Problem with network configuration

[warinthestars]

So I installed the latest version on a Lenovo Thinkcentre m71e, and while booting, my network switch is showing activity, however when Proxmox loads, the activity light goes out and it's like the interface has been shut off. I have found no other help searching online.

When I do netstat -i it shows eth0 and it's MAC address but nothing attached to it.

What do I need to do to get it to work?

Hi,
please send the output of

cat /etc/network/interfaces

and

ls -l /sys/class/net/

Sorry about the formating, but here is the output

Code: ls -l /sys/class/net/
