摘要

A client system using a virtual machine includes: a physical server that includes a CPU, a memory, a bus, and a plurality of bus adapters, manages a plurality of guest OS by a host OS, and operates as a virtual machine. A plurality of input and output units are coupled to the plurality of bus adapters of the physical server respectively. A host OS of the physical server includes a configuration definition table that stores identification numbers of the input and output units in correspondence to guest OSs used by the input and output units. The host OS notifies a guest OS corresponding to an input unit of input instruction information from the input units with reference to the configuration definition table and outputs a processing result of a guest OS to an output unit corresponding to the guest OS.
