PROBLEM TO BE SOLVED: To allow a fault determination part of a guest computer to detect a simulated fault in a virtual computer system in which semi-virtualization technology is applied.SOLUTION: The virtual computer system has an H/W fault operation tool 310 in which H/W fault information 441 defining information on faults requiring simulation is input. A front end driver 420 of a guest OS 400 includes a common memory 430 to be shared with a virtual machine monitor 210, a fault information table 440 stored in the common memory 430, a fault determination part 450 for determining whether the H/W fault information 441 has been set in the fault information table 440, and a fault simulation part 451 for simulating a fault on the basis of the H/W fault information 441 when the fault determination part 450 determines that the H/W fault information 441 has been set. |
