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.
