Hello together,
i've got a problem with my GPU passthrough to my Windows 10 VM.
My Hardware is a HP Proliant ML310e. My Graphics Card is a Nvidia 750 with 2048MB RAM.
I can use only one PCIe Slot for this Card.
My Bios is the Version J04 11/09/2013. (newest)
I've read so much in this Forum and tested so much with PCIe ACS Override and the syslinux.cfg
This is the error Code when i try to start the VM with the Nvidia 750 GPU:
internal error: process exited while connecting to monitor: 2016-04-25T09:04:53.998337Z qemu-system-x86_64: -device vfio-pci,host=05:00.0,id=hostdev0,x-vga=on,bus=pci.2,addr=0x4: vfio: error, group 1 is not viable, please ensure all devices within the iommu_group are bound to their vfio bus driver.

I'm using this in the syslinux.cfg:
append intel_iommu=on vfio_iommu_type1.allow_unsafe_interrupts=1 pcie_acs_override=downstream initrd=/bzroot
Also tested PCIe ACS Override enabled/disabled.
My onboard Graphic Card is enabled. So the Console from Unraid goes to this Adapter.
The GPU is shown under devices.
05:00.0 VGA compatible controller [0300]: NVIDIA Corporation GM107 [GeForce GTX 750] [10de:1381] (rev a2)
05:00.1 Audio device [0403]: NVIDIA Corporation Device [10de:0fbc] (rev a1)
no other devices are using the Group of 05:00.0 and 05:00.1 when i use PCIe ACS Override enabled.
What can i try?
Many thanks.
