It's not a stable solution, and there are two problems with this kind of things. The first is that it's pure, unsubstantiated, guesswork. You'll spend countless hours changing obscure undocumented parameters hoping that things will work. I tried, and it's not a fun thing to do, because you don't learn anything substantial. Second, this type of operations have a sky-high level of brag factor. People will tell on their blogs/posts that they succeeded in "making XXX work and that it's stable", but they don't tell you that their computer explodes (so to speak) two minutes after they start XXX. Again, I know because I've worked on similar things, and the patterns are the same. You may be lucky, but if you aren't, it's a lot of time wasted (it always looks like the "final solution" is behind the corner!).

The guys from LinusTechTips have used Unraid (a paid KVM+BTRFS based NAS+VM appliance) to do this with a 7 or 8 GPU machine. See 7 gamers one PC on YouTube. It seemed to be simple to set up, once you have configured the BIOS.

Yeah, it can be a bit guessworky, but that's only because it's bleeding edge stuff. The corners are being sanded down and things are getting better rapidly. I've been happy with the amount of work that I've put into my setup versus the results. And my setup is definitely not one that causes my computer to explode. In fact, I've never had my host machine fail. The VM only bugged out once. This is after long sessions of CS:GO, Overwatch, Game of Thrones, StarCraft 2, etc.

I was pretty apprehensive about the concept, but hopeful enough to get a new mobo/CPU just to give it a shot. It does definitely seem to good to be true. I went for it, and it actually ended being significantly easier and better performing than I expected. I did have to take a few days and learn a bit about qemu, but I'd expect that much. I will say that older motherboard (perhaps some new ones too) might not have firmware that fully support what's being done here. It's hard to say which, but you can see what people have had success with if you search around (Asus z170a works for me). This is a little light on details but is a good resource for the steps involved: https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVM...
