Hello,
I’m trying to work through yet another Code 43 error. I’ve followed Alex
Williamson’s VFIO blog to try to pass through my GPU to a guest. My GPU is an
NVIDIA GTX 770 and the guest is Windows 10. My host is Fedora 25 and I’m using
the vfio-pci driver. I’ve manually installed the latest NVIDIA driver (378.92)
from their website.
Here is my .xml for the virtual machine:

Could the last line of that log be leading to anything causing this code 43? Is
there anything else I could be missing?
Thanks in advance.
