./x86_64-softmmu/qemu-system-x86_64 -device ahci -drive
id=aa,file=/tmp/foo,if=none -drive id=bb,file=/tmp/foo,if=none -device
ide-hd,drive=aa -device ide-hd,drive=bb
qemu-system-x86_64: -device ide-hd,drive=bb: Can't create IDE unit 1, bus
supports only 1 units
qemu-system-x86_64: -device ide-hd,drive=bb: Device initialization failed.
qemu-system-x86_64: -device ide-hd,drive=bb: Device 'ide-hd' could not be
initialized
If a bus isn't specified for -device ide-hd, it just uses the first bus
it finds, not taking into account if that bus was already assigned for
another device. So users are forced to do -device ide-hd,bus=ide.0
-device ide-hd,bus=ide.1, etc.
This isn't specific to -device ahci, but it's worse there since there
isn't any -drive if=IDE or -hda convenience option, which both seem to
get the logic correct.
I know -device is the 'build it yourself' approach so I understand if
this is WONTFIX.
This is affects qemu.git as of today (8-31-2013)
