to support the VDI format in QEMU.

VDI is the native format used by Innotek / SUN VirtualBox.

vmdk: Fix backing file handling

Instead of storing the backing file in its own BlockDriverState, VMDK uses the
BlockDriverState of the raw image file it opened. This is wrong and breaks
functions that access the backing file or protocols. This fix replaces all...

raw-posix: Handle errors in raw_create

In qemu-iotests, some large images are created using qemu-img.

Without checks for errors, qemu-img will just create an

With the patch, failures during image creation are detected...

image file that is constructed from the VM state offset and an offset...

qcow2: Fix L1 table memory allocation

Contrary to what one could expect, the size of L1 tables is not cluster
aligned. So as we're writing whole sectors now instead of single entries,
we need to ensure that the L1 table in memory is large enough; otherwise...
