[Xen-API] XCP 1.6 and GPU passthrough



Hello,

I'm running XCP 1.6 and I installed an ubuntu 12.04.02 as a VM. My machine has two GPU M2070Q and I'd like to do PCI passthrough to allow my VM to use those GPUs.

I modified the /boot/extlinux.conf to add the option "xen-pciback.hide=(02:00.0)(02:00.1)(83:00.0)(83:00.1)" as PCIDEV_BACKEND is built in the kernel (according to /boot/config-2.6.32.43-0.4.1.xs1.6.10.734.170748xen

I rebooted XCP but when I run lspci in dom0, pci devices 02:... and 83:... are still listed.

I set parameter other-config in my VM by doing:
xe vm-param-set other-config:pci=0/0000:02:00.0,0/0000:02:00.1,0/0000:83:00.0,0/0000:83:00.1 uuid=b6fcf...

But when I start the VM I got the following error:

The server failed to handle your request, due to an internal error. The given message may give details useful for debugging the problem.
message: xenopsd internal error: Xenctrl.Error("38: Function not implemented")

I tried to replace xen-pciback.hide= by pciback.hide= as I saw both on google but both have the same effect.

Any hints? I also like to know if someone already achieve to do PCI passthrouhg with a 3D graphic card on XCP 1.6? If yes can I have its recipe :)

Thanks everyone for you help,
Best regards,

Guillaume
