Address assignment method, computer, and recording medium having program recorded therein

A computer to be used as a physical machine that creates a virtual machine, comprising:

• a storing part storing address set information that indicates a set of addresses to be shared among a plurality of physical machines;
• a receiving part receiving use range information that indicates a range of use of addresses to be assigned in the set of addresses to a virtual network interface card in the virtual machine created by another physical machine sharing the set of addresses, the range of use being transmitted from the another physical machine via a network;
• a storage controlling part storing the use range information received by the receiving into the storing part;
• a use range setting part setting a range of use of addresses to be assigned to the virtual network interface card in the virtual machine to be created, based on the set of addresses and the range of use represented by the address set information stored in the storing part and the use range information, respectively;
• and
• a transmitting part transmitting use range information indicating the range of use set by the use range setting part to another physical machine via the network.

A computer-readable recording medium storing a program that causes a computer to perform operations, the computer being used as a physical machine that creates a virtual machine, said program causing the computer to execute:

• a receiving operation to receive use range information that indicates a range of use of addresses to be assigned in a set of addresses to a virtual network interface card in the virtual machine created by another physical machine sharing the set of addresses, the range of use being transmitted from the another physical machine via a network;
• a storage controlling operation to store the use range information received through the receiving operation, into a storing unit;
• a use range setting operation to set a range of use of addresses to be assigned to the virtual network interface card in the virtual machine to be created, based on the set of shared addresses and the range of use represented by the use range information stored in the storing unit;
• and
• a transmitting operation to transmit use range information indicating the range of use set through the use range setting operation, to another physical machine via the network.
