PROBLEM TO BE SOLVED: To switch a communication path for a moved VM to a newly established communication path without communication interruption in a network system.SOLUTION: In a network system including a first information processing device, a second information processing device connected to the first information processing device through a plurality of switch devices, and a third information processing device connected to the first information processing device through a plurality of switch devices, communication paths among the first information processing device, the second information processing device and the third information processing device are established on the basis of the control of a management device. A communication control method includes: establishing a first communication path from a first virtual machine provided in the first information processing device to a second virtual machine provided in the second information processing device; and before moving the second virtual machine from the second information processing device to the third information processing device, establishing a second communication path, which is different from the first communication path, from the first information processing device to the third information processing device. |
