1. VMWare -After cloning eth0 cannot be found

1.1. Answer

This issue happens because of mac address conflict in VM image and in configurations. Due to this, OS changed the eth0 to eth1.

Two solution:

1.      When VMWare player is used, you get two options- 1. “I moved it” 2. “I copied it”  while opening the VM image. Chose “I moved it”. This means, you are not changing the mac address. So, there is no conflict and everything works well.

Alternative solution:

If you indeed need to use “I copied it” (when you want to run the old and copied machines simultaneously for whatever reason). Do this:

1.      sudo rm etc/udev/rules.d/70-persistent-net.rules
2.      Comment mac address (HWADDR)@  /etc/sysconfig/network-scripts/ifcfg-eth0
3.      Reboot

2. VMWare - Unable to connect to the Engine, the IP Address isn't retrieved

2.1. Answer

It should occurs when you restart the VMWare or assign a different Mac Address when you reboot.

In fact, the computer keeps the IP Address associated to this Mac address.

If the Mac Address changes, then please edit the file located here:

sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0

The line HWADDR should content the mac address of this computer.
