Hi, Are you sure it hangs? or is just redirection of the graphics is not going to the console anymore? The second is my case, so I can ssh to the server and see it alive. But no idea how to set the graphicals properly. On 25/1/19 2:51, jarheadx@hotmail.de wrote:

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?

Do you ever stop at the boot screen? (Windows logo screen, etc.) You can not implement a GPU display with spice. There are some engineers who have implemented this functionality through upstream kvm, but they are not fundamentally supported by ovirt.
