ETHX changes or disappears after virtual machine clone replication

There are a lot of problems about virtual machine cloning after eth0 can not find or eth0 programming eth1, there are a lot of solutions but there is no real catch:

It's really simple. You just need to define the virtual machine with the following command:

Enter virtual machine:

Mv/etc/udev/rules.d/70-persistent-net.rules/etc/udev/rules.d/70-persistent-net.rules.bak

Re-define the virtual machine.

And then

Ifconfig ethx IP up

The following are other solutions but are not recommended for use.
