I've set up a virtual server on Hyper-V running latest Ubuntu 12.04.
The server has two identical NICs set up as legacy devices in Hyper-V, the first connected to the physical network of the Hyper V, the second connected to a private Virtual LAN on the Hyper-V. The LANs are assigned different subnets.
I can not get the latter to work, even though I know the private LAN is working, with several (windows) VMs connected. I've tried static/dhcp setup, reinstalling with the NICs in different order eth0/eth1 etc, but I can't get it to work.
