eth0 missing in Ubuntu LTS

After fresh installation Ubuntu LTS, the machine suppose to grab IP Address from DHCP (in my situation).
Unfortunately the machine only show lo (loopback) interface.

When we check ifconfig -a | grep eth, it shows eth0 which means that the interface is exist.

The problem is the machine could not determine eth0 either static or Dynamic IP Address.

In my case, I wanted the machine to grab the IP Address from DHCP, in that case;

I just key-in sudo dhclient eth0 

Then, try ping to www.google.com (for example). Good Luck
