2012-10-24qemu-img rebase: use empty string to rebase without backing fileAlex Bligh1-1/+3
This patch allows an empty filename to be passed as the new base image name for qemu-img rebase to mean base the image on no backing file (i.e. independent of any backing file). According to Eric Blake, qemu-img rebase already supports this when '-u' is used; this adds support when -u is not used.

2012-08-17Documentation: Warn against qemu-img on active imageKevin Wolf1-0/+10
People have repeatedly expected that you can do things like snapshotting an image with qemu-img while a qemu instance is running. Maybe we need to consider locking the files while they are in use, but having a warning in the qemu-img manpage is doable for 1.2 and can't hurt anyway. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-06-15qemu-img: document qed format on qemu-img man pageStefan Hajnoczi1-0/+23

2012-06-15qemu-img check -r for repairing imagesKevin Wolf1-1/+6
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: Kevin Wolf <kwolf@redhat.com>

2011-08-29qemu-img: Require larger zero areas for sparse handlingKevin Wolf1-1/+6
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: Kevin Wolf <kwolf@redhat.com>

2010-10-22Copy snapshots out of QCOW2 diskedison1-2/+2
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.

2009-11-09Documentation: Don't mention old qemu-img optionsKevin Wolf1-21/+17
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.

2009-03-28qemu-img: adding a "-F base_fmt" option to "qemu-img create -b" (Uri Lublin)aliguori1-1/+3
If the user specifies the backing file format, then when opening the backing file, there is no need to probe the (backing file) image to figure out its format. This follows my previous patches implementing bdrv_create2 which keeps (for qcow2 only) the backing file format as a qcow2-extension Suggested by Daniel P. Berrange.
