[Qemu-devel] [PATCH v7 for 2.0 0/4] qemu-img: add preallocation=full

[Hu Tao]

This series implements full image preallocation to create a non-sparse
image file at creation time, both for raw and qcow2 format. The purpose
is to avoid performance deterioration of the guest cause by sparse image.

v7:
  - fix qemu-iotests fail case 082.


Hu Tao (4):
  qapi: introduce PreallocMode and a new PreallocMode full.
  raw, qcow2: don't convert file size to sector size
  raw-posix: Add full image preallocation option
  qcow2: Add full image preallocation option
