PURPOSE:To reduce the overhead of a virtual computer control program and to improve the accuracy of a timer by using the timer to execute the CPU timer processing of the virtual computer. CONSTITUTION:For a specific virtual computer VM, CPU timers (VM timers) 16-19 to be exclusively used for the VM, steps for executing start/stop of the timers, assigning to the specific VM and releasing the assignmant and a step for checking the assigning state of the timers are prepared. Since the CPU timer control processing for the VM is executed by using the VM timers 16-19, it is unnecesary to consider VM dispatching time slice processing by the virtual computer control program. |
