Hi, Latest qemu-img (maybe from 0.11.0-rc0 or later?) changes default unit of size as bytes, it was kilo-bytes so far. (see http://www.mail-archive.com/kvm@vger.kernel.org/msg19183.html) This patch addresses this incompatibility by adding postfix 'K'. This fix is able to keep backward compatibility for old qemu as well, and also even if qemu-img falls back old style or any, this explicit specifying should work well.
