Hi, I’ve been trying to pass-through one of my NVIDIA GPU’s to Windows, however the display “blackouts” very often due to the nvlddmkm driver stopping to respond and recovering as mentioned in the Windows logs. So far I’ve tried setting the PCI pass-through to permissive as mentioned in the troubleshooting guide but that didn’t change the behavior, I’ve also tried downgrading the NVIDIA drivers on Windows, I’ve also done an UEFI installation, the Windows versions I tried were 7, 10 and 11.
Here’s /var/log/xen/console/guest-gpu_windows-11-dm.log:

I’ve passed-trough the same GPU to multiple Linux distro’s and I didn’t come across any issues.
