Oh, btw, I have no idea what the state of vfio-pci + QEMU on arm64 is. In case it's supposed to work, you could give https://lkml.kernel.org/r/20201119153918.120976-1-david@redhat.com to see what we're missing. I added a short virtio-pci guide to https://virtio-mem.gitlab.io/user-guide/user-guide-qemu.html -- Thanks, David / dhildenb
