when I cloned one of my Linux virtual machine. So the cloned machine was not able to detect the NIC and every time I tried to restart the network it was throwing this error
The MAC id details for the NIC card is stored in the below mentioned file which is automatically created every time the machine boots.
If you open this file the contents would be like this
Delete this file
rm -f /etc/udev/rules.d/70-persistent-net.rules
Reboot the machine i.e init 6
Now we can see difference in MAC id and NIC card name
Copy the new MAC id and NIC card name to your ifcfg-eth0 file
Restart the Network service using : service network restart
check for IP details using " ifconfig"
