<P>PROBLEM TO BE SOLVED: To allow each OS to start using a new interrupt number in any arbitrary timing under an environment where a plurality of OSs operate, and to share the interrupt number among two or more OSs even when the interrupt number of which the use is to be newly started is used by the other OS already. <P>SOLUTION: A virtual computer monitor 200 has a function which specifies a guest OS which processes an interruption when there is the interruption including a shared interrupt number, and a guest OS 400 determines whether an interrupt number of which the use is to be newly started is being used by any other guest OS. If used by the other guest OS, the interrupt number is designated as the shared interrupt number and information making the shared interrupt number correspondent to the virtual computer monitor is set to an interrupt controller. An interrupt controller 120 causes the virtual computer monitor to specify the guest OS which processes the interruption in the case where the interrupt number included in the received interruption is corresponding to the shared interrupt number. <P>COPYRIGHT: (C)2012,JPO&INPIT |
