Reset eth0 to move ubuntu server 14.04

New Ubuntu Server 14.04 instance for installation on a dedicated server. Everything required is setup as a vbox guest then I add the drive to the allocated server. When I was using 12.04, my last step would be to rm -f /etc/udev/rules.d/70-persistent-net.rules to reset eth0.

Ubuntu 14.04 does not use 70-persistent-net.rules anymore. Does anyone know how to reset eth0 for auto config on boot using the new network adapter?

Launchpad Bug #1312785: ethernet Interface naming has changed

Solution 1:

Starting with v197 systemd/udev will automatically assign predictable, stable network interface names for all local Ethernet, WLAN and WWAN interfaces. This is a departure from the traditional interface naming scheme ("eth0", "eth1", "wlan0", ...), but should fix real problems.

See if this helps; here and over there some more background on the topic, if you're interested.
