Complete-Single-GPU-Passthrough VS Single-GPU-passthrough-amd-nvidia

I was trying to get single GPU passthrough to work on my RX 6700xt and Ryzen 5 5600 however after following this guidehttps://github.com/QaidVoid/Complete-Single-GPU-Passthrough I can no longer even launch any VMs or create any new ones. I get this error.

Im assuming you're on a single gpu setup and, as such are trying to do single gpu passthrough with a single nvidia card. so you'll likely have to run some libvirt hooks or smth to run scripts to unbind your gpu once you start your vm. In which case id suggest going through these two guides 1 2 which go over completely passing through your single gpu when you start your vm

Thanks for reply. I didn't find the issue, but I decided to install endeaveour just to not reinstall arch every hour and using this guide I managed to make it work. I guess on bare bones system I missed something every time I tried, but I'm not experienced enough to know what I didn't do to run it.

I have a similar use case. I good good guide to follow would be this but I also have my iGPU disabled completely.

not an expert on this, but you can use the single gpu passthrough scripts to unload/reload drivers for host/vm needs. (no reboots) ssh into the desktop pc and test out what works for you. https://github.com/QaidVoid/Complete-Single-GPU-Passthrough what helped me here was unbinding/binding the vtconsoles before unloading/loading drivers again via tty. If you do it directly on the machine, you may lose tty/framebuffer, which is why I suggested ssh.

I used this and it worked. https://github.com/QaidVoid/Complete-Single-GPU-Passthrough

Hello. I have an RX 6600, and I wanted to use single gpu pass through. I followed this guide. Everything worked fine, until I got to installing the drivers. Once they got installed I got a black screen. I know it installed successfully because I used teamviewer to look at my screen from a different PC. Any help would be appreciated.

Hey, following this guide and when i try to install windows i get the following screen. This is my boot configuration. On all references and guides i could find this step was trivial so i'm a bit confused as to what might be going wrong.

https://github.com/wabulu/Single-GPU-passthrough-amd-nvidia but you need to use the command sudo bash instead of sudo install. The other guide i found very helpful is https://gitlab.com/risingprismtv/single-gpu-passthrough/-/wikis/home

It is possible to do single-GPU passthrough but I've never tried it myself. It requires the right sort of hardware to work AFAIK. Here's a guide I found for it: GitHub - wabulu/Single-GPU-passthrough-amd-nvidia

make sure you are on the latest commit, which is 3 days old. you can get it by either downloading it zipped and extracting or doing git clone https://github.com/wabulu/Single-GPU-passthrough-amd-nvidia.git

As for GPU passtrhough, you should be fine, spec-wise - however the only surefire way to test this is to actually test it on your hardware. I'd suggest reading through the following -> https://github.com/wabulu/Single-GPU-passthrough-amd-nvidia

I followed this guide for my 3080: https://github.com/wabulu/Single-GPU-passthrough-amd-nvidia. The guide also links to this guide which is very helpful. After getting it all set up make sure to also directly pass through your USB devices and Windows will detect everything as though it's natively installed.

Configure libvirtd and the VM .xml as instructed with https://github.com/QaidVoid/Complete-Single-GPU-Passthrough and https://github.com/wabulu/Single-GPU-passthrough-amd-nvidia/tree/3d8666e66d009493a3f5b574bdba15954ed86af5, carefully reading, understanding and adapting the steps (including removing virtual VGA and SPICE)

At first I would just get a black screen, but re did everything and follow this guide to the T. I was finally able to get to the GPU to passthrough and see the Windows VM. But now, if I install ANY drivers, either Windows Update, AMD drivers, AMD drivers Pro, etc, I cannot see anything and get a black screen. Thankfully I enabled RDP and did a bridge network so I can connecto to the VM but the only fix is for me to completely remove any GPU drivers. Any suggestions?

I recently set up a virtual machine with single GPU passthrough. Everything works perfectly fine until I shut down virtual machine, after that I have black screen with no signal. If I run VM through virt-manager I won't be able to do anything except of holding power button on PC to shutdown it, but if I run it through tty on black screen I can write "shutdown" and PC will actually shutdown. If I try to run startx everything will completely hang. I can run "DISPLAY=:0 sudo startx" through ssh and it will open dwm, but as a root user and I won't be abe to switch to any tty and doing it is inconvenient. Any idea how to make it work? Setting it up I followed this guide. I don't have display manager, tried to install and do it with sddm but result is the same.
