According to the file pci-ids.txt in qemu sources, the range of PCI
device IDs assigned to virtio_pci is 0x1000 to 0x10ff, with a few
subranges that have different rules regarding who can get an ID
there and how.
Nevertheless, the full range should be assigned to the generic
virtio_pci driver, so that all corresponding devices, including
the experimental/unreleased ones "just work".
