[Qemu-devel] [PATCH 0/4] Make qemu-img create options generic

[Kevin Wolf <kwolf@redhat.com>]

Currently, qemu-img and the bdrv_create() interface need to carry parameters
for every single option that is used by at least one file format. We already
have a few of such format specific options (encryption for qcow2, version 6
header for VMDK, backing file for some formats) and there are more to come
(like qcow cluster size).

This patch series changes this into a more generic approach: All block drivers
contain a data structure which describes all options this driver recognizes.
qemu-img can use this structure then instead of hard-coding every single
option. An -o option is introduced for these parameteres, the format is the
usual comma separated name=value style like in -drive.

Kevin Wolf (4):
  Create qemu-option.h
  Convert all block drivers to new bdrv_create
  Convert qemu-img create to new bdrv_create
  Convert qemu-img convert to new bdrv_create
