[Xen-users] VGA Passthrough with Linux guests

[Steven Seed <steven.seed@xxxxxxxxxxxxxxxxxxx>]

I've been doing some research and have seen the success by David Techer and Teo En Ming in getting a Windows guest to work with VGA passthrough under Xen but I'm wondering if anyone has been able to get it working with a Linux guest. Specifically, I'm trying to run a RHEL 6.4 guest with a Nvidia Quadro graphics card. At the moment, I'm running XCP 6.1 which  is xen 4.1.3-1.6.10 under the covers. I'm not sure if this will work or not. I've got a hvm guest running and I've been able to assign the GPU to it. I'm at the point where the Nvidia driver loads and I can see a card in the guest with lspci, however the GPU isn't functional and I get a black screen. I think the issue may be vgabios related because if I cat /proc/driver/nvidia/gpus/0/information I get this:

Model: Quadro K5000

IRQ:   40

GPU UUID: GPU-????????-????-????-????-????????????

Video BIOS: ??.??.??.??.??

Bus Type: PCI-E

DMA Size: 32 bits

DMA Mask: 0xffffffff

Bus Location: 0000:00.06.0

If there are patches I need to make this work, I'd appreciate a pointer. I tried following Teo En Ming's document from here: 

http://wiki.xen.org/wiki/Xen_VGA_Passthrough#Status_of_VGA_graphics_passthru_in_Xen

But unfortunately, at least over the last few days, I can't get the patches referenced at http://www.davidgis.fr/download because the site is down. 

Does anyone have these patches and do you know if they can be applied to XCP 1.6?
