[ovirt-users] Nvidia Grid K2 and Ovirt GPU Passtrough

Hello, i have tried every documentation that i found to bring GPU Passtrough with a Nvidia Grid K2 to ovirt, but i failed. I am confident that it has to run with my hardware, but i have no ideas anymore. Maybe the community can help me. Actually my VM (Win7 and Win10) crashes or hangs on startup. I have done theese steps: 1. lspci -nnk ......... 07:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK104GL [GRID K2] [10de:11bf] (rev a1) Subsystem: NVIDIA Corporation Device [10de:100a] Kernel driver in use: pci-stub Kernel modules: nouveau 08:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK104GL [GRID K2] [10de:11bf] (rev a1) Subsystem: NVIDIA Corporation Device [10de:100a] Kernel driver in use: pci-stub Kernel modules: nouveau ......... 2. /etc/default/grub ......... GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=cl/root rd.lvm.lv=cl/swap rhgb quiet pci-stub.ids=10de:11bf rdblacklist=nouveau amd_iommu=on" ........ 3. Added Line "options vfio-pci ids=10de:11bf" to nano /etc/modprobe.d/vfio.conf dmesg | grep -i vfio -> [ 11.202767] VFIO - User Level meta-driver version: 0.3 [ 11.315368] vfio_pci: add [10de:11bf[ffff:ffff]] class 0x000000/00000000 [ 1032.582778] vfio_ecap_init: 0000:07:00.0 hiding ecap 0x19@0x900 [ 1046.232009] vfio-pci 0000:07:00.0: irq 61 for MSI/MSI-X ------------------------------------------------------------------------- After assigning the GPU to the VM, the OS hangs on startup Any ideas?
