VIRTUAL COMPUTER CONTROL DEVICE AND VIRTUAL COMPUTER CONTROL METHOD

摘要

A virtual computer control device (100) that execution-controls a first type virtual computer A (210) and a second type virtual computer (220). The first type virtual computer A (210) has: a start detection unit (261) that detects if preparation is being made to start the use of a device in the virtual computer; and a start signal output unit (262) that outputs a start signal if the start detection unit (261) makes that detection. The second type virtual computer (220) has a device control unit (external storage device driver (273)) that sets the status of a device (external storage device (160)) to the normal status (power ON status), when a start signal is output from the start signal output unit (262), if the device (external storage device (160)) is in a low power consumption status (power OFF status).
