Abstract
An input/output (I/O) device fault processing method for executing, without contradiction, fault recovery processing of a physical I/O device which is commonly used or shared by a plurality of virtual computers in such a way that no influence is exerted on a virtual computer which does not presently use the shared I/O device is disclosed. A hypervisor performs fault monitoring of the physical I/O device. Upon occurrence of an operation failure, this failure is detected and notified to a virtual management computer. In responding to receipt of the notice, the virtual management computer performs the fault recovery processing of the physical I/O device.
