This last option makes sense to me: in a real world the user has

not with qemu?
Yes, the user build the machine using the command line and monitor
(or, in 2017, the machine configuration file),
Considering pbrook just posted a machine config for arm, I think it
would be rather sad if pc wasn't converted to it by 2017...
I'd be sad too, but not surprised.
then turns on the power. Command line options are the parts lying
around when we start.
btw, -drive needs to be separated:
-controller type=lsi1234,pci_addr=foobar,name=blah
-drive file=foo.img,controller=blah,index=0
-drive file=bar.img,controller=blah,index=1
Drives to not have pci addresses.
Drivers don't have indexes and buses but we specify it on the -drive
line.
Drives do have indexes. On old parallel scsi drives you set the index
by clicking a button on the back of the drive to cycle through scsi
addresses 0-7. An IDE drive's index is determined by the cable
(master/slave). A SATA drive's index is determined by which header on
the motherboard the drive connects to.
If by bus you mean the if= parameter, then drives certainly do have
buses. Just try connecting the scsi drive from the previous paragraph
to a USB port.
-drive is convenient syntax. It stops being convenient when you force
it to be two options.
controller= defaults to some builtin thing which autoinstantiates when
necessary, so the old -drive syntax works.
