This embodiment provides a method for configuring a network adapter of a virtual machine. FIG. 2 is a flowchart of a method for configuring a network adapter of a virtual machine according to an embodiment of the present application. As shown in FIG. 2 , the flowchart includes the following steps:

Step S201, after the virtual machine is started, the communication state of the network adapter of the virtual machine is detected.

In this embodiment, the virtual machine may be a Linux or Windows system, or may be other operating systems based on the virtual machine technology.

Step S202, in the case of detecting that the communication state of the network adapter of the virtual machine is abnormal, obtain the network configuration information of the real host where the virtual machine is located.

Step S203, configure the configuration file of the network adapter according to the network configuration information.

Step S204: Restart the service corresponding to the network adapter to make the configuration file of the network adapter take effect.

In this embodiment, the function of restarting the service corresponding to the network adapter is that the installation of some programs needs to rewrite the computer system registry, and the service corresponding to the network adapter can be used normally after restarting. At the same time, various network parameters such as the network IP address and subnet mask will change during the running of the script. Restarting the service corresponding to the network adapter can obtain such parameter information again. The function of restarting the service corresponding to the network adapter is realized through certain computer instructions. The above-mentioned computer instructions include, but are not limited to, network restart instructions, root instructions, and other program instructions capable of restarting the service corresponding to the network adapter of the computer system.

in some of these embodiments. The network configuration information of the real host at least includes: the physical address of the network adapter, the name of the network adapter, the type of the network adapter, and the startup configuration information of the service corresponding to the network adapter.

In some of the embodiments, step S202 includes: in the case of detecting that the communication state of the network adapter of the virtual machine is abnormal, obtaining the network configuration information of the real host by executing the ip addr command. In this embodiment, the script obtains the network configuration information of the real host through the ip addr command, which is convenient to compare the network configuration information of the real host with the current network configuration information in the subsequent steps to determine whether the two are consistent, and make a decision according to the judgment situation. Different processing ensures that the network configuration information of the virtual machine is always correct and ensures the normal communication of the virtual machine.

In some of the embodiments, a virtual machine (Virtual Machine) refers to a complete computer system simulated by software with complete hardware system functions and running in a completely isolated environment. The network uses physical links to connect isolated workstations or hosts together to form data links, so as to achieve the purpose of resource sharing and communication. Communication is the exchange and transmission of information between people through a certain medium. Network communication is to connect various isolated devices through the network, and realize the communication between people, people and computers, and computers and computers through information exchange. By generating a new virtual image of the existing operating system, the virtual system has exactly the same functions as the real operating system. After entering the virtual system, all operations are carried out in this new independent virtual system, which can independently install and run software, save data, has its own independent desktop, does not have any impact on the real system, and has a class of operating systems that can flexibly switch between existing systems and virtual images.

In one of the embodiments, a script is an executable file written according to a certain format using a specific descriptive language. The present application imports the prepared executable script file into the virtual machine system before the above steps, and starts to execute the above-mentioned pre-imported executable script file synchronously when the system is started. This script file is the key content of the application, which specifically includes: obtaining the correct configuration file of the network adapter, and comparing the configuration content of the current system, there will be two situations, one is that the configuration file of the network adapter does not exist, then The program written by the system according to the script will automatically create the configuration file of the corresponding network adapter and edit its content, and edit the network configuration information of the real host into it; the second is that the configuration file of the corresponding network adapter already exists, the system will The program content of the script adjusts the content of the configuration file of the network adapter, and writes the acquired network configuration information of the real host into its specific content.

In the process of using the virtual machine, when the virtual system is imported into the virtual environment and the virtual machine is started again, there will be a problem of not being able to communicate with the outside world normally. There are two main causes of this problem. One is its virtual The computer lacks the configuration files of all network adapters, which leads to the failure of normal communication; the second is that the configuration files of the network adapters exist, but the network configuration information is abnormal. The abnormal content includes inconsistent network card names, inconsistent mac addresses, and other network configurations. If the virtual system maintains normal communication, the configuration file of the network adapter needs to be added or the configuration file of the network adapter needs to be modified to the content required for normal communication, and then the communication can be performed normally. Through the above steps, the edited script file is imported into the system in advance. This script file can detect the status of the configuration file of the network adapter after the system is started and repair the configuration file of the abnormal or damaged network adapter to ensure the normal communication of the system.

Through the above steps, the configuration file of the network adapter can be automatically configured synchronously during the system startup process. After restarting the service corresponding to the network adapter, the network adapter can communicate normally without occupying the resources of the virtual system and prolonging the service life of the virtual system. The startup time effectively avoids the need for operation and maintenance personnel with poor network service foundation to spend a lot of time consulting and troubleshooting.

The script files in the embodiments of the present application will be described and illustrated below through preferred embodiments.

Step S305, configure the configuration file of the network adapter according to the network configuration information.

Step S306, restart the service corresponding to the network adapter, so that the configuration file of the network adapter takes effect.

Through the above steps, pre-editing the script file imported into the system firstly detects whether the configuration file of the network adapter exists in the computer system, and then compares the configuration file of the network adapter existing in the system with the obtained configuration file of the network adapter, and judges the two Backup configuration information for the network adapter's configuration file. When the configuration information of the two network adapter configuration files is inconsistent, first delete the configuration information in the configuration file of the network adapter in the system, and then update the service information corresponding to the correct network adapter to the existing network synchronously.
