Hey Stewart, long time no talk. Sorry about the delaying in getting back to
you on this topic, classes really kicking into high gear and life became
kind of crazy.
Copy pasted below is the dumpxml of my Win8.1 VM. I tried to add in the two
code blocks that you linked above, but I got errors when I did so. I've
bolded and marked in red where I added the first code block, the pci
definition, and then did the same for the two devices that make up my GPU.
Edit: just incase anyone's mail client doesn't like the bold / text color
change, I've also off-set the area by adding a blank line.

Adding them in was no problem in and of itself, it was saving it that
caused a problem. Virsh didn't like those two definitions. Editing the
"address type=pci" lines of both, and changing THOSE bus= definitions to
say 0x03, instead of 0x00 gives me this error:
error: XML error: Invalid PCI address 0000:03:07.0. slot must be <= 0
Editing the one above it, the "address domain=" line, and changing the bus
from 0x01 to 0x03 gives me this error:
error: XML error: The device information for 0000:00:1c.0 has no PCI
connection types listed
Any thoughts?
Half tempted to say 'screw it' and just hold off on doing a VFIO setup
until I snag an Nvidia Polaris card later this year ><
