GPU passthrough block booting process - RX 470

[oursondechine]

I'm a new trial user trying to setup a gaming VM on my unraid server. I got everything working throught VNC thanks to spaceinvader one's videos on YT. But even while following his tutorials about GPU passthrough i can't have windows booting.

 

I tried:

* with and without a primary card as VNC

* with and without a rom bios file from the internet

* with and without a rom bios file that I dumped using is explanation in https://www.youtube.com/watch?v=mM7ntkiUoPk&t=324s

* editing the xml to have the video and souncard as a  PCIE multi function device as explain in https://www.youtube.com/watch?v=QlTVANDndpM

 

Every time I boot with a GPU other than VNC, windows won't boot, it get stucked on the black screen with a small loader; the loader spin until it stopped and nothing happens until I force stop the VM. After that if i reboot windows with VNC activated only, it try to repair itself with no success; but if i reboot again with same settings it's working.

 

I have no error in the UNRAID VM logs.

 

It's been 2 days and I'm really out of solutions; what else can i try ?

 

EDIT: I have a persona rule that state that every time i have an IT probleme, i try for few days then ask for help; and that rule also state that when you ask for help, by providing all the details, you'll stumble on a piece of informations you missed. This solved me a lot of programing error and today I found that I missed the 'Q35' reference in the post bellow. So i fixed it 30 seconds after i made this post. Hope it can help someone as dumbass as me and found this thread on google.
