From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'm considering to switch to Proxmox for my main PC, run a Windows VM on top and passthrough the GPU to play games. However, I heard anti-cheates aren't that friendly to VMs. Had anyone tried this? Thanks.

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.

How can you boot natively to a proxmox VM? I'm guessing you'd have to keep a whole separate physical drive and pass through the whole drive to the windows VM or boot to that drive natively?

Maybe they mean they will dual boot between windows and a hypervisor? I've never considered if that's a possibility.

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/

Yup, that's pretty much it! I haven't figured out the specifics of setting it up beyond the fact that it's possible. If it proves too complicated, I suppose it's not too much harder to just maintain separate drives for Windows VMs and dual booting, since I won't ever use it for anything other than games.
