I am facing the same issue, did you manage to solve it?

bishoyroufael commented 3 years ago

Hey @rosenpin . Unfortunately, this won't work easily if your laptop is MUXless laptop. meaning that your NVIDIA Gpu isn't connected to the HDMI port directly. check in your lspci, if your GPU is showing as 3D controller then your laptop is MUXless. you can have a look at the current status of MUXless laptops with vfio here : https://www.reddit.com/r/VFIO/comments/8gv60l/current_state_of_optimus_muxless_laptop_gpu/

I'm not using a Laptop, I'm using a PC with my display connected to the integrated graphics card, I'm trying to set up passthrough using my GTX970

bishoyroufael commented 3 years ago

Did you connect your hdmi port from your GTX to your monitor?

rosenpin commented 3 years ago

My monitor is connected to my integrated graphics card, so the GPU will be available for passthrough

Isn't that what I should be doing?

arthefaz commented 3 years ago

any chance that the display is set to anything other than qxl-vga? Screenshot_20210307_072945

same here :(

How many monitors do you have? If you passthrough your GPU to your MacOS guest, the video will be directed to the GPU and you need another monitor to connect to the GPU.

@b15h0y this is because passthrough mode display image to real gpu, host could not show the content of passthrough GPU. You could check it if you connect a monitor to your passthrough gpu
