However, in order to retain compat for that SCSI device (e.g. ensuring

figure
out what address to use, libvirt would need to query qemu for

PCI address allocation itself ...
This last option makes sense to me: in a real world the user has
control over where he places the device on the bus, so why
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...
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. -drive is convenient syntax. It stops being convenient when you
force it to be two options.
