I am trying to pass through my new 6800xt GPU to my VM. I have a secondary card that I use to run XCPNG- a GT 710. My mobo is a MSI B550m if it makes a difference.

I have followed the official tutorial and am currently stuck on step 2.

I am able to block my 6800xt Card with the command:

/opt/xensource/libexec/xen-cmdline --set-dom0 "xen-pciback.hide=(0000:04:00.0)(0000:04:00.1)"

The PCI bus is very similar to the tutorial, I did not just copy the PCI bus. I determined this bus by seating my GT710 GPU in the slot that I want to blacklist. The 04:00.0 bus only appears if a GPU is seated in it.

After the bus is blacklisted I reboot the system. The system always boots with the 6800xt, no matter what GPU slot it is in.

The only GPU that XNC-PG Center is saying I can forward is the GT710.

If anybody has solved something similar I would appreciate If you could tell me what I'm doing wrong...
