No network card when moving a vmware ubuntu server

February 4, 2012 by The Man

This is a common problem also when a Vmware machine is moved to another server.

It is beacause the new card has a different MAC address.

Unlike Ubuntu Desktop, the server version is desgned NOT to make an assumption of how the card is configured – just in case it gets it wrong & places vulnerable data outside a firewall on the Internet.

You can enable the card easliy by deleting a file:

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

Then reboot.

This file is recreated with the new card MAC address upon reboot.

Then check your settings.
