I would want to share how you can change the Network Interfaces Name in Centos 7 machines.
First you need to edit file as below :
You may add "net.ifnames=0 in GRUB_CMDLINE_LINUX" variable as below.
GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet net.ifnames=0"
then rebuild the grub to apply the name on boot.
grub2-mkconfig -o /boot/grub2/grub.cfg
Next, you may now rename the network interface that suits your preferences
cd /etc/sysconfig/network-scripts; mv ifcfg-ens32 ifcfg-eth0
When editing the network-interface, remember to also change the value of DEVICE and NAME, then reboot the server.
After reboot, use command "ifconfig" to verify whether the Network Interface name are changed.
