Let me help you.
In your case, there’s this DS920+ box, and inside the box you have VMM (is it 6 or 7?), and under the VM you are running HAOS (which is a locked-down appliance OS provided by the HA project, and you are on
HAOS 7.0), and in the HAOS you have
core 2021.12.1 (which houses the main HA codes), and
supervisor 2021.12.1 (which coordinates various aspects of HA in the background.)
Other stuff (docker, python, kernel, etc.) are underpinning things in the background, I guess for troubleshooting, and if things are working you likely could ignore those.
You don’t have to, but if you must, learn more here: Architecture | Home Assistant Developer Docs (home-assistant.io)
Down the road, your Core, Supervisor, and HA OS can be updated independently.
- Most of the HA features would come to you via
core updates. Would recommend you read the release notes to understand what would change/add/remove, and plan accordingly, before your perform each
Supervisor would update itself.
HAOS updates would bring you new drivers on new USB dongles, and new linux kernels with (kernel level) security patches.
So back to your questions:
Yes, you are running the latest version (as of today). The “Virtual Environment” thing is not about whether you run your HAOS under VMM or not, but for something else. Your install type is HAOS, as indicated on the 2nd line.
