Troubleshoot problems with adding multiple NICs to CENTOS7 in VM11

Problem Description: After adding multiple NICs to the virtual machine CentOS, the added NIC is not working properly in VM11.

Here's how to fix it:

1. Be sure to add the network card in the shutdown state. The network card that the virtual machine adds in the run cannot be set anyway, please remove add again.

2. Check the UUID of the new network card and record it after booting

#nmcli Conn

Note that the NIC name you see here is not the same as the result of using Ifconfig or IP Add.

3. Copy the NIC configuration file and edit it:

#cd/etc/sysconfig/network-scripts/

#cp ifcfg-eno16777736 ifcfg-eno33554984

#vim ifcfg-eno33554984

Uuid=4d07269c-3ae0-49ac-a440-152803673a77

Device=

Name=

4. Restart the service to take effect.

#systemctl Restart Network
