The current code for using -drive simply sets the -drive 'index' parameter. QEMU internally converts this to bus/unit depending on the type of drive. This does not give us precise control over the bus/unit assignment though. This change switches over to make libvirt explicitly calculate the bus/unit number. In addition bus/unit/index are actually irrelevant for VirtIO disks, since each virtio disk is a separate PCI device. No disk controller is involved. Doing the conversion to bus/unit in libvirt allows us to correctly attach SCSI controllers when required. * src/qemu/qemu_conf.c: Specify bus/unit instead of index for disks * tests/qemuxml2argvdata/qemuxml2argv-disk*.args: Switch over from using index=NNNN, to bus=NN, unit=NN for SCSI/IDE/Floppy disks
