Abstract:
1. A computer system using a virtual machine for control by a client device comprising: a physical server that includes a CPU, a memory, a bus, and a plurality of bus adapters, includes a host operating system (OS) that manages a plurality of guest OSs, and the physical server operates as a virtual machine to cause a virtual machine monitor (VMM) to divide a physical resource including at least the CPU and the memory into virtual resources, and for the VMM to allocate the physical resource to the guest OSs on the divided virtual resource basis; a plurality of input units that are coupled to the plurality of bus adapters of the physical server respectively and are operable as client devices by users; a plurality of output units that are coupled to the plurality of bus adapters of the physical server respectively and are as client devices by users, wherein the host OS of the physical server includes a configuration definition table that stores identification numbers of the input and output units in correspondence with respective guest OSs used by the input and output units, and the host OS receives and notifies a guest OS of input instruction information from an input unit that corresponds to the guest OS with reference to the configuration definition table and receives and outputs a processing result of a guest OS to an output unit that corresponds to the guest OS with reference to the configuration definition table.
