Looks like it is only seeing 1 network interface.
Could you post the output of
We can see if it is plumbing up a virtual interface off of a single NIC card, and then maybe we can see if you are having a driver issue for the second NIC card not to load, or perhaps there is a bad NIC suspect, so could you also post the output of:
sudo lspci -v|grep Ethernet
I had this happen to me both because of a driver and because I had a bad NIC card. On two separate installations.
See if we can get it sorted out.
