VM Image Clone Problem: eth0 Renamed As eth1

After cloning a Linux image, noticed that Linux server renamed eth0 as eth1.

Further study discovered that this issue caused by previous entries in “70-persistent-net.rules”, after clean up these obsoleted lines related to previous image, it works perfect.

[root@mysql03 ~]# cp /etc/udev/rules.d/70-persistent-net.rules /root/
[root@mysql03 ~]# diff /etc/udev/rules.d/70-persistent-net.rules /root/70-persistent-net.rules
8c8,14
< SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:26:1e:69", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
