Looked into it before. Was a bit too complicated for me.

Actually I don’t really want guest OSs to think about. Solid point.

Can Vagrant be used for production? Or is there another orchestrator for it for clients or me to quickly provision stuff?

Dude, that’s super cool!

Can terraform (or OpenTofu) be used to create local VMs as well? I always thought it was just for popular cloud infrastructure like Digital Ocean or Google Cloud.

Qemu would be awesome. But I’m looking for more of an orchestrator. I’m on Arch Linux. Incus looks awesome! https://linuxcontainers.org/incus/

Better security and separation of my personal files.
