Links and scripts from Video: Tutorial: Debian 8, howto passthrough your physical GPU to your virtual Windows7 with KVM and OVMF

Here are the links and scripts.

Now is the successor of the archlinux forum part.
https://bbs.archlinux.org/viewtopic.php?id=162768
In Arch Linux You can find a nice and very active community, the first entry is a howto that addresses different configurations.

In VFIO blog are a lot of information regarding the hardware virtualization.

a list of working and non-working systems with different Linux distributions

My hardware components:
Intel(R) Core(TM) i5-4590 CPU @ 3.30GHz socket 1150
GA-Z97X-UD3H-BK
16GB DDR3 Memory
512GB SSD
NVIDIA GeForce GTX 780 (ASUS GTX780-DC2OC-3GD5) for passthrugh

To check do the video card supports UEFI Boot.

HOWTO Debian Jessie 8 pci_stub config to hide PCI devices from device modules

# If you have to hide a PCI device like a GPU, you can use pci_stub

# to get the PCI port of your PCI device you can use lspci

   lspci

#     ...
#     01:00.0 VGA compatible controller: NVIDIA Corporation GK110 
#     [GeForce GTX 780] (rev a1)#     01:00.1 Audio device: NVIDIA Corporation GK110 HDMI Audio (rev a1)
#     ...

# the GPU use the PCI Slot 01:00.0 and 01:00.1 for the Nvidia Audio device
# NOTE: It's important to passthrough both devices to the virtual machine.

# for pci_stub, we need the IDs, with "lspci -n" we see this IDs

   lspci
#     ...
#     01:00.0 0300: 10de:1004 (rev a1)
#     01:00.1 0403: 10de:0e1a (rev a1)
#     ...


# Use the grub cmdline for pci_stub initializations

sudo nano /etc/default/grub

# change GRUB_CMDLINE_LINUX_DEFAULT
# from "quiet" to
# "quiet intel_iommu=on pci_stub.ids=10de:1004,10de:0e1a"
# after save start update-grub

   sudo update-grub2

# Add pci_stub to the end of /etc/initramfs-tools/modules and update the initramfs

    sudo update-initramfs -u

# After this the pci_stub kernel line parameter is working.

# Now reboot and the given devices will not working until you wont this.
