1af4:1040 Start of ID range for modern virtio devices. The PCI device
to ID is calculated from the virtio device ID by adding the
1af4:10ef 0x1040 offset. The virtio IDs are defined in the virtio
specification. The Linux kernel has a header file with
defines for all virtio IDs (linux/virtio_ids.h), qemu has a
copy in include/standard-headers/.
1af4:10f0 Available for experimental usage without registration. Must get
to official ID when the code leaves the test lab (i.e. when seeking
