Hi,
I was wondering if we could split group 7 any more. CPU is the 6700k. I'd
like to be able to pass through the USB controller without the ACS patch.
Thanks,

Hi again,
Thanks a lot for investigating. I've reported the issue to the manufacturer.

Hi Wei,
My system is a desktop, so it must just be a general Gigabyte BIOS bug. I
submitted a help ticket about this issue and just gave a brief explanation
and then sent Alex's explanation. Hopefully it will be escalated correctly.
Thanks,

Have you tried a BIOS install and setting x-vga=on? With my 480, there is
no UEFI image or it got corrupted somehow, so I need to pass a UEFI vbios I
downloaded to see the screen if I use UEFI. With BIOS, x-vga=on works.

I only needed core2duo when installing the anniversary update. I heard it
tries to flash CPU microcode and QEMU blocks this so the update fails, but
it doesn't try to install it for core2duo.

I couldn't get drivers installed on Q35 with my 480, and I think Alex
recommends i1440fx but he'd have to jump in to confirm.

I also need to hide the hypervisor for the "Display" tab to show up. I
assume it's a bug and not intentional. Hopefully they fix it.

Hi all,
My Ryzen stuff finally arrived, so I can help get GPU Passthrough working.
My CPU is the 1800X and my motherboard is the Asus Prime X370-Pro.
I'm on kernel 4.10.1.
The IOMMU groups are indeed bad:

As you can see, the graphics card

tomorrow.

No, it should be fine. It means the guest tried to access a CPU model
specific register, and KVM ignored it. This is usually a suggestion to fix
issues in the VM. I'm not sure how to actually disable the messages though.

Sorry, is that a SCSI controller set to virtio type, or the virtio option

I can't reproduce that issue, I tested a Fedora VM with both npt 0 and
1, of course with the same GPU performance results as windows. I've
mailed some AMD guys and KVM guys, and hopefully someone can at least
figure out what is going on. Also, Alex has reproduced this himself on
both Nvidia and AMD
Have you guys tried disabling MSRs?

Hi all,
I just wanted to send an update if you haven't heard. The cause of the
bad GPU performance with NPT enabled on AMD systems has been
identified and fixed.
The patch is located here: https://patchwork.kernel.org/patch/10027525/
I assume it will make it upstream soon. For now, you have to p

Hi guys,
When i want to do gpu-passthrough, i just unbind my GPU from radeon, and
then pass it to qemu. I don't bind it to vfio-pci or any driver and it
works fine. Is there any downside or performance loss to doing it this way?
Thanks,

e/Fast booting. Can I use a GPU like this with OVMF and
more importantly, is there any performance difference using OVMF over
SeaBios? Thanks alot,

I believe it's only needed to check if your video card bios supports UEFI
with rom-parser. You can optionally pass it to qemu, but I haven't needed
to.

Could it also be the host running out of RAM and thrashing? I've had that

Hi guys,
It seems the biggest limiting factor of my GPU Passthrough setup is the
disk. Does anyone have any tips to optimize it? Also, which is faster,
having the disk with if=virtio, or having the disk with if=none and a
virtio SCSI controller. The raw image is 250GB on a 500GB ext4 hard drive,

Hi guys,
I'm using libvirt and virt-manager for my GPU passthrough setup, with
no-root. For the life of me, I can't figure out how to get pulseaudio
working. Even though it is running as user, libvirt is trying to look in
/root for pulse config files. The VM shows I have an audio device
connected,
I managed to solve this. You run pulse as the user, with anonymous auth and
a unix socket at /tmp/pulse. Then, set PULSE_SERVER=unix:/tmp/pulse in the
envvars for the domain xml. Works from there.

Hi Jiri,
I just wanted to add that a similar issue is effecting me. With qemu 2.6, I
get a black screen after the seabios screen. Downgrading to 2.5.1 fixes it
for me. I tried 2.6 with the pc-i440fx-2.5 machine type, but that didn't
work either.
If anyone has any ideas, let us know.
Thanks

Hi guys,
I recently purchased the RX 480, but I can't unbind it in the same way as I
