How to fix cloned virtual machine network interface (Linux host)

Remove the kernel’s networking interface rules file so that it can be regenerated
# rm -f /etc/udev/rules.d/70-persistent-net.rules

Restart the VM
# reboot

UPDATE your interface configuration file
# vim /etc/sysconfig/networking/devices/ifcfg-eth0

Remove the MACADDR entry or update it to the new MACADDR for the interface (listed in this file: /etc/udev/rules.d/70-persistent-net.rules).

Remove the UUID entry

Save and exit the file

Restart the networking service
# service network restart
