I didn't modify the XEN kernel. It's a debian squeeze installation. It comes
with precompiled XEN kernel 4.0.1. I got a integrated GPU in my intel clarkdale
(i5-650) CPU. I read that the intel integrated GPUs would work with XEN.
Couldn't find anything in the wiki or on the list, so i thought it would work
out of the box with Intel GPUs.
Here comes the complete "xm dmesg" with iommu=verbose:
