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.
v5:
- fix wrong calculation of qcow2 metadata size in v4
- remove raw_preallocate2()
- better error out path in raw_create()
- fix coding style
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
