If the newly added network card equipment exists, the newly added network card equipment can be matched with the corresponding network card equipment in the Linux system through acquiring the information of the newly added network card, or the newly added network card equipment appointed by a user can be directly used as the current newly added network card equipment. The process of determining the configuration thread corresponding to the newly added network card device may directly call the configured configuration thread, or may be created after receiving the network card configuration request, which is not limited herein.
In general, there may be more than one Linux operating system type of a target virtual machine, and network card configuration processes of virtual machines under different types of Linux operating systems may be different, so as to increase an application range and set corresponding configuration threads for different operating system types to adapt to network card configuration processes of virtual machines under different types. Specifically, the process of determining the newly added network card device and the corresponding configuration thread may specifically include the following steps:
s121, reading system type information of an operating system to which the target virtual machine belongs;
s122, matching a network card configuration thread corresponding to the system type information as a target thread;

S123 may be executed before or after any step before s124, and the execution order of s123 is not limited in this embodiment, and may be set according to actual needs. The specific implementation of s122 is not limited, and a thread for network card configuration (which may be used for configuration of a multi-operating system, that is, a general configuration thread) may be created, where the thread first reads the type of the Linux operating system, and then configures the Linux operating system according to the network card configuration mode of the operating system type; the configuration threads under each type may also be configured in advance, and after the current operating system type is determined, the corresponding configuration thread is called to perform network card configuration.
And step s130, calling a configuration thread to configure the newly-added network card device in the target virtual machine.
The configuration thread is obtained according to the configuration flow setting of the newly added network card and can be used for automatically configuring the newly added network card device, in this embodiment, the configuration thread capable of achieving automatic network card configuration is called to set the determined newly added network card device, so that automatic configuration of the newly added network card during the operation of the Linux virtual machine can be achieved, the complexity of network card configuration is reduced, and the network card configuration efficiency is improved.

s142, organizing the newly added IP information in a preset format to generate network card configuration information in a specified format;
accordingly, s150 may specifically include: and adding the network card configuration information into the network card configuration update file and storing the network card configuration information.

The network card configuration updating program can read the file at regular time and then make correct IP configuration according to the environment of the Linux operating system. The configuration format is, for example:
Dev:eth0 IP:192.168.1.2MASK:255.255.255.0GATEWAY:192.168.1.254
Dev:eth0 IP:192.168.2.2MASK:255.255.255.0GATEWAY:192.168.2.254
the IP configuration of the network card can be updated, development and expansion can be performed according to specific requirements of software, and network card configuration setting other than IP setting can be performed according to actual requirements without limitation.
Based on the IP configuration, before s141, the following steps may be further performed:
s160, when a plurality of newly added IP information is determined to be obtained within a preset time interval, determining the obtaining time of each newly added IP information;
accordingly, s141 specifically includes: and determining the newly added IP information with the latest acquisition time.
