[vfio-users] Problem with installing Windows drivers for Quadro M2000M(GM107GLM)

[Eddie Yen]

I'm not try on it but I guess not,

Even GTV-g using native driver on Windows guest, but it doesn't mean it can
also mount Optimus GPU together.
For the way you can try is GVT-g + VFIO, that means using shared Intel GPU
and mount NVIDIA GPU into one VM.
But I never try it, it may have some compatible issue.
