<P>PROBLEM TO BE SOLVED: To prevent a physical computer on which a plurality of virtual computers operate from stopping due to the fact that IO processing under preparation via VF continues to remain when the virtual computers operate on the physical computer while sharing an IO device. <P>SOLUTION: Disclosed is a control method of a computer device including: a storage part for storing a first virtual computer, a second virtual computer and a hypervisor for managing the first and second virtual computers; and a shared IO device to be used by the first and second virtual computers. The shared IO device includes a physical IO device and a virtual IO device. When the physical IO device stops, the virtual IO device stops, and when detecting a signal to stop the physical IO device transmitted by the first virtual computer, the hypervisor stops the physical IO device with the completion of a processing request transmitted by the second virtual computer to the virtual IO device as a trigger. <P>COPYRIGHT: (C)2013,JPO&INPIT |
