Yeah, I mean being able to boot either into proxmox or windows. But in proxmox, I can also open that windows install as a VM.
Some details on how it should work are here (apologies for the reddit link): https://www.reddit.com/r/VFIO/comments/aejdqk/kvm_importuse_existing_windows_install_on_disk/edqtmvb/
I’m in the planning stages of a build that will be essentially this, a proxmox build that’ll include my NAS with several hard drives (running in one VM), all my docker containers (another VM) and Linux and Windows vms with passthrough that I can spin up temporarily for games.
I think I can get the Windows VM in a place where I can also restart the whole machine and boot in natively, as a fallback for games with aggressive anti cheats that won’t allow VMs, which I don’t think I’ll be playing much of anyway.
To answer your question, it really would be best to check game by game if the anti cheat allows VMs.
Framework is definitely not Linux only (laptops are Windows by default , but they offer a no-os option to install your own). They are however generally supportive of Linux, and it’s possible that they helped make the fingerprint reader firmware work well with Linux, though I have no specific information that this was the case.
