No access of HA via IP of virtual machine

[Tsar (Christian)]

I installed ubuntu 20.04.3 LTS on my old laptop. Next I followed the instructions of a youtube video " How to Setup Home assistant on Ubuntu (supervised) from scratch as virtual machine (KVM)".

Everything seems OK, except that I can’t access my HA via my Windows laptop on “http://192.168.122.231” (Virtual Machine IP Address)
I can do it on http://192.168.1.76 (address of Ubuntu machine).

I did his instructions :
iptables -I FORWARD -o virbr0 -d 192.168.122.231 -j ACCEPT
iptables -t nat -I PREROUTING -p tcp --dport 80 -j DNAT --to 192.168.122.231:8123

What did I wrong ?

“http://192.168.122.231”

→ http://192.168.122.231:8123

The iptables lines effectively forwards port 80 from the host to port 8123 on the VM, which is the actual port on which HA is listening.

So I don’t have to change anything, everything is normal ?

Here is an alternative writeup that shows how to install and boot a Home Assistant image as a VM running on QEMU/KVM with Ubuntu:

Install Home Assistant OS with KVM on Ubuntu headless (CLI only)

Installing KVM and deploying Home Assistant OS Since the install page only describes how to use KVM via a GUI, and I am using KVM in a server setting, I thought I’d share a quick guide to how to do this from CLI only. NOTE: This is for Ubuntu Server LTS 20.04 (though I upgraded after installing this to 22.04 (do-release-upgrade, and others have reported this working on 22.04 de novo, e.g., here. I had an issue with my ConBeeII stick that I passed to HA, but no other issues, and I now use a PoE …
