Method and system for automatic assignment and preservation of network configuration for a virtual machine

摘要

The disclosure herein describes a system, which provides network configuration to a respective network adapter of a large number of cloned virtual machines. During operation, the system stores one or more network identifiers assignable to a network adapter of a cloned virtual machine in a pool of virtual machines cloned from a parent virtual machine. A respective network identifier corresponds to a respective network configuration. The system then determines whether a network identifier for a network adapter of a cloned virtual machine is available. If so, the system assigns the network identifier to the network adapter in response to the network identifier being available, thereby associating the network adapter with the corresponding network configuration.

1. A computer-implemented method for providing network configuration to a respective network adapter of a number of cloned virtual machines, comprising:
storing in a data structure one or more network identifiers assignable to a network adapter of a cloned virtual machine in a pool of virtual machines cloned from a parent virtual machine, wherein a network identifier comprises a portion of an Internet Protocol (IP) address that identifies a network; determining availability of a network identifier from the data structure for the network adapter of the cloned virtual machine; and assigning the network identifier to the network adapter in response to the network identifier being available, thereby associating the network adapter with the corresponding network configuration.
