I have a working configuration with an RX480, Windows 10 guest and Linux x64 host, but with a Sandy Bridge i5. Can you give more information? Host kernel version, chipset, iommu groups, qemu/libvirt configuration... Have you ever managed to get it working with a different graphics card or guest OS?

Oops. Forgot, that it was a qemu patch against non-released qemu-2.9. Sometimes it is helpful to have a developer correcting the bad memory segments of mailing list subscribers. ;) So that one might actually also help. Is the Kabylake kernel fix irrelevant in this case? Thanks, Manuel > On Thu, Feb

Ok, thanks for 2. I just found it funny, that I’ve seen this on bare-metal too. 1: Yeah, I was unsure about that. I considered 2 guest systems as a possibility, but the description was unclear. So yes, you most likely need the patch for Kabylake, which will be in 4.11, so it is not available in any

Hi, in theory kernel 4.4 does not support vfio-igd yet, but since it works for Broadwell/Skylake, Ubuntu seems to have backported the patches. There was a fix released for Kabylake, that will be introduced in kernel v4.11. Interesting by the way, that it works to some extent. I’ve seen that scree
