[Qemu-devel] [PATCH v6 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.

v6:
  - add `Since 2.0' to PreallocMode 
  - apply total_size change to raw-win32.c as well

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
