GPU-Passthrough-Arch-Linux-to-Windows10 VS vfio

I'm not sure I'd describe the process as "sane", but I basically did as described in this guide[0], followed by following the setup guide for Looking Glass[1].

I followed this and this guides, and managed to isolate the card. Sadly, every single time i try to install the OS, the system freezes, and is said to be paused by virt manager. I cannot unfreeze it, and i don't know how to troubleshoot it. I also tried to do a normal installation (without passthrough), and it still froze

This is for Arch. But should be doable on any distro.

Here is the guide for Arch Linux just in case if you want to disregard the advice above. The differences amount to a different package manager and a different initramfs generator (so, steps 2 and 3 of that guide become different, and apt should be used instead of pacman). For PopOS, you will need to edit the /etc/initramfs-tools/modules file (and just list the needed modules) and run update-initramfs -u -k all.

Hi, My main focus is to use "moonlight host" in the win10 VM, I have an Nvidia 880M (discrete GPU) and the host GPU is a cheap Intel graphic card. I've used this beautiful guide: https://github.com/vanities/GPU-Passthrough-Arch-Linux-to-Windows10 to configure VFIO and libvirtd.

GitHub - vanities/GPU-Passthrough-Arch-Linux-to-Windows10: GPU Passthrough and virt-manager walkthrough

I was mainly following this guide to setup the VM and scripts: https://gitlab.com/Karuri/vfio

I've successfully set up single GPU passthrough as per https://gitlab.com/Karuri/vfio and https://github.com/joeknock90/Single-GPU-Passthrough .

- and a few other things mentioned here and here,

great thanks for the tip! havnt checked the logs for libvirt as i thought it was an osx issue. im using manjaro host, and have originally installed the vm using this https://github.com/foxlet/macOS-Simple-KVM, and this for the passthrough https://gitlab.com/Karuri/vfio

I used to have an RX580-based single GPU passthrough setup. You likely need the vendor reset module, since hot-plugging Polaris 10 GPUs is a bit buggy and can cause GPU lockups. It might also be worth dumping your GPU bios and configuring libvirt to use it so you get a visible boot screen (tool). I think I mostly followed this guide, however it hasn't been updated in quite a while it seems.

If you're up to the task you can follow this guide to get it working.

vfio-single-gpu-passthrough (this is for single gpu system, I link it for the section regarding hugepages, isolation, pinning & cpu governor which massively improved performance. It use script to dynamically run these only when you start a vm, so you can still use all of your cores when you stop the vm)
