Public bug reported:
The snapshot mode is not working if you use raw format for image instead
of qcow2. Create a raw disk image by running "dd of=xxx.img bs=1 count=0
seek=8G". Then run "qemu -snapshot xxx.img". In monitor console run
"info block". There should be qcow2 temporary image backed by the raw
image. Now run "commit ide0-hd0" and after that again "info block". You
should see now that there is no more image, so any operations on it will
fail form now on. This is for latest HEAD in git.

git bisect points to
commit c33491978c5c4c746cc0272d5f2df50aa14d1f02
Author: Kevin Wolf <kwolf@redhat.com>
Date: Thu May 6 16:34:56 2010 +0200
block: Fix bdrv_commit
When reopening the image, don't guess the driver, but use the same driver as
was used before. This is important if the format=... option was used for that
image.
