Yes, Linux VM update to a 3.18 kernel.
The RHEL7.2 default kernel (should be 3.10) VM don't boot up with IGD
pass-through, and Windows can't boot up either.

"can't boot up" means guest doesn't boot at all, guest will stop to booting
after adding vga device, detail log in attachment.

Hao, Xudong would like to recall the message, "[Xen-devel] [PATCH v4]
igd-passthrough-i440FX: convert to realize()".
with latest qemu (without any
additional patch), guest run 3D "nexuiz" and get 180fps.
Will try the two patch together later.
