We bisected it to be caused by: commit 212ec7baa28cc9d819234fed1541fc1423cfe3d8 Author: Richard Henderson<address@hidden> Date: Mon Aug 15 15:08:45 2011 -0700 fdc: Convert to isa_register_portio_list Signed-off-by: Richard Henderson<address@hidden> Signed-off-by: Avi Kivity<address@hidden> 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 address@hidden 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/masterWith 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
