<P>PROBLEM TO BE SOLVED: To confirm an interrupt occurrence device from an OS regardless of the type of a device identification register. <P>SOLUTION: A virtual computer 2 which receives an interrupt signal by using a shared interrupt signal line 7 from devices 3A and 3B includes: an OS part 20 for transmitting a first confirmation signal to confirm the interrupt occurrence of the device 3A and a second confirmation signal to confirm the interrupt occurrence of the device 3B; and a virtual machine monitor 10 having an interrupt signal line 7 for transmitting the interrupt signals of the devices 3A and 3B, a shared interrupt determination table 11 for storing information relating to the devices 3A and 3B, a shared interrupt determination part 13 for transmitting an interrupt occurrence signal to the OS part 20 when receiving the interrupt signal, and for determining an interrupt occurrence device by referring to the shared interrupt determination table 11, and an interrupt occurrence simulation part 14 for receiving the first and second confirmation signals transmitted from the OS part 20, and for transmitting a response signal to the OS part 20 by simulating the devices 3A and 3B on the basis of the determination result of shared interrupt. <P>COPYRIGHT: (C)2013,JPO&INPIT |
