On 4:15 you prevent NVIDIA proprietary drivers from installing. I have AMD GPU - is there special syntax for that? Also one more question: let's pretend I isolated my second AMD GPU and passed it to VM. But still I want to play some games on my Linux OS. What are steps to un-isolate the hardware and bring it back to Linux?
to stop the AMD card from loading? use softdep radeon pre: vfio-pci and then under that softdep amdgpu pre: vfio-pci, that stopped my card from loading but my nvida is my second card and it loaded at the beginning I could see my kde plasma wheel then zippo no video at all on either card, the battle continues.
If anyone has issues booting after the first step. Boot into recovery mode and "nano /etc/default/grub". Then delete the line that you modified before and save the file. After that run "update-grub" and you should be able to reboot. 👍

I tried this tutorial but I wasn't able to bing the vfio-pci to the nvidia hardware, and mostly because, the modprobe described in the video expects to have the proprietary Nvidia drivers installed. If you are not using it, you have to changed it from `nvidia` to `drm` instead. My setup: - AMD with iGPU as host - With Nvidia card to guest OS
I have a Ryzen 7 7700 and I have an NVIDIA 2060, I wanted to use the nvidia por linux and the integrated AMD for WIndows but it seems not to work. The AMD does seem to passthrough but windows doesn't recognize it as an AMD it just shows the devices as PCI\x
As far as I can understand, having both GPUs from AMD (7600xt + 7800x3d's iGPU) I can choose what to use as passthrough but when it comes to disable the Linux drivers in the kernel Linux (host) the Linux host will be withouth GPU acceleration. Am I wrong?
Hey man… unfortunately one didn’t work. I have a beefy laptop with an NVIDIA quadro card inside but unfortunately it’s says: host doesn’t support pass through pci devices
Hi,really nice tutorial.. I have some questions- how to get full refresh rate supported by monitor? & how can i switch mouse and keyboard input between host and the guest cause my m&k just locks into virt guest when I run it.
Nahh, you probably gotta buy another pair.. Or allocate a few usb ports.. then keep switching the usb plug from the free usb ports to the vm allocated ones you've allocated to the vm.
Bluetooth is passed through automatically, if not, detect how it is connected and pass it through, also, make sure that Bluez drivers are installed on Linux.
this might sound weird, but theoretically: i have 2 4090s, and no igpu. assuming im deactivating the nvidia driver, wouldn't i also lose output of my other 4090 which i wouldn't pass on?
No, there doesn't need to be any cable plugged into your guest gpu. It's simply being used for its resources. Think about it - the guest PC isn't really plugged into your actual monitor; it's plugged into a virtual monitor / videocard created by the virtual machine host.
I have a question. Lets say after i've done with windows vm, and shut it down. Then i want to openup second vm (windows or linux). Does the gpu stuck on the first vm? can i use the gpu on the second vm?
Im experiencing an issue... I followed this tutorial on Ubuntu 22.04.3 and everything worked as expected, but when I tried to start the previously working VM, there is just a black screen. Im trying to pass through a 3090, using iGPU of my Ryzen 7600x for the host. Anyone know what I did wrong?
I finished the tutorial and the drivers for my GPU got installed, but for some reason in device manager, NVIDIA Platform Controllers and Framework is not running and it is causing the GPU to not activate in win 11. Debian 12 Buster.

I am a bios user and when I tried to create a win10 UEFI VM it didn't boot. and when I tried the passthrough in win10 BIOS VM it didn't work, it showed me an error saying "Your host device doesn't support PCI passthrough". What to do?
In the /etc/modprobe.d/vfio.conf file, on the second line, replace "nvidia" with "nouveau". Was just running into the same issue myself. I never switched to the nvidia drivers because I installed the Nvidia card specifically for this project.
@geonofone9816 thank you, I had this problem in ubuntu where I was running the nouveau driver, and ubuntu would start until after I followed your suggestion of replacing nvidia with nouveau in vfio.conf. Good call In my setup, I had to bypass both the nvidia and nouveau drivers.
I had the same problem. You can use a kernel patch (acs override or sth like that), this will seperate the devices into different IOMMU groups. Instead of manually patching the kernel, install the latest `xanmod` kernel (which includes the patch). With that I managed to launch my vm Edit: You will need to edit your grub confguration: `pcie_acs_override=downstream,multifunction`
I have kind of a dumb question. Being that you are isolating you dgpu away from the host, doesn't that mean the host system won't have access to it, and do you have to change the grub config back to undo that or does this not cause such problems?
Umm, everything went fine, the gpu gets detected in the devices in windows, but when i install the nvidia drivers the screen just goes black completely. then i have to remove the nvidia pcie device and start windows and uninstall nvidia drivers to make the screen visible....
I tried this and had zero video on reboot, do you have any instructions for doing this with AMD GPU and not nvidia? Luckily I could reboot to a generic instance and remove the lines from grub and reboot to get my main video back.
I'm on Ubuntu 24, and have two AMD GPU's - 1) PCIe card(7900), and 2) onboard AMD GPU.

@@kskroyaltech Hi, I tried it, but it is the same problem. Once I shutdown VM with virsh and try virsh -list the command hungs and I can't even reboot host anymore. I am pretty sure my problem is around detaching the VGA device: "virsh nodedev-reattach pci_0000_0a_00_0", which probably happens when you shutdown the guest. I tried to search internet, but no luck so far.
You can use it with HOST OS. Just remove VFIO.CONF file (sudo rm -f /etc/modprobe.d/vfio.conf) then update intiramfs. Now, remove all kernel arguments passed to grub, update grub and reboot. NVIDIA drivers will be loaded during the boot time, and will be made available to host OS to use NVIDIA.
@@kskroyaltech Exactly. How is it done? I wish to do some stuff using 2 monitors, but the 'screens' are from 1 VM. So that it's always isolated from my main OS/machine. I imagine, there should 2 Virt Manager windows for a single VM.
If Proprietary Nvidia drivers installed, it must be disabled through the VFIO.CONF. That way the Host OS rely on iGPU and leaving NVIDIA isolated. Then NVIDIA GPU can be passed through any VM .

He misspelled it. It's "mkinitcpio"
Do i need to install Nvidia drivers in the base machine ?
No need..
Or should I just dual boot? I assume if I want to use nvidia on host, i had to undo everything, and if i want it back on vm, basically redo it back.
Yes you can dual boot .
@@kskroyaltech i know i can, but im more asking should i or this is more convenient. but im guessing dualboot is more convenient in my case.
@@nightstar9. Dualboot is convenient in my case as well, I have a mini-ITX motherboard and there is only 1x16 pcie lane and don't want to bother with multiple GPUs.
If they can make a software that gives gpu to guest and then back to host, I am game.
@@nightstar9.you could make 2 grub entries one with and one without the iommu kernel options, and then you boot accordingly
@@kodehou Thanks for the idea
Followed this to a T and now my Ubuntu 22.04 freezes at boot after showing some logs before where the login screen would normally appear
Was also not able to boot into recovery mode and am currently having to repair my system using a live usb.
Windows working great with GPU path through, but the issue I can't solve is I am not able to shutdown Windows VM and return back to the host.
I am not even able to reboot the host via ssh, it is just dead and the only option is to force shutdown.
open terminal and try this command to shutdown windows VM first through this command:
*sudo virsh shutdown* then reboot the pc with
*sudo reboot now*
@@kskroyaltech
I can try it, thanks. So ssh remotely and try to shutdown VM with virsh command.
What I found is it when I try to reattach PCI device with "virsh nodedev-reattach pci_0000_0a_00_0" I am getting the black screen
and can't do anything else, but hard shutdown, even though VM is not even running.
@@kskroyaltech sudo shutdown -r now.
I need to re-create the VM today and I will try it tonight. Thanks again for your prompt reply.
@@kskroyaltech
Hi,
I tried it, but it is the same problem. Once I shutdown VM with virsh and try virsh -list the command hungs and I can't even reboot host anymore.
I am pretty sure my problem is around detaching the VGA device: "virsh nodedev-reattach pci_0000_0a_00_0", which probably happens when you
shutdown the guest. I tried to search internet, but no luck so far.
Is it avail in same laptop with GTX 1650??
Any GPU as long as you have a second GPU will work... (including integrated graphics)
for that it need mux switch i guess
@@tobihudiat
Bro you can almost pass ANY GPU to VM as long as your System is Having GPU 0 (iGPU).
Will i not be able to use the nvidia card on the host?
You will not be able to use the card on the host because it is blacklisted from the distro to get used by the VM.
You can use it with HOST OS. Just remove VFIO.CONF file (sudo rm -f /etc/modprobe.d/vfio.conf) then update intiramfs.
Now, remove all kernel arguments passed to grub, update grub and reboot. NVIDIA drivers will be loaded during the boot time, and will be made available to host OS to use NVIDIA.
@@kskroyaltech will pass through still work?
@@korigamik no, because all of that work for the vfio is now gone... you need to reassign it yet again to vfio
@@kskroyaltech Can you please tell how to remove it from kernal detailed please
ok but what if I am trying to use my 5700G's Integrated Graphics instead of Nvidia?
Thank so much, peace and love
i found you can skip the grub commands
You mean I skipped any Commands in the description ?
@@kskroyaltech i dont use grub found everything else works without grub or intramfs
@@kskroyaltech no some pf them are not necessary
Thank you so much for the video! Please tell me, will it be possible to create two virtual machines in this way?
yes you can create. But I am not sure once you pass a GPU to particular VM , I guess you cannot use it with other VM until the VM is shutdown.
lspci -nn | grep -E “NVIDIA” doesnt show pci ids, i am using ubuntu 23.10
it will work. Make sure you have typed correctly.
@@kskroyaltech It doesn't show audio controller of nvidia, only video, so please help me what should I do
it will work in arch linux ?
YES give a try.
how to switch between them ?
@4:25 theres a typo , its sudo mkinitcpio -p linux
Which distro you are using ?
@kskroyaltech Arch
How do we use 2 separate monitors for 1 VM?
You mean to use the SAME VM on TWO monitors. ?!
@@kskroyaltech Exactly. How is it done? I wish to do some stuff using 2 monitors, but the 'screens' are from 1 VM. So that it's always isolated from my main OS/machine.
I imagine, there should 2 Virt Manager windows for a single VM.
@@kskroyaltech Do you know how to?
Is windows to linux possible?
Thankss,, can we use for kvm hackintosh?
I didnt try that but check out this GitHub link:

It doesn't give me the option "Browse"
Does GPU passthrough work with Arch Linux VM through Ubuntu Host
It will work. I didn't try ..
@@kskroyaltechare the config files for the host & the guest for the VFIO pass-through to work is OS specfic?
Is it possible to do this with one GPU?
Technically YEs, but you end up with Bootloop... So not recommended.
Does it work for windows?
NO
Can we use proprietary nvidia drivers?
If Proprietary Nvidia drivers installed, it must be disabled through the VFIO.CONF. That way the Host OS rely on iGPU and leaving NVIDIA isolated. Then NVIDIA GPU can be passed through any VM .
@@kskroyaltech okay
@@kskroyaltech My system wont boot while trying to isolate my Nvidia RTX 2070m gpu any solutions, it has Intel integrated graphics as well.
@@kskroyaltechdoes this config also work if i install fedora linux in the kvm guest ?
@@kskroyaltechmay i ask will the config in this also work if i installed linux in kvm guest?
really good, thanks
Bro PC not turning on 😢
What is the problem bro
One giant leap for man, one small step for Microsoft.
am setting this up because Lutris installing EA launcher an general wine game installs hate me so am doing this till a games to much for it XD
Please create install macos in windows with gpu pass through
I’m not sure how to do that.
It doesn't boot on Linux Mint Host
Any error you are getting.
The nvidia probe routine was not called for 1 devices
I got bad luck, my pc only have one gpu
thanks for the vid, i get a message about opengl not working, how should i fix that? :D
make sure 3D acceleration is turned on using Virtio. QXL doesn't have 3D accleration support.
@@TheJason13 yeah, i get an error message 😿
Excellent video! Is it possible to accomplish this using a single GPU?
Yea, but you computer must has a iGPU and atleast one Discrete GPU
@@kskroyaltech i have AMD RX 580 (8GB flashing for mac boot)
and opensuse thumbleweed...
so can I run this tutorial with a single GPU?
I'm worried about causing damage :)
Could you make a tutorial for Fedora?
Almost similar, but to update intiramfs you need to dracut. Anyway will try making a video
Near native GPU performance? This is the part you should likely correct in this video.
Yep with Windows 10 You will get close to Native GPU performance when it configured properly.
This caused my linux partition to be unbootable. Thanks
