INFORMATION PROCESSING DEVICE AND COMMUNICATION CONTROL METHOD
First Claim
1. An information processing device where a host virtual machine and N guest virtual machines are allocated to a plurality of logically divided computing resources and operating systems run in the host virtual machine and the N guest virtual machines concurrently, respectively, and the information processing device is connected to a network by a network interface, whereinthe host virtual machine comprises:
- a virtual bridge connection module configured to virtually connect one guest virtual machine selected from the N guest virtual machines and the network by bridge connection;
a conversion modules provided in association with the N−
1 guest virtual machines not connected to the network virtually by bridge connection and an application that runs on the host virtual machine, and configure to convert packets transmitted from the N−
1 guest virtual machines and the application that runs on the host virtual machine to packets of a virtual private network (VPN) protocol; and
a packet allocation module configured to detect a destination of the packets received from the network, to allocate the received packets to the virtual bridge connection module in a case where the detected destination is the one guest virtual machine, and to convert the packets of the VPN protocol received from the network to original packets and to allocate the converted packets to the detected destination in a case where the detected destination is any of the N−
1 guest virtual machines and the application that runs on the host virtual machine.

Abstract
According to one embodiment, the host virtual machine includes a virtual bridge connection module configure to virtually connect one guest virtual machine and the network by bridge connection, a conversion modules configure to convert packets transmitted from the another guest virtual machines and the application to packets of a virtual private network (VPN) protocol, and a packet allocation module configure to detect a destination of the packets received from the network, to allocate the received packets to the virtual bridge connection module in a case where the detected destination is the one guest virtual machine, and to convert the packets of the VPN protocol received from the network to original packets and to allocate the converted packets to the detected destination in a case where the detected destination is any of the N−1 guest virtual machines and the application that runs on the host virtual machine.
