Xen users - Jul 2013 - Is my Intel HD Graphics 4600 Xen VGA Passthrough to Windows 8 Enterprise HVM domU Considered Successful?

Hi,

My Windows 8 Enterprise HVM domU configuration is as follows. I have to 
*disable* gfx_passthru, that is, gfx_passthru=0. Please take note.

So is my Intel HD Graphics 4600 Xen VGA passthrough to Windows 8 
Enterprise HVM domU considered successful?

I cannot enable gfx_passthru, that is, gfx_passthru=1. If I enable 
gfx_passthru, Windows 8 Enterprise HVM domU would start for a few 
seconds, then the LCD monitor would go into power save mode (blank 
screen) *forever*.

Please advise me on how I can get VGA passthrough to work with 
gfx_passthru=1.

Thank you very much.

 Can you elaborate why exactly do you need to have that GPU passed
 through as primary? Primary GPU passthrough has always been
 problematic because domU has to re-post the card''s BIOS which
 has always been problematic.

 The only difference in the general case is that with gfx_passthru=1
 you get to see the POST and boot information on the monitor
 connected to the GPU. With gfx_passthry=0 you can only see this
 in the VNC session connected to the virtual primary VGA card. In
 the vast majority of cases seeing the POST and boot animation
 isn''t useful enough to be worth bothering with.

 I have a working setup with 2x Quadro cards, each passed through
 as secondary (gfx_passthru=0) to different domUs, with separate
 mice/keyboards passed through to each domU (multi-seat gaming
 rig), and that works lovely (only limitation being 2GB of RAM
 for each domU until I get around to upgrading to 4.3).

 Unless you have a very compelling reason to use gfx_passthru=1
 I suggest you don''t bother even trying.

Dear Gordan,

I want to use the monitor connected to Intel HD Graphics 4600 directly. 
I don''t want to use a VNC session to connect to the Windows 8
Enterprise
HVM domU.

Thank you very much.

 You only need VNC for the POST. Once Windows boots up you should be
 be able to get all your display output on the physical screen.
 Disable the virtual VGA interface in device manager if you have
 to - I''ve found that is sometimes necessary to get the physical
 GPU working properly.

Hello Teo,

I presume that Gordan means this: http://i.imgur.com/8OjstX4.png

While there''s probably a dozen ways to access it, most folks generally
right click the desktop and click "Screen Resolution."  I''m
sure
you''re aware of how to get there though :)

Andrew

Hi,

When I tried to change the settings in "Screen Resolution", I always
get
this error:

http://i.imgur.com/idb6Cf4.png

It seems that the Intel HD Graphics 4600 display driver may be unstable.

Although I can access the settings as shown below, I can''t change them.
And I don''t know how to change them as well.

http://i.imgur.com/YGw9MdQ.png

http://i.imgur.com/5zH2edv.png

If I try to change any of the settings, I will get an error similar to 
this below.

http://i.imgur.com/idb6Cf4.png

Any advise?

First of all try with Windows 7 instead of Windows 8. 
People have reported using gfx_passthru=1 with IGD with Windows 7 successfully.

Dear Pasi,

I have just tried out with Windows 7. I appear to have some *small* 
success with Intel HD Graphics 4600 VGA passthrough to Windows 7 
Ultimate HVM domU.

However, the monitor has 16 colors only!!! Please refer to the following 
screenshots.

http://i.imgur.com/kOopamo.jpg

http://i.imgur.com/aEmKKyc.jpg

As you can see from the above screenshots, there are only 16 colors on 
the display!!!

So is my Intel HD Graphics 4600 Xen VGA Passthrough to Windows 7 
Ultimate HVM domU still considered successful?

Well, for some reasons unknown to me, I cannot change the number of 
colors on the monitor. And one more thing, the LCD monitor will blank 
screen after a while.
