Servidor Ubuntu 12.0.4 x86 não detectando adaptador de rede no virtualbox 4.3

Esta é a saída de lspic -nn

Embora obviamente minha Ethernet seja detectada na saída acima. Não está na lista ifconfig . aqui está a saída de ifconfig :

ubuntu@ubuntu-VirtualBox:~$ ifconfig

lo Link encap:Local Loopback

Mesmo que eu tente ifconfig eth0 up - recebo um erro:

eth0: ERROR while getting interface flags: No such device
