Thought I'd mention that in my situation I have to make some adjustments to get EFI boot to work. I use two GPUs, one Nvidia, and the XTX. I had to use the dumped bios for the XTX I had to change video=efifb:off to video=efifb:off,vesafb:off,vesa:off I had to disable resizable bar in the bios (but kept "above 4g decoding") The good news is that after getting EFI boot to work I no longer had to restart the host every time I needed to reboot the XTX VM, the bad news is resizable bar does not seem to work for the XTX VM yet. Cheers!

I somewhat agree, but Nvidia's left reality with their pricing, hence my move back to AMD. 4070 ti is a good card!

I've tried everything in this thread but can't seem to get my XTX passthrough to post. It and the VNC says "...has not initialized the display (yet)". When I run it with just the VNC it boots, when I passthrough my secondary Nvidia 3080 it works. Tried disabling resize bar and setting the XTX as the non primary gpu in the bios, and nothing happens. I've run out of ideas. Edit1: was finally able to get it to post. I do have to reboot the host each time I want to reboot the VM right now. Now my problem is with the driver install, it gets to 79% then just sits there and does nothing. Edit2: Finally seeing some results. I am passing a SATA drive to the VM so I figured maybe I should just install the drivers in bare-metal and possibly bypass whatever problem I had with that. I got it to work! I did pick Q35-7.1 instead of i440fx-7.1 when I finally got it working, maybe that was my issue with installing drivers? Is Q35 good or bad? Now that it's seemingly working i'll try and get it to work in EFI boot. Big relief.
