When cloning a Linux VMWare machine, you will get problems with your cloned VM not recognizing your network card. This is because VMWare automatically creates a new MAC-address on your cloned machine (to prevent duplicate MAC issues). Your Linux OS however doesn’t know it’s been cloned, and will still have the same MAC address. To resolve the issue that your Linux clone doesn’t recognize it’s network card, remove the following file:

# rm /etc/udev/rules.d/70-persistent-net.rules

The above file holds the configuration of the network cards, with the wrong MAC config. When deleting this file and rebooting, the file will be created automatically with the current right configuration.

Reboot after deleting the above file, and you network card(s) will be recognized again!
