First of all, virtio-blk is an alias for virtio-blk-pci.  I should not 
have used it as it's likely confusing, but anyway "qemu-kvm -device 
virtio-blk-pci,?" tells you all the options that a virtio-blk(-pci) 
device can have.

The idea then is that when you want to express extra options, you cannot 
use simply "-drive if=virtio", and qdev-device-use.txt then hints about 
how to convert -drive if=virtio" to "-drive if=none" + "-device virtio-blk".
