How to Change NIC Device Name Back to eth0 on Enterprise Linux 7

After installing CentOS 7.1 release 1503 in a virtual machine, I found the conventional NIC name has been changed as eno16777736, not eth0 anymore. But this could be changed back by following steps:

1. Make sure MAC address of eno16777736
[root@test ~]# ifconfig eno16777736
...
        ether 00:0c:29:4e:c6:92  txqueuelen 1000  (Ethernet)
...

2. Add or change udev persistent rules
[root@test ~]# vi /etc/udev/rules.d/70-persistent-ipoib.rules
...
ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{type}=="32", ATTR{address}=="00:0c:29:4e:c6:92", NAME="eth0"
Or on this file:
[root@test ~]# vi /etc/udev/rules.d/70-persistent-net.rules
Both files can result in the same effects.


3. Rename the NIC file as ifcfg-eth0
[root@test ~]# mv /etc/sysconfig/network-scripts/ifcfg-eno16777736 /etc/sysconfig/network-scripts/ifcfg-eth0

4. Change device name into eth0
[root@test ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
...
NAME=eth0
DEVICE=eth0
...

5. Bounce the server
[root@test ~]# init 6

6. Check the ifconfig
[root@test ~]# ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
...

All done!
