PROBLEM TO BE SOLVED: To hide, from a client terminal, the transfer of a virtual machine between data centers distant geographically.SOLUTION: A control device 50 notifies servers 11, 21 of starting transfer of a VM #1 and also instructs a communication device 41 to forward a packet transmitted by a client terminal 30 and destined to the VM #1 to communication devices 42, 43. On confirming the complete transfer of the VM #1 from the server 11 to the server 21, the control unit changes the setting of the communication device 41 so as not to forward a packet destined to the VM #1 to the communication device 42, and sets the communication device 42 so as not to forward a packet forwarded from the VM #1 to the client 30.SELECTED DRAWING: Figure 1 |
