Problems solved by technology
However, if the DHCP service is applied rigidly to the virtualization environment without considering the network characteristics of the virtual machine, it will cause disadvantages such as low server efficiency and heavy network load, which will cause a lot of inconvenience to the network management of multiple virtual machines, which is not easy. Meet the requirements of multi-virtual machines for efficient, dynamic and transparent management of resources

Embodiment Construction
[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0033] Such as figure 1 As shown, the network configuration method of the present invention includes the following steps:
[0034] (1) The virtual machine starts and sends a broadcast message to the network;
[0035] (2) The server of the physical machine parses the broadcast message, and judges whether the broadcast message is from its corresponding virtual machine; if the broadcast message is from its corresponding virtual machine, then proceed to step (3), otherwise discard the broadcast message;
[0036] (3) The server of the physical machine responds to the broadcast message;
[0037] (4) The server of the physical machine queries the network resource pool, performs network resource allocation according to the preset strategy, and returns the allocation result;
[0038] (5) If the allocation result shows that the resource allocation is successful, the...

The invention provides a network configuration method in virtual machine environment, which comprises the follow steps that: a virtual machine is started and sends broadcast messages to a network; the service end of a physical machine analyzes the broadcast messages and judges whether the broadcast messages are from the corresponding virtual machine or not; when the broadcast messages are from the corresponding virtual machine, the service end of the physical machine responds to the broadcast messages; the service end of the physical machine inquires a network resource pool, the network resource allocation is executed according to preset strategies, and the allocation results are returned; when the allocation results show that the resource allocation is successful, the service end of the physical machine generates network configuration parameters according to the allocation results; the service end of the physical machine sends the network configuration parameters to the virtual machine in the message broadcasting mode; the virtual machine configures the network according to the network configuration parameters; and the service end of the physical machine updates the state information of the network resource pool. The network configuration method has the advantages that the network of the virtual machine can be effectively configured, the network overhead is reduced, and simultaneously, good transparency and expandability are also realized.
Description
technical field [0001] The present invention relates to the technical field of virtual machines, and more specifically, the present invention relates to a network configuration method in a virtual machine environment. Background technique [0002] A Dynamic Host Configuration Protocol (DHCP for short) is widely used to manage a physical local area network. However, if the DHCP service is applied rigidly to the virtualization environment without considering the network characteristics of the virtual machine, it will cause disadvantages such as low server efficiency and heavy network load, which will cause a lot of inconvenience to the network management of multiple virtual machines, and will not be It meets the requirements of multi-virtual machines for efficient, dynamic and transparent management of resources. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a network configuration method in a virtual machine environm...
