Subject: [PATCH 2/6] ioemu: Use the image format sent by blktapctrl
Currently the blktap backend in ioemu lets qemu guess which format an
image is in. This was a security problem and the blktap backend
doesn't work any more since this was fixed in qemu.
This patch changes ioemu to respect the format it gets from blktapctrl.
