Update:
I'm now able to install debian on domU.
The issue I mentioned before is due to a silly mistake of incorrect nfs permission setting.
Basically this time I can see linux desktop on TV panel. However, it is still not fully working.
Even 2D looks perfect, 3D acceleration is not working at all
For 3D, glxinfo report looks good, but glxigears does not render anything.
Only once among many times I can see a set of static gears instead of running ones.
I also tried xbmc, a gpu accelerated program and basically it doesn't work.
But frankly I could still switch to console (KMS) even when the fullscreen 3D app appears to be hanging.

And this time I can't have the audio working (even it did work for the openelec os img).

There seems to be some problems about interrupt routing and lead to missing interrupts according to logs:

I had been trying to install win7 && debian as domU these days and the result is frustrating.
For win7, I was able to install and got video output on TV.
But it simply BSOD once intel driver is installed.
The BSOD says something about SYSTEM_SERVICE_EXCEPTION. not sure what does it means.

Also, the TV screen starts to flashing with random colors once I get the win7 VM reboot.
I need to assign the VGA controller back to host once and then to pciback again to have it back to work.
Quite annoying.

For debian, I tried both debian 6 / Wheezy installer. Both of them hang when trying to partition the disk xvda.
I tried to manually use fdisk && dd to access the device and it seems that the access never got response.

Oh... DQ77MK has DVI-I, DVI-D and HDMI so it's a little different.

The fact that Win7 installer outputs makes me further suggest that you try another Linux domU.

When I get home I'll try to assign the USB 3.0 controller to a domU and let you know.

Update: DVI output does not work either for the openelec 2.0 domU.
The intel HD4000 seems does not have internal DVI output.
The xrandr shows that the on-board DVI port is converted from an internal hdmi output (hdmi1 this time).
So I won't surprise that it does not make any difference.

However, another experiment brings some positive result -- the win7 installer actually showed some output on TV.
I'll try to finish the install and see what will happen with an Intel driver.

Haven't tried to passthrough the USB 3.0 controller both the 2 USB 2.0 controller pass just fine.

Try to setup another Linux domU for example Wheezy or Ubuntu 12.04 LTS. Those are guaranteed to worked.

No, this is the first VM so far.

I tried to upgrade the bios and it does not help. Haven't try out DVI port yet. Will do it later.

PS: I can now confirm that the usb ctlr also works -- I can get data by open the device file directly.
However, it only works for USB2 ctlrs (at least before bios upgrade) -- system complaining that it cannot reset the xhci controller.
What about yours?

Here comes the logs, compressed to save traffic:

/var/log/xen/qemu-dm-<vm-name> and <vm-name>.cfg would be used.

Btw did you try doing IGD passthrough to another Linux domU?
