Sure. My IGD is also Intel HD Graphics 4600. :-)

1. hypervisor version: c/s 26666 in xen-unstable.hg tree (5 months ago)
  traditional qemu commit: 5ae58eaa967495fce99b727422054c58750d252b
  Dom0 kernel: Linux 3.8.1
N.B. I didn't use the latest traditional qemu because of the following bug:


Hmm.. isn't that bug affecting qemu-traditional in general, not
PCI/GPU passthru specifically?
Or is it *only* PCI/GPU passthru that it breaks for you?

PCI and GPU passthru work fine for me on 4.2.2 and 4.3.0
using qemu-dm (traditional), but only as long as I don't
assign > 2GB of RAM to a domU. I'm sure I saw patches
that were expected to address this that were also
supposed to be in 4.3.0, so either the patches didn't
make it into 4.3.0 for some reason, or the bug I am
hitting is a different bug with similar symptoms.

When I get around to it I'm going to set up a
Linux domU with GPU passthrough and > 2GB of RAM
so I can easily compare the memory maps and where
the GPU's BARs are mapped and see if there is an
obvious overlap where the memory stomp happens.
