Re: [Xen-users] VGA Passthrough, multiple cards/vms

[Casey DeLorme <cdelorme@xxxxxxxxx>]

I may have misunderstood; do you have two discrete cards and one integrated? ÂIf you have only one discrete, are you using SSH to access Dom0?

In my case I chose a Debian Dom0 (control OS) and left the IGD there, I have not passed it to a machine. ÂPassed devices are not shared, so I would have to hide the IGD from Dom0 to pass it to an HVM, which would mean accessing Dom0 through SSH.

Unfortunately I am still quite inexperienced with how Linux handles graphics in general, and have not had the time to experiment with passing my ATI to a Linux HVM.

Hi Casey,
I just checked your tutorial.
I'm also trying a build with i7 3770 + Asrock H77m-itx board, to pass through HD4000 IGD.
I'm currently having a debian domU working, but got problems with win7 HVM.
As you mentioned in your tutorial, installing with the device passed is problematic.
I've seen many BSOD that appears to be irrelevant (system_service_exception, memory mangement etc), but only appears when IGD is passed through.

With emulated graphics card + IGD as secondary, I can finish the OS install. But once the intel display driver is installed, same BSOD comes back.

Could you share a little more how do you installed your drivers?

Thanks,
Timothy

The guide should still be accurate, though I am now using 4.2 stable and Kernel 3.6 (3.5 is bugged).

The guide has links to a complete video run-through as well. ÂFollowing the instructions should take a few hours, understanding everything about it may drive you to drink all your bourbon.

Totally doable. ÂI'd link you directly if I had more time to type this
email, but Casey DeLorme posted to this list a full written and video
tutorial that does just this. ÂIntegrated graphics go to Dom0 (running
Debian) and a Radeon card goes to a Windows DomU.
