Abstract: A computer system comprises cloud infrastructures including computers including a hypervisor manages a VM. The hypervisor includes a duplication correction virtual machine operating thereon, the duplication correction virtual machine controls communication of a duplication virtual machine to which a duplication MAC address assigned. Each of the cloud infrastructures includes a MAC address duplication monitoring module for monitoring duplication of the MAC address. The MAC address duplication monitoring module generates a translated MAC address in a case of detecting duplication of the MAC addresses; and transmits a duplication correction request including the translated MAC address to one of the computers on which the duplication virtual machine operates. The duplication correction virtual machine generates translation information in a case of receiving the duplication correction request, and controls communication between the duplication virtual machine and another virtual machine by using the translation information.
