Fresh install not finding network interface

Installation
1

I’m trying to install HAOS on a SuperMicro-based machine. Ubunto runs fine, and can download the HAOS restore image using Firefox without any issues. I use “disks” to restore the image to the primary HDD on the machine, and then reboot.

I get this:

Welcome to the Home Assistant command line. 

Waiting for Supervisor to startup... 
System information 

  OS Version:               Home Assistant OS 15.2 
  Home Assistant Core:      landingpage 

  Home Assistant URL:       http://homeassistant.local:8123 
  Observer URL:             http://homeassistant.local:4357

Networking wise, the machine is ethernet wired to a switch, which is ethernet wired to a router. The machine has a Baseboard Management Controller (BMC) which works fine, and is how i can work with the console.
I don’t see the machine from the admin page on my router (other than the BMC), and I don’t get a connection into homeassistant.local:8123, so I tried

ha > network info 
docker: 
  address: 172.30.32.0/23 
  dns: 172.30.32.3 
  gateway: 172.30.32.1 
  interface: hassio 
host_internet: false 
interfaces: [] 
supervisor_internet: false

I suspect that the issue is to do with the network interfaces on the machine. Does HAOS expect there to be an eth0? From Ubuntu :

ubuntu@ubuntu:~$

So the machine has 4 physical ethernet ports, eno1 to eno4

Also, with HAOS booted I get

Can you help? Am I barking up the wrong tree entirely? (quite possible)
Thanks for any help you can give.

I am having a very similar issue.
Bare metal install, when booting into an Ubuntu flash drive, I see my physical interface (ens5f5) and receive a proper internet connection through it.
When booting into HAOS, it doesn’t see that interface at all. And my nmcli dev show looks similar (with no physical interface).

3

My problem is that I don’t know what I should expect to see from nmcli. Should I be able to see physical network interfaces?

So that I can try to follow this up further, can anybody who has a working HAOS share the output of “nmcli dev show”?
To get there, I start at the console :

Welcome to the Home Assistant command line. 

Waiting for Supervisor to startup... 
System information 

  OS Version:               Home Assistant OS 15.2

  Observer URL:             http://homeassistant.local:4357
ha >

at this point, I can press ctrl-alt-F2 on the console to bring this up:


Welcome to Home Assistant
homeassistant login:

I type in “root” (no quotes) and there is no password
it responds with:

Welcome to Home Assistant OS.

Use `ha` to access the Home Assistant CLI.

Now I type in “nmcli dev show” (no quotes)
