Abstract
A virtual computer system has a plurality of virtual computers and a virtual computer monitor for monitoring the virtual computers and for providing translation information describing the relationship between a virtual identification of the input/output apparatus structure to be recognized by the virtual computers and a physical identification to be actually used by the input/output apparatus structure. A hardware dynamically creates a subchannel necessary for performing an input/output process of the virtual computers and translation information when the virtual computer monitor provides the translation information to the hardware. The hardware translates the virtual identification to the physical identification based on the translation information when the virtual computer issues the input/output instruction, and for identifying the subchannel, thereby performing the input/output process. The hardware also translates the physical identification of the control block to a virtual identification to be used by the virtual computer when an input/output interruption is generated, by using the subchannel by the input/output apparatus, thereby providing an input/output interruption to the virtual computer.
