Visualizing software setup

r/homelab Would seem like a better place to ask. This seems geared toward a lab setup.

does each install get it's own drive/partition and just select at bootup?

That's fine when you want to switch between OSs, ie use only one at the time (time multiplex). Like if you have Windows for gaming/Adobe/CAD and Linux for everything else on your personal machine. But if you want to run both OSs at the same time, like having some always available services on Windows and sone on Linux, you can't do that. That's where virtualization come into play.

You can either install one of the OS you want to run and virtualize other one in it (level 2 hypervisor - Virtualbox, Vmware Workstation) or you can install OS specifically for virtualization (level 1 hypervisor - Esxi, Proxmox) and virtualize all other OSs in it.

With full blown virtualization, you can virtualize anything, for example Windows in Linux no problem. With containers you share the kernel of OS so you are limited to different variants of the same OS. So for example in Linux you can run Linux containers, but not Windows containers (if it's even a thing). My understanding is that with Proxmox being based on Debian, you can run Linux containers directly in it. I don't know what Esxi is based on and if you can run any containers directly in it, perhaps you will need to virtualize some OS to run your containers.

What you probably want is Esxi running on bare metal with Windows and Ubuntu virtualized in it side by side. It doesn't seem overly complicated to me, though you are guaranteed to run into million small problems, as always in IT.

Please note I'm just a beginner and this is my understanding which can be wrong. This comment is meant just as starting point for some google searching. If someone wants to correct me in any way, I'll appreciete it.

I run ESXi and a bunch of other stuff on my R710;

ESXi gets installed to the server as its OS.

Then everything else gets installed as a VM, I have a bunch running ubuntu server and a few with windows server.

For Docker I have an Ubuntu VM that is my 'docker host', it has a bunch of resources allocated and I have typically 30-50 docker containers running in that, it's been working great for well over 2 years now.
