When I start the VM with the command virsh start WIN-DEV-SRV In /etc/default/grub file, I have this line: GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset intel_iommu=on i915.enable_hd_vgaarb=1" My device doesn't contain any other device so my IOMMU group I this is correct! I want to pass the device with code 03:00.0
I have followed all steps from this tutotial ( ) and bellow I have the results:

I have read a lot of tutorials about how to pass the secondary GPU on virtual machine but the things are really confusing because most of then use a graphic card which supports UEFI. I use KVM and I want to pass into my vm the NVIDIA GTX 660Ti graphics card which doesn't support UEFI. Passthrough a USB audio controller and use a loopback. You lose access to that device on the host. Passthrough a PCI device, whether that’s the graphics card’s audio controller or the integrated audio controller.
Slightly harder to set up, but no monitor needed. Therefore next step will be trying to do some overclocking based on this guide and that one.I'm using Debian 10 (Testing) with kernel 4.19.0-5_amd. Configure Qemu to connect to your desktop environment’s PulseAudio instance. Since I’m back to using Nvidia video card on Linux, I can no longer utilize ASUS tweaking utilities.

Make sure to select vdpau as output driver in your favourite multimedia player ( SMPlayer, etc.) to utilize hardware acceleration. Now just restart computer and enjoy – PCI-E video card should be nicely recognized by host operating system. There is one more file to edit: sudo nano /etc/initramfs-tools/modulesĬomment following modules which you’ve added when setting up VGA passthrough: # vfioĪfter editing this file initramfs must be updated: sudo update-initramfs -u Now edit following file: sudo nano /etc/modprobe.d/nfĪnd comment options line where your PCI-E card is mentioned: # NVIDIA Corporation Device You should know device IDs of VGA and HDMI of your Nvidia card: ~ $ lspci -nn | grep NVIDIAĠ1:00.0 VGA compatible controller : NVIDIA Corporation Device (rev a1)Ġ1:00.1 Audio device : NVIDIA Corporation Device (rev a1)

I did check if proprietary Nvidia driver for Linux was installed – it was: sudo apt-get update nvidia-384 nvidia-settings nvidia-modprobeĪctually there was a problem at the stage when system takes over PCI-E card somehow making it unavailable for host system.
GRUB bootloaded was showing up after plugging monitor to HDMI socket but login screen of Linux Mint didn’t come up. Now when problem occured is when I decided to switch to PCI-E video card (Nvidia GeForce) from Onboard (Intel) in BIOS. In addition to that my favourite Logitech G G920 Driving Force steering wheel had connection problems, so I decided to ditch Windows 10. On PCI-E slot I’ve got ASUS GeForce GTX 1070 TI which has both Nvidia driver pack along with ASUS tweaking and overclocking utilities which from time to time got uninstalled or otherwise broken.

And most important, device drivers gets messed (probably because of Windows Updates). Microsoft Windows 10 turned out to be a nightmare – user interface differs too much even from Windows 7 (which I’m kind of used to due to daily job where I can’t choose OS), updates are pushed and installed whenever Microsoft wants and there is no easy “official” way to turn them off. Instead, I’ll describe how to take PCI-E card back for use on host system (in my case Linux Mint). 01:00.0 VGA compatible controller: NVIDIA Corporation TU104M GeForce RTX 2080 Mobile (rev a1) Subsystem: NVIDIA Corporation Device 0000 Kernel driver in use: vfio-pci Kernel modules: nouveau, nvidiadrm, nvidia 01:00. There are great guides how to setup VGA passthrough and even run it on unprivileged user, so I won’t go into details about setting up virtualization in this post.

In such way Windows see not virtual VGA (as it would be on VirtualBox or VMware) but actual physical one plugged in to PCI-E slot therefore providing use of official Nvidia driver and full acceleration. Hardware virtualization software Quemu/KVM was pretty much the only way to do VGA passthrough – use integrated Intel video card on host system and provide Nvidia GPU equipped one to virtualized operating system. Several months ago I’ve setup Qemu on my Linux Mint powered workstation to have Windows 10 virtualized for gaming.
