Meanwhile, various network parameters such as a network IP address, a subnet mask and the like can be changed in the script operation process, and the service corresponding to the network adapter is restarted to acquire the parameter information again. The function of restarting the service corresponding to the network adapter is realized through a certain computer instruction.

In some of these embodiments. The network configuration information of the real host at least comprises: the physical address of the network adapter, the name of the network adapter, the type of the network adapter, and the start configuration information of the service corresponding to the network adapter.
In some of these embodiments, step S202 includes: and under the condition that the communication state of the network adapter of the virtual machine is detected to be abnormal, acquiring 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, so that the network configuration information of the real host is conveniently compared with the current network configuration information in the subsequent steps, whether the network configuration information of the real host is consistent with the current network configuration information is judged, different processing is performed according to the judgment condition, the network configuration information of the virtual machine is always correct, and the normal communication of the virtual machine is ensured.
In some embodiments, a Virtual Machine (Virtual Machine) refers to a complete computer system with complete hardware system functionality, which is emulated by software and runs in a completely isolated environment. The network uses physical link to connect each isolated workstation or host to form data link, so as to achieve the purpose of resource sharing and communication. Communication is the communication and transfer of information from person to person through some medium. The network communication is realized by connecting each isolated device through a network and realizing the communication between people, between people and computers and between computers through information exchange. The virtual system has the same functions as a real operating system by generating a brand new virtual mirror image of the existing operating system, all operations are carried out in the brand new independent virtual system after the virtual system is accessed, running software can be independently installed, data can be stored, an independent desktop is owned, the real system cannot be influenced, and the virtual system has an operating system capable of flexibly switching between the existing system and the virtual mirror image.
In one embodiment, the Script (Script) is an executable file written according to a certain format using a particular descriptive language. Before the steps, the written executable script file is imported into the virtual machine system, and the pre-imported executable script file is synchronously executed when the system is started. The script file is the key content of the present application, and specifically includes: acquiring a correct configuration file of the network adapter, and comparing configuration contents of the existing system, wherein one of the two conditions is that the configuration file of the network adapter does not exist, and then the system automatically creates a corresponding configuration file of the network adapter according to a program written by a script and edits the contents of the configuration file, and network configuration information of a real host is edited into the configuration file; and secondly, if the configuration file of the corresponding network adapter exists, the system can adjust the content of the configuration file of the network adapter according to the program content of the script and write the acquired network configuration information of the real host into the specific content of the configuration file.
In the using process of the virtual machine, when the virtual system is started again after being led into a virtual environment, the problem that the virtual machine cannot normally communicate with the outside exists, and the main sources of the problem are two categories, namely that the virtual machine lacks configuration files of all network adapters, so that the virtual machine cannot normally communicate; the second is that the configuration file of the network adapter exists but the network configuration information thereof is abnormal, and the abnormal content includes the network card name inconsistency, the mac address inconsistency and other network configuration inconsistency. If the virtual system is kept in normal communication, the configuration file of the network adapter needs to be added or modified to the content of the normal communication requirement, and then normal communication can be realized. Through the steps, the edited script file is pre-imported into the system, and the script file can detect the configuration file state of the network adapter after the system is started and repair the abnormal or damaged configuration file of the network adapter, so that the normal communication of the system is ensured.
Through the steps, the configuration file of the network adapter can be automatically configured synchronously in the system starting process, normal communication can be realized after the service corresponding to the network adapter is restarted, the resources of the virtual system cannot be occupied, the starting time of the virtual system cannot be prolonged, and the problem that operation and maintenance personnel with poor network service bases need to spend a large amount of time to consult and investigate is effectively solved.

Step S305, configuring 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 becomes effective.
Through the steps, the script file which is edited and imported into the system in advance is used for detecting whether the configuration file of the network adapter exists in the computer system, and then the configuration file of the network adapter existing in the system is compared with the acquired configuration file of the network adapter to judge the configuration information of the configuration files of the two network adapters. When the configuration information of the configuration files of the two network adapters is inconsistent, the configuration information in the configuration files of the network adapters in the system is deleted, and then the service information corresponding to the correct network adapter is synchronously updated into the configuration files of the existing network adapters, so that the configuration information of the configuration files of the network adapters is kept correct.
