When notifying virtual machines of a change to shared data, it is impossible to realize power saving for the apparatus if always notifying a virtual machine in the power-saving state. The present invention is equipped with an inter-VM notification management unit 1242, a resuming judgment unit 1244 and a scheduled interruption time acquisition unit 1245, and when it is necessary to notify a virtual machine in the power-saving state, the resuming judgment unit 1244 judges whether to cause the virtual machine to return from the power saving state, based on the time until the interruption acquired by the scheduled interruption time acquisition unit 1245. With this structure, the present invention prevents unnecessary transitions between the states, and realizes the power saving for the apparatus.
