If you are using wsl because of heavy windows programs typically like games then I guarantee this won't work as well as a wsl setup. It is cool but it doesn't seem like enough for me to move away from wsl (which I'd like to do if there was true and simple 'reverse wsl')
I've used wine (typically via playonlinix in recent years) but it's hit and miss. Online games aren't always happy with it (especially with cheat detection), performance is sometimes worse (especially on older hardware) and sometimes you can make it work but only if you spend a few hours fixing things.
The best way to do it is to have a seperate GPU that you pass through fully to the Windows VM - a friend has that setup - which works perfectly but then you can't use that gpu in Linux and I don't particularly think it's worth it for me to have multiple GPUs when wsl gives me 99% of what I want with minimal setup.
Passthrough-capable video cards aren't cheap or that easy to find and actually get working properly. It's 100% a nice dream, but no single major virtualization vendor supports it for desktop purposes intentionally. It's looking like for the foreseeable future it'll continue to be an expensive and royal pain in the behind.
Of course, YMMV, I recall seeing that linus derp tech guy YouTube make it work one time. Good luck keeping it working properly in the long haul.
I feel I've already learned this the hard way, have several spare Supermicro servers to show for the result of what I consider to be a failed project.
Instead, I maintain a separate windows-only machine for such occasions. Takes up very little extra space or time.
Would love to hear from other folks who use this on the daily.
This all feels either out of date, or just incorrect.
You can use consumer cards for this. Both Nvidia and AMD consumer cards. Nvidia drivers work fine now, and don't require any workarounds (they previously "blocked" VM's with their driver, but was trivial to workaround). AMD have a few hardware quirks, but that can typically be worked around too. Though you're best going with Nvidia as it's more straightforward.
It also seems that a lot of virtualisation software supports it (libvirt/qemu, vmware esxi, proxmox, xen, probably a few others). It's typically also, set and forget. Once it's configured, you're good to go. There's not much of "keeping it working properly in the long haul". I've had my setup for about 4 years or so now. Even through software and hardware changes.
"The workaround" is to add few lines in VM's XML, which are available in pretty much every VFIO / GPU passthrough guide (in "code 43" sections). Like these ones:
And you don't have to do it for the most of AMD cards and the newest NVIDIA cards.
Unfortunately that's not beginner-friendly, I know, but that's the problem of VFIO in general - you can't really do it without being comfortable with terminal, editing configuration files etc. It would be cool to make it automatic somehow, but that would require making some tool(s) for all the preparatiary work (assigning vfio-pci driver, building united) and adding features to virt-manager (to be able to all the stuff graphically, without modifying XML).
But anyway, in your original comment you said that passthrough is not possible with consumer GPUs, which is simply not true. It's possible with pretty much every consumer card.
Intel included support on all their consumer chips until recently I believe. The mediated passthrough is different than full passthrough like you are probably thinking.
