Then I created a Docker image with Linux, Gnome, and novnc so I can spin one up instantly with little resource overhead and control it from any web browser.
Sort of, Proxmox does use noVNC I think, but it’s a lot of overhead. This is just a docker command. I’ve finally put a page up for it: https://nowsci.com/webbian/
Correct me I’d I’m wrong, but with docker you’re limited to the filesyatems and the image of the OS you’re installing. If you need to experiment with the pre-OS boot events, can that even be accomplished with docker? E.g., trying out different GRUB settings, setting up LUKS with dropbear etc. I think those things require a VM.
Yeah, you are correct. Docker shares the kernel with the host operating system, it doesn’t use hardware virtualization. That’s why it’s so fast and simple, but it also means it’s not a traditional VM and thus comes with some limitations.
None, I use Docker for Linux, and Proton (Heroic) for Windows.
But if I had to pick a virtual machine: libvirt with virt-manager as a frontend, which uses KVM for virtualization.
From my other comment:
Maybe I should release my Dockerfile.
i’m listening.
Finally got around to it: https://nowsci.com/webbian/
i will be trying that one out for sure. this looks awesome for a headless desktop.
I might actually be interested. It’s like a lightweight alternative to Proxmox?

dockercommand. I’ve finally put a page up for it: https://nowsci.com/webbian/I didn’t understand that you ran it without hardware virtualization. This is really convenient, thanks a lot for making it!
I’m just learning about Docker and Containerfiles, so I wouldn’t be opposed to a real world example…
And the example finally exists: https://nowsci.com/webbian/
Neat! Gonna look over that!
Its fair bcs vmware workstation does not support gpu passthrough libvirt with virt-manager is the only way
OpenShift Virtualization

Can virt-manager boot windows boxes?
Absolutely, it’s also made way easier with quickemu, allows you to spin up a properly configured Windows VM with pretty much no effort

Yeah, though there’s some commandline shenanigans to get a tpm shim set up if you want it for windows 11
I am planning for XP.
