  Thanks. So if I’m already UEFI booting my VMs with dedicated volumes, the key difference is how GPU pass-through is done?

    Pretty much, lots of factors that are hardware dependent, such as how your motherboard assigns IOMMU groups come into play.

You can also pass through more than just a GPU. I pass through an NVMe disk and a USB controller, effectively giving me a full second computer within my workstation. It's honestly fantastic.

  Ok. And I assume that’ll all work at PCI speeds making it much more performant than using virtio-based forwarding. Sounds neat. Do I need to do anything besides UEFI boot my virt-manager (QEMU) VM to make use of things like this?

    I generally followed this guide, despite working from another distro: https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF The biggest pain every time I've done this is making sure that I can bind the device to the vfio driver.
