Sometime you may need to change the Network Interface Name on your system. I faced issue while I was cloning a node to prepare a new node for RAC Environments on Oracle Linux 6.5.
When you clone a VM, you need to reassign the Network device means it will assign new UUID for the device and it will create new Network Interface at OS level. But For RAC, You need to set same name of Network Interface for all nodes. I got below error while was trying install GI (Grid Infrastructure) with different Network Interface Name.
Issues:
Network interface bonding status of private interconnect network interfaces - Checks if the network bonding feature, if used for private interconnect network interfaces, is configured using correct bonding mode Operation Failed on Nodes: [ocmdrnode1, ocmdrnode2] Verification result of failed node: ocmdrnode1 Details: - PRVG-1512 : Failed to retrieve current selection of public and private network classifications - Cause: Could not retrieve the list of public and private network classifications selected in current configuration. - Action: Ensure that the configuration of public and private network classifications is done correctly during the installation process.

I again tried to restart my network and it started this time, however, the ifconfig was still showing old one, But the configuration file eth0 was picked up.

Renaming my network interface to eth0:

After changed the /etc/udev/rules.d/70-persistent-net.rules file:
Note:::Make Sure you are renaming correct one with mapping ATTR{address} attributes.

You need to reboot the OS / VM to see the impact on -> ifconfig command output.
After rebooted OS/System:
