None of the other qemu-img subcommands uses writethrough, and there's no reason why snapshot should be special. Signed-off-by: NKevin Wolf <kwolf@redhat.com> Reviewed-by: NStefan Hajnoczi <stefanha@linux.vnet.ibm.com>

This patch re-factors img_create() moving the code doing the actual work into block.c where it can be shared with QEMU.

This cleans up the handling of image size in img_create() by parsing the value early, and then only setting it once if a value has been added as the last argument to the command line.

This consolidates the printing of block driver options in print_block_option_help() which is called from both img_create() and img_convert(). This allows for the "?" detection to be done just after the parsing of options and the filename, instead of half way down the codepath of these functions.

The old -B option caused a backing file to be used for the converted image and to avoid copying clusters from the old backing file. When replaced with -obacking_file, qemu-img convert does assign the backing file to the new image, but it doesn't realize that it should avoid copying clusters from the backing file. This patch checks the -o options for a backing_file and applies the same logic as for -B in this case. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

In order to backup snapshots, created from QCOW2 iamge, we want to copy snapshots out of QCOW2 disk to a seperate storage. The following patch adds a new option in "qemu-img": qemu-img convert -f qcow2 -O qcow2 -s snapshot_name src_img bck_img. Right now, it only supports to copy the full snapshot, delta snapshot is on the way.

This patch removes exit(1) from error(), and properly releases resources such as a block driver and an allocated memory. For testing the Sheepdog block driver with qemu-iotests, it is necessary to call bdrv_delete() before the program exits. Because the driver releases the lock of VM images in the close handler.

qemu-img rebase must always give clusters in the COW file priority over those in the backing file. As it failed to use number of non-allocated clusters but assumed the maximum, it was possible that allocated clusters were taken from the backing file instead, leading to a corrupted output image.

Several commands have code to create a BlockDriverState and open a file. The bdrv_new_open() function can be used to perform these steps. This patch converts the qemu-img commands to actually use bdrv_new_open(). Replaced the bdrv_new_open() 'readonly' argument with bdrv_open()-style flags to support generic flags like BDRV_O_NO_BACKING.

The default stack size of PE is 1MB on win32 and IO_BUF_SIZE in img_convert() & img_rebase() is 2MB, so qemu-img will crash when doing "convert" & "rebase" on win32. Although we can improve the stack size of PE to resolve it, I think we should avoid using the huge stack variables.
