Virtual calculating machine system, virtual calculating machine control apparatus and virtual calculating machine control method

A virtual-calculating-machine-control-apparatus comprising:

• a virtual machine implementing device that implements one or a plurality of virtual machines by managing hardware resources;
• an appliance connection detection processing unit to detect that an appliance has been detected;
• a connected appliance notification processing unit to notify, using communication-connection-destination-information indicating a communication-connection-destination of each appliance, a communicatively connected virtual machine implementing device that the appliance has been connected, and to request the virtual machine implementing device to permit a connection;
• and
• a first input and output control unit to transmit first data to the appliance upon receipt of the first data to the appliance from the virtual machine implementing device which permits the connection, and to transmit the second data to the virtual machine implementing device which permits the connection according to the communication-connection-destination-information, wherein
• the communicatively connected virtual machine implementing device includes
• a second input and output control unit to transmit the second data to a second virtual machine provided by the communicatively connected virtual machine implementing device upon receipt of the second data from the appliance of the virtual machine implementing device, and to, upon receipt of the first data to the appliance from the second virtual machine, transmit the first data to the first appliance of the virtual machine implementing device, wherein
• when connection validity of the virtual machine implementing device is set to “Disabled” in identification information included in the communication-connection-destination-information, the first input and output control unit transmits the second data to the virtual machine upon receipt of the second data from the appliance,
• when the connection validity of the second virtual machine implementing device is set to “Enabled”, the first input and output control unit transmits to the communicatively connected virtual machine implementing device interrupt information indicating that the appliance is connected.

An execution method of a virtual calculating machine system where a first virtual machine implementing device that implements one or a plurality of first virtual machines by managing hardware resources, and a second virtual machine implementing device that implements one or a plurality of second virtual machines by managing hardware resources are communicatively connected, the method causing the first virtual machine implementing device to execute

• detecting that a first appliance has been connected,
• notifying, using communication-connection-destination-information indicating a communication-connection-destination of each appliance, the second virtual machine implementing device being a communication-connection-destination of the first appliance that the first appliance has been connected, and
• transmitting first data to the first appliance upon receipt of the first data to the first appliance from the second virtual machine implementing device, and transmitting second data to the second virtual machine implementing device according to the communication-connection-destination-information upon receipt of the second data from the first appliance, and
• the method causing the second virtual machine implementing device to execute
• determining, using identification information, whether to permit a connection for the first virtual machine implementing device notified that the first appliance has been connected when identification information of the first virtual machine implementing device is included as the identification information of a device for which the connection is permitted, and notifying the second virtual machine that the first appliance has been connected when the connection is permitted, and
• transmitting the second data to the second virtual machine according to the identification information upon receipt of the second data from the first appliance of the first virtual machine implementing device, and, upon receipt of the first data to the first appliance of the first virtual machine implementing device from the second virtual machine, transmitting the first data to the first appliance of the first virtual machine implementing device according to the identification information, wherein
• when connection validity of the second virtual machine implementing device is set to “Disabled” in the identification information included in the communication-connection-destination-information, the second data is transmitted to the first virtual machine,
• when the connection validity of the second virtual machine implementing device is set to “Enabled”, interrupt information indicating that the first appliance is connected is transmitted to the second virtual machine implementing device.

A control method of a virtual machine implementing device implementing one or a plurality of virtual machines by managing hardware resources, the method comprising:

• detecting that an appliance has been connected;
• notifying, using communication-connection-destination-information indicating a communication-connection-destination of each appliance, a communicatively connected virtual machine implementing device that the appliance has been connected, and requesting the virtual machine implementing device to permit a connection;
• and
• transmitting first data to the appliance upon receipt of the first data to the appliance from the virtual machine implementing device which permits the connection, and transmitting the second data to the virtual machine implementing device which permits the connection according to the communication-connection-destination-information upon receipt of the second data from the appliance, wherein
• the communicatively connected virtual machine implementing device includes
• an input and output control unit to transmit the second data to a second virtual machine provided by the communicatively connected virtual machine implementing device upon receipt of the second data from the appliance of the virtual machine implementing device, and to, upon receipt of the first data to the appliance from the second virtual machine, transmit the first data to the first appliance of the virtual machine implementing device, wherein
• when connection validity of the second virtual machine implementing device is set to “Disabled” in the identification information included in the communication-connection-destination-information, the second data is transmitted to the first virtual machine,
• when the connection validity of the second virtual machine implementing device is connected to “Enabled”, interrupt information indicating that the first appliance is connected is transmitted to the second virtual machine implementing device.
