    PSA for anyone using #QEMU #KVM for #SingleGPUPassthrough
    Guides are all over the net suggesting hooks scripts invoking pci devices, unloading/loading kernel modules, and other unnecessary things. Here's my current hook script for starting the VM:

    systemctl stop display-manager

    That's it. And the reverse for teardown:

    systemctl start display-manager

    #IOMMU groups still apply, and you need to pass the correct PCI devices to your VM, but everything else is handled automatically.

    Disclaimer that this is how it works currently for my AMD card. I did have a working setup with my NVIDIA card that did unload/load kernel modules, however it seems things have come a long way since I set that up.

    Drivers switch went about as well as I could have expected: failed to boot to GUI, then I banged my head against the wall for a while before finding a lingering xorg.conf I swore I'd deleted, then everything just worked!

    Trying to get #QEMU #KVM VM working today with #SingleGPUPassthrough . The VM itself is already set up, I just need to configure passing the GPU to the guest and installing drivers
