Hey guys,

I am trying to passthrough an Intel HD 2500 graphics card. My CPU is i5-3470 and chipset is Q77, both are supporting VT-x and VT-d. I am always getting a black screen. So is it generally possible to passthrough an Intel graphics card?

I tried to follow the steps in the following thread, but there is no end conclusion for this problem. http://forum.proxmox.com/threads/19078-GPU-passthrough-possible-with-my-hardware

Do I really need the VGA arbiter patch for i915 driver or is it implemented in the proxmox kernel? Or do I maybe need the newest kernel version from pvetest repository? https://lkml.org/lkml/2014/5/9/517

I saw in the kernel changelog that proxmox enabled vfio xvga. Have they implemented the patch or is it something else? https://github.com/proxmox/pve-kernel-3.10.0/blob/master/changelog.Debian

If anyone can give me a solution it would be great!

Thanks,
Felix

Anyone?

Maybe somebody knows how to compile the proxmox kernel? I want to apply the patch for i915 driver, but first I wanted to compile the kernel from original proxmox source. I have downloaded the git repository from https://github.com/proxmox/pve-kernel-3.10.0 and tried to run "make" but after a while I got this error:
