Zusammenfassung:A computer system enables two virtual machines with use of two virtual CPUs. The computer system includes a CPU that is allocated to the virtual CPU when the virtual CPU performs computer processing of the virtual machine other than timer processing; a tick CPU that is dedicated to timer processing and is allocated to the virtual CPU upon receiving an interrupt request (tick interrupt) for causing the virtual CPU to perform timer processing of the virtual machine; and interrupt controller that issues the tick interrupt to the tick CPU.
