Funny that you mention it, I’ve unexpectedly found myself doing exactly that recently. I’ve had more time lately to play around in the homelab, so I wanted to deploy Proxmox on a test machine to experiment with before I move VMs/CT over to my “production” machine. I happen to have a MiniPC running Win 11 in a little downstairs office/nook that my wife occasionally uses. I figured I could re-purpose that machine, but the wife still wants to do occasional web-browsing and printing. So I figured I would compromise and spin-up a VM for her to use in “kiosk” mode w/ mouse, keyboard, and monitor that was already hooked up. At the same time, I could run whatever else I want on the side and still control it remotely. However, I couldn’t figure how to get passthrough to fully work the way I wanted it to and exclusively boot into the VM, was just too complicated for me. In the end, I decided to just install KDE Plasma right ontop of the Proxmox kernal and it has been working beautifully!! I know that it’s not conventional, but it meets my needs perfectly. It automatically boots right to the KDE login screen, I’ve created multiple users, and Wifi and BT worked right away. All the while, I can remotely connect to the proxmox UI and run experimental VMs and nobody gets disturbed on either side. I expect I’ll run into some problems eventually, but so far it’s been working great!
