Re: [vfio-users] Boot using second GPU?

That's something you should fix in the BIOS. The boot GPU is special because the motherboard has to use it to display things such as POST messages and such, so it's already "tainted" by the time the kernel gets a hold of it. I had to put my guest GPU on my motherboard's second PCI slot because

Re: [vfio-users] How do i get rid of the emulated gpu?

You're probably talking about the QXL video adapter. Virt-manager won't let you remove it if your guest needs anything that relies on it (I'm guessing libvirt stops it from doing that, but neither of them is especially verbose). You can't remove it until you've also removed the Spice virtual di

Have you checked what "dmesg -w" shows while you start up a VM with your GPU passed to it? I was having similar issues before, and it turned out that I had to get libvirt to append the GPU to the VM after it was done booting because of some invalid rom issues. Could be worth a shot. On 2016-01

Ok, try to remove your passthrough from your guest configuration (either using virsh of virt manager). That is : remove the actual gpu (PCI:1:0.0) but keep the associated sound card (PCI:1:0.1) in there so virsh knows it needs to bind with this VFIO group. From there, create a file (let's say ./
