Hi,
I have two Nvidia Cards ( GTX750 Ti and GTX960 ). I want to passthrough
the GTX960 into a vm with windows, the other one should be used for the
Host with the propietary kernel module of Nvidia.
My settings:
Boot options:
GRUB_CMDLINE_LINUX="intel_iommu=on i915.enable_hd_vgaarb=1
init=/usr/lib/systemd/systemd"
When I prepare the 2 pcie devices with: (01:00.0 being the GTX750 Ti and
02:00.0 the GTX960)
echo '0000:02:00.0' | sudo tee
/sys/bus/pci/devices/0000:02:00.0/driver/unbind
echo '0000:02:00.1' | sudo tee
/sys/bus/pci/devices/0000:02:00.1/driver/unbind #(hdmi audio device)
echo 10de 1401 | tee /sys/bus/pci/drivers/vfio-pci/new_id
echo 10de 0fba | tee /sys/bus/pci/drivers/vfio-pci/new_id
I can see that for kernel driver in use it then is vfio-pci for both
devices, but for the graphic device there is still kernel module in use:
nvidia.
I guess that is my problem, because the vm freezes instantly ( the
cursor in the monitor window blinks two times and then stops ), and
there is no output on the monitor connected to the GTX 960.
I need the nvidia module for the GTX750 Ti Device.
Is that my problem, or sth different? Is there a way to prevent the
nvidia module to register for both cards?
Here is my qemu command:
qemu-system-x86_64 \
-enable-kvm \
-cpu host,kvm=off \
-soundhw hda \
-M q35,accel=kvm \
-bios /usr/share/qemu/bios.bin \
-smp 8,sockets=1,cores=8,threads=1 \
-drive file=w7.qcow2,if=virtio \
-m 2048 \
-vga none \
-net bridge \
-net nic,model=virtio \
-device vfio-pci,host=02:00.0,rombar=1,x-vga=on \
-device vfio-pci,host=02:00.1
Thanks for help!
