The original system (from where I took the VM) was 12.04 w/o network manager and unfortunately I have not tested it with network-manager installed.

After adding the ip address and routes to the interface my machine (naturally) started to be able to communicate with the world. I feel this is a regression since there was no additional configuration involved with 12.04 to get this up and running.
