Description Zeeshan Ali 2011-11-14 12:37:21 EST
Description of problem:

Floppy support in qemu is broken and no guest OS (windows or linux) is able to read from floppy images when floppy image path is passed to qemu using '-fda' option rather than '-drive' (i-e always reproducible when using libvirtd). Since the issue has already been fixed in qemu git master by Kevin Wolf, I don't see the need to provide more details as the solution is simply to merge block devices/floppy related patches from Kevin.

Version-Release number of selected component (if applicable): 0.15.1

How reproducible: Always
Comment 1 Kevin Wolf 2011-11-14 12:57:49 EST
The relevant upstream commit IDs are 34d4260e (most definitely required), a18e67f5 and acae6f1c (probably both not required in 0.15).
Comment 2 Justin M. Forbes 2011-11-15 10:54:00 EST
This will make the next update.  Thanks for the report, and thanks for the upstream commit references Kevin.

floppy fixes for fedora qemu

Here is the patch I applied locally to the f16 qemu package to get working floppy devices. The 34d4260e184 commit needed some (trivial) rediffing in hw/pc_piix.c
I tested that floppy support was fixed by dowloading a DOS floppy image used for bios flashing and starting it with 
qemu-kvm -drive file=DRDFLASH.IMG,if=none,id=fdc,format=raw -global isa-fdc.driveA=fdc
With the current fedora package, this fails with "no bootable devices found", with a package built with the attached patch, I get to a dos prompt

Justin, any word on this?
Comment 5 Christophe Fergeau 2012-01-25 04:31:13 EST
I've uploaded a qemu 0.15 package with this patch to if that can help with testing.
