      qemu-img: Require larger zero areas for sparse handling · a22f123c
      由 Kevin Wolf 提交于 
      By default, require 4k of consecutive zero bytes for qemu-img to make the
output file sparse by not issuing a write request for the zeroed parts. Add an
-S option to allow users to tune this setting.

This helps to avoid situations where a lot of zero sectors and data sectors are
mixed and qemu-img tended to issue many tiny 512 byte writes.

      Copy snapshots out of QCOW2 disk · 51ef6727
      由 edison 提交于 
      In order to backup snapshots, created from QCOW2 iamge, we want to copy snapshots out of QCOW2 disk to a seperate storage.
The following patch adds a new option in "qemu-img": qemu-img convert -f qcow2 -O qcow2 -s snapshot_name src_img bck_img.
Right now, it only supports to copy the full snapshot, delta snapshot is on the way.

Changes from V1: all the comments from Kevin are addressed:
Add read-only checking
Fix coding style
Change the name from bdrv_snapshot_load to bdrv_snapshot_load_tmp

      Synch code, help and docs · d2c639d6
      由 blueswir1 提交于 
      Rearrange code, help printout and docs so that they are in the same
(hopefully more logical) order for easier maintenance.

Add help and docs for undocumented options.

Reformat slightly for more consistent help output.

Add comments to encourage better synchronization in the future.
