are operated by assigning CPU resources to a plurality of virtual computers (guest VMs) according to optional ratios aims at effectively utilizing actual CPUs with predetermined assignment ratios duly maintained even if the CPU assignment ratios are unequally set among a plurality of guest VMs. The present invention comprises an operation counter for storing the number of times of operations in which each guest VM is successfully assigned CPU resources according to a predetermined assignment ratio, and an assignment order control unit for arranging pointer information on guest VMs in order of number of times of operations indicated by the operation counter, the pointer information being arranged in the ready queue where the current priority in the CPU resource assignment is set using the pointer information on each VM, and for arranging the pointer information on guest VMs in high-to-low order of assignment ratio for those which indicate the same number of times of operations.
