Hello 
I have two Geforce GTX 1070 in my Computer. I want to passthrough one of them to a VM to run Windows. In VFIO/GPU Passthrough there is a guide GitHub - bryansteiner/gpu-passthrough-tutorial
But I don’t get the pattern for
Make sure to substitute the correct bus addresses for the devices you’d like to passthrough to your VM (in my case a GPU and SSD). Just in case it’s still unclear, you get the virsh PCI device IDs from the iommu.sh script’s output. Translate the address for each device as follows: IOMMU Group 1 01:00.0 … → VIRSH_…=pci_0000_01_00_0. Now create two bash scripts:
## Virsh devices
VIRSH_GPU_VIDEO=pci_0000_0a_00_0
VIRSH_GPU_AUDIO=pci_0000_0a_00_1
VIRSH_GPU_USB=pci_0000_0a_00_2
VIRSH_GPU_SERIAL=pci_0000_0a_00_3
VIRSH_NVME_SSD=pci_0000_04_00_0
My output from the IOMMU Script:
