PROBLEM TO BE SOLVED: To improve efficiency by recognizing the server/client relation of a plurality of guest OSs and adjusting a time when a CPU is assigned to each guest OS, based on the relation. SOLUTION: When an arbitrary guest OS among guests OS310-0 to 310-3 functions as a client, and makes a request for processing to another guest OS, functioning as a server, a guest OS interface part 201 of a VMM 20 includes an interface to be used for notifying a VMM 20 of a server/client relation, indicating that the guest OS of the request origin of processing is a client, and that the guest OS of the request destination of processing is a server from the guest OS of the request origin. A guest OS scheduler 205 for the VMM 20 adjusts the time the CPU 110 is assigned to the guest OSs 310-0 to 310-3, based on the server/client relation which is notified by the interface.
