Hi folks:
We've captured a regression with floppy disk on recent qemu (and
qemu-kvm, after a code merge). We bisected it to be caused by:
commit 212ec7baa28cc9d819234fed1541fc1423cfe3d8
Author: Richard Henderson<rth@xxxxxxxxxxx>

Since this commit, the guest doesn't see a floppy disk attached to it
anymore, blocking kvm autotest ability to install windows guests
automatically. This is a big deal for kvm autotest (ruins our automated
regression jobs), so please take a look at it.
Can you please try again with the latest block branch? I think there is
a patch queued that will fix it.
Kevin, I did try with HEAD of your repo:
git://repo.or.cz/qemu/kevin.git
[lmr@freedom qemu-kwolf]$ git branch -r
origin/HEAD -> origin/master
origin/blkqueue
origin/blkqueue-v1
origin/block
origin/coroutine
origin/coroutine-block
origin/coroutine-devel
origin/devel
origin/ehci
origin/for-anthony
origin/for-stable-0.14
origin/inplace-conversion
origin/master
With this repo, master branch, the problem persists. With the block
branch, the problem persists.
Now, with the blkqueue branch the problem is resolved. Cleber had the
same results booting a FreeDOS floppy. So the fix is indeed in blkqueue.
Oh, you might want to check the blkqueue branch, it does have quite a
bunch of set but unused variables, which will cause compilation errors
unless --disable-werror is passed to the configure script.
Please merge the fixes with qemu master as soon as you can, we are
probably leave windows installs from the upstream daily jobs until the
fixes get to master.
Thanks,
Lucas
