<p>From what I recall, Linux cares about the underlying PCI
configuration whereas Windows does not. Have you tried attaching
your GPU to an ioh3420 root port? That should rectify the problem.<br>

<div>I would recommend trying the whole thing on Arch Linux
using this <a moz-do-not-send="true"

<div>Although I don't have experience with OVMF, using seabios
happily with RX480.</div>

<br>
For quite some time I have been able to do a pass-through
of R9 290 to<br>
Windows VMs using KVM. The problem is that I tried to use
Linux and it<br>
does not work. Tried Fedora and Ubuntu and both did not
work. Funny<br>
thing is that Ubuntu startup/shutdown screens show on the
secondary<br>
monitor but not the system itself.<br>
<br>
I tried using i440FX and Q35, same results. Used the same
configuration<br>
I use for my working Windows VMs.<br>
<br>
I had opened a but few months ago but no answer so far.<br>

I just wonder if someone was able to bypass this problem
or has some<br>
suggestion.<br>
<br>
Thank you,<br>
