Fixing missing network interface card in cloned Linux VM

By default, when you clone a Linux VM, VMware creates a new MAC address that you can find under VM Settings. However the cloned VM itself contains MAC address of the original VM in its network configuration file. Due to this conflict, you may experience missing network interface card while you boot your cloned Linux VM.

Here is the fix to bring up the network interface :

Step 1: Get MAC address of VM (from VM Settings) assigned by VMware

Step 2: Identify interface name in VM

Use any of these commands ip aifconfig, nmtui or nmcli device show to find out interface name, usually the name starts with eth e.g. eth99

Step 3: Identify interface configuration file

Navigate to following path and identify the configuration file eth99 (as per our example, in your case, it may be different)

# cd /etc/sysconfig/network-scripts
# ls -l if*

Step 4: Update interface configuration file with correct MAC address noted in Step 1

# vi /etc/sysconfig/network-scripts/ifcfg-ens99

Step 5: Remove MAC address associated at startup

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

Step 6: Type “service network restart” or “reboot” to bring up the network interface
