Subject: [Qemu-devel] [PATCH v6 0/4] qemu-img: add preallocation=full
Date: Fri, 28 Feb 2014 10:29:29 +0800 [thread overview]
Message-ID: <cover.1393554457.git.hutao@cn.fujitsu.com> (raw)
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
