nvidia.ko does not support dynamic unbinding of devices. I've filed a
bug with them, they closed it wontfix. You need to follow the guides
to have the VM graphics card bound to pci-stub or vfio-pci directly
rather than letting it bind to nvidia. See for instance

Forgot to send it also to the mailinglist...
Ok sry, after double reading it, I understood that this pci ids are
generic for any nvidia or amd cards, so I'm not allowed to use them
because I need one nvidia card for my host.
I set up dracut with add_drivers+="vfio vfio_iommu_type1 vfio_pci
vfio_virqfd" and vfio-pci with options vfio-pci ids=10de:1401,10de:0fba
because of:

That way it only affects my GTX960.
I did only use vfio-pci because thats available for my kernel (4.1.15)
and therefor I don't need pci stubs and is not recommended as vfio-pci
is the newer way.
Any chance a newer kernel would fix my problem?
But as you can see for Kernel module is still nvidia put in :/. Did I do
sth wrong? Or perhaps this is normal and no problem because of Kernel
driver in use: vfio-pci is correct?
Is the nvidia module per default in dracut ( so I would need to remove
that from the initrd)?
