Everything about it is fickle. Motherboards and USB controllers present themselves different from maker to maker, and SKU to SKU. Any change in your hardware -- including plugging in something like a USB device -- sets off a chain of fighting the host OS and virtual machines for who gets to use that device, who gets to see that device at all, and the drivers needed for the hardware.

No one is making user software with VFIO in mind. You will get random apps that do not launch in your virtual machine despite everything else running smoothly.

You're screwing with it near daily, certainly weekly. Need to update a driver, such as your GPU on the virtual machine? May god have mercy on your soul that everything works after, or that you can even get the host OS to deal with the GPU correctly at all.

I can sort of tell you haven't really read up on one of these setups because you seem incredulous that running Windows inside Linux is somehow finicky.

It's not ready for prime time, period.

Thanks for the detailed response.

I personally don't mind the semi-daily tinkering with my config, but if even plugging in a USB might break things then it does sound petty unreliable.

Ouf. You have a great imagination, but I think you'd do better to put it into writing fiction or something like that. I asked you to provide details on your comment, didn't make any statements on whether it is indeed finicky or not, I run many Windows vms on linux but never with VFIO. Your snide remarks reflect nothing more than your lack of self-esteem.

Apart from some initial issues it’s mostly been set it and forget it for me? I’ve been running a VFIO setup since 2017.

GPU driver updates haven’t broken anything in years. Nvidia actually made their drivers more passthrough friendly not too long ago (No longer need to spoof the vendor ID).

I have not had any compatibility issues with software either. I know there are some multiplayer games that specifically check if you are running in a VM and refuse to run. It’s a handful of games though and I don’t play those.
