Due to the need to add the network card to the virtual machine (oracle linux 7.1) and set the IP operation, execute the ifconfig command after the increase of the network card, you can see the increased network card information, but no network card configuration file is generated

You can see that the network card configuration file ifcfg-ens34 is not generated, and the network card ens160 added before when creating the virtual machine has the corresponding configuration file ifcfg-ens160. Nmtui is used to set up the network in oracle linux 7.1. nmtui belongs to curses-based text user interface (text user interface), similar to the previous setup tools of Linux7.

[root@jytest1 ~] # nmtui

After setting up using nmtui, you can see the configuration file ifcfg-ens34 that generated the network card ens34.
