Zeze21, I also understand the frustration. I have a hunch about this bug in that it is related to the VM template. In my Unraid box I have 3x Nvidia GT1030 GPUs.
My problem:
I cannot run 3x VMs using the Debian or Linux templates concurrently. I can only run two instances of Debian, then the third one has a blank screen. I've even tried passing through the vbios, but it had no impact. I have to pause and force quit that VM.
However, if I set the third VM to Windows 10, it launches fine.
In other words, I am able to run Debian+Debian+Windows10, but I cannot run Debian+Debian+Debian.
To prove this, I set out to simply get to the UEFI BIOS screen.
I set up a basic Windows 10 template with these options:
i440fx-7.1
OVMF
10 MB Vdisk
Default VirtIO (doesn't matter, we're just trying to get to QEMU/UEFI)
GPU passed through
USB Controller passed through
I was then able to get to get video output from the UEFI bios with this template.
However, when I try the same thing with a Debian template, I get a blank screen.
Zeze21, I realize that your time is valuable, but why not try the same thing (or experiment yourself with various minimal VM templates) to see if you can get to UEFI using Windows 10 templates? If you can confirm my hunch, then it might help the developers fix this bug faster.
