LOL…not even 10 minutes ago I had a similar problem. Is your second NIC actually connect to a ethernet line, or if virtual is it set to “CONNECTED” in the nic config for the VM?
Yeah the virtual nic is connected. Just for testing I ran the installer on a physical machine with 2 connected nics, and it does the same thing. It will show the second NIC in the console, but wont show it under network in system admin.
