The QED block driver already provides the functionality to not only detect inconsistencies in images, but also fix them. However, this functionality cannot be manually invoked with qemu-img, but the check happens only automatically during bdrv_open(). This adds a -r switch to qemu-img check that allows manual invocation of an image repair. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

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. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

qemu-img currently writes disk images using writeback and filling up the cache buffers which are then flushed by the kernel preventing other processes from accessing the storage. This is particularly bad in cluster environments where time-based algorithms might be in place and accessing the storage within certain timeouts is critical. This patch adds the option to choose a cache method when writing disk images. Signed-off-by: NFederico Simoncelli <fsimonce@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

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 Signed-off-by: NDisheng Su <edison@cloud.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

This adds a rebase subcommand to qemu-img which allows to change the backing file of an image. In default mode, both the current and the new backing file need to exist, and after the rebase, the COW image is guaranteed to have the same guest visible content as before. To achieve this, old and new backing file are compared and, if necessary, data is copied from the old backing file into the COW image. With -u an unsafe mode is enabled that doesn't require the backing files to exist. It merely changes the backing file reference in the COW image. This is useful for renaming or moving the backing file. The user is responsible to make sure that the new backing file has no changes compared to the old one, or corruption may occur.

The old options are still supported for compatibility, but they are inconsistent (for example create -b vs. convert -B for backing files) and incomplete (-F only exists for create) which tends to confuse people. Remove all references to the old options from the documentation to guide users to the more consistent -o options.
