[brought forward to current qemu-kvm.git] This patch implements the missing qemu logic to interpret a '-drive .. serial=XYZ ..' flag for a virtio_blk device. The serial number string is contained in a skeletal IDENTIFY DEVICE data structure and this structure is made available to the guest virtio_blk driver via pci i/o region 0.
