Title:
Can't(?) disable default floppy drive any more in qemu 6.0
Status in QEMU:
Expired
Bug description:
There's a documented change in qemu 6.0:
https://qemu-project.gitlab.io/qemu/system/removed-features.html
#floppy-controllers-drive-properties-removed-in-6-0
where you can't configure floppy controller device properties with
-global any more. However, there's a thing you could do with the old
parameter which I can't figure out a way to do with the documented
replacement. openQA passed exactly this argument:
-global isa-fdc.driveA=
and that has the effect of removing/disabling the default floppy
drive/controller. If you just run `qemu-system-i686` (no other args)
you'll see the VM briefly try to boot from a floppy drive; if you run
`qemu-system-i686 -global isa-fdc.driveA=` (with an earlier version of
qemu, obviously) you'll see it does not do so.
I can't see a way to do this with `-device floppy`. Going by the docs,
the equivalent should be:
-device floppy,unit=0,drive=
but that does not seem to have the same effect. If you run `qemu-
system-i686 -device floppy,unit=0,drive=`, it still tries to boot from
a floppy drive.
I see there's a -nodefaults option that disables *all* default
devices, but I don't think that's what we want here either. We might
want the other default devices, we just don't want the floppy drive.
