XenServer 6.5 Pool Grid K1 VMs can only communicate with Nvidia associated passthroug whole GPU

Hi ,

we have a Xen Server Pool (Xen Server 6.5) with 3 Xen-Servers , two Xen-Servers have a K1 Gridcard inside.

I installed the binaries on both Xen-Servers.
lsmod | grep nvidia shows:
nvidia 10548578 26

nvidia-smi shows:

First of all i wonder, why the Output from lsmod shows not the additional line (documented in Adminstrationsguide):
i2c_core 20294 2 nvidia,i2c_i801
!!??

I can see the GPUs in my XenCenter and associated to Virtual Machines, but unfortunately i did not see the graphiccard in Device Manager and so Driverinstallation failed , because did not found Hardware .

Any help are much appreciated.
Kind regards
Marco
