I have just applied IGD VGA Passthrough patches to Xen 4.4-unstable
changeset 27238. Please refer to the 2 attached patches.

1. [Xen-devel] [PATCH 2/3] V4 qemu-xen-trad: Correctly expose PCH
ISA bridge for IGD passthrough

2. [Xen-devel] [PATCH 3/3] qemu-xen-trad: IGD passthrough: Expose
vendor specific pci cap on host bridge.

These are the steps I took to patch, compile and install Xen
4.4-unstable changeset 27238.

hg clone -r 27238http://xenbits.xensource.com/xen-unstable.hg
cd xen-unstable.hg-cs27238
sudo -s
make world
make clean
cd tools/qemu-xen-traditional-dir-remote
patch -p1 < patch2of3.txt
patch -p1 < patch3of3.txt
cd ../..
make world
make install

However, I still encountered problems installing Intel HD Graphics
display drivers. The driver installation would auto detect the
display adapter, causing the LCD monitor to blink 1-2 times. But
after that, the LCD monitor goes into Power Saving mode (blank
screen) forever again. I tried to destroy the Windows 8 HVM domU and
restart it. Windows 8 HVM domU would start up for a few seconds,
then falls back to blank LCD monitor screen forever again.

Did you try installing the driver *before* enabling IGD passthru? (if that's

It's not possible. The Intel HD Graphics display driver does not
allow me to install the graphics driver without the existence of
Intel HD Graphics 4600 IGD.

Is there any other workaround?

- Are you using qemu-traditional for sure?

Yes, please refer to the attached Windows 8 HVM domU configuration file.
- Are there any cmdline options for the Intel driver installer to install without the device present?

I have read through the installation instructions. There doesn't appear to be any cmdline options for the Intel HD graphics driver installer to install without the device present. Anyway, I have attached the installation instructions for you to read through.
- Any errors in the Xen dmesg? How about qemu logs? dom0 dmesg?
Attached xl-dmesg.txt, qemu-dm-Windows8.log and dmesg.txt.

Please advise on how to overcome the problem of installing Intel HD Graphics drivers.

Thank you very much.

Yours sincerely,
