An information processing device includes an external connection unit which connects to an external device; and a communication control unit which obtains data from a first virtual machine, transmits the data to a second virtual machine, and transmits, to the external connection unit, transmission completion information indicating that the data is already transmitted to the second virtual machine. The external connection unit (i) determines, based on the transmission completion information, whether or not a virtual machine is the second virtual machine to which the data is already transmitted, when the external connection unit receives, from the virtual machine, a request for a connection to the external device, and (ii) permits a connection between the virtual machine and the external device, when the external connection unit determines that the virtual machine is not the second virtual machine to which the data is already transmitted.
