I Konrad, first, thanks for your input and your time, it is much appreciated. I understand that those changes are torward the linux kernel, which is used by xen compilation. I applied the changes and i'm rebuilding Qubes with xen 4.6.1 based on a kernel-4.1.24. Will test the build in the next

Sorry for the precedent post that was written a bit too fast. Libreboot was flashed when I wrote it, which is the equivalent of a having vt-d deactivated (iommu=0). Thanks to a user that read this post and wrote to me personally so I could do my mea culpa. Sorry for the precedent misleading post.

The problem wasn't with xen iommu support but kms/drm and i915 driver. Passing to the kernel i915.preliminary_hw_support=1 fixes it all :) Thanks Le mer. 6 janv. 2016 à 22:11, Thierry Laurion a écrit : > Nope. That commit is present in 4.6 and results in x200 being

Nope. That commit is present in 4.6 and results in x200 being able to boot xen. Not having that option makes xen hang at boot. If present, it works until other vm access pass-through devices, which I'm not able to troubleshoot even through amt SOL. See here for debug logs:
