• and
• a control information output unit configured to output any one of the input destination information and the output enable information;
• one specific operating system among the plurality of operating systems which operate on the host system comprises:
• an input device controller configured to specify, by using the outputted input destination information, an input destination operating system to which information inputted from the input device is inputted, and to input the inputted information to the input destination operating system;
• and
• an output device controller configured to specify, by using the outputted output enable information, an operating system capable of outputting information to the output device, and to output the information received from the operating system to the output device;
• the input destination information includes at least information for specifying the input destination operating system to which information inputted from the input device is inputted;
• and
• the output enable information includes at least information for specifying whether or not each of the plurality of operating systems can output information to the output device.
