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.
An input/output (I/O) device fault processing method of a virtual computer system having a plurality of virtual computers operative to run on a physical computer under control of a hypervisor, said plurality of virtual computers including a plurality of virtual user computers to be provided to users and a virtual management computer, and a physical I/O device for shared use by said plurality of virtual user computers under control of the hypervisor, wherein said method comprises the steps of:
A virtual computer system having a plurality of virtual computers operative to run on a physical computer under control of a virtual computer control means, said plurality of virtual computers including a plurality of virtual user computers to be provided to users and a virtual management computer, and a physical input/output (I/O) device for shared use by said plurality of virtual user computers under control of the virtual computer control means, wherein
