* Copy snapshots out of QCOW2 diskedison2010-10-221-2/+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. 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: Disheng Su <edison@cloud.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
* qemu-img: Add 'resize' command to grow/shrink disk imagesStefan Hajnoczi2010-05-031-0/+12
| | | | | | | | | This patch adds a 'resize' command to grow/shrink disk images. This allows changing the size of disk images without copying to a new image file. Currently only raw files support resize. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
* Documentation: Add options to image format descriptionsKevin Wolf2009-11-091-1/+45
| | | | | | | | Explain the existing format specific options that can be used with qemu-img create/convert -o ... Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* Documentation: Don't mention old qemu-img optionsKevin Wolf2009-11-091-21/+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.

* Documentation: Move image format descriptions to own sectionKevin Wolf2009-11-091-37/+41
| | | | | | | | | The description of the image formats is too long to be a subitem of a parameter description. It will become even longer when we include the options provided by the respective format. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* add host_device format description to qemu-img manpageAdrian Bridgett2009-10-061-0/+6
| | | | | | | | | | Converting files using "qemu-img convert" onto logical volumes (or any block device) you need to use the currently undocumented "host_device" format. This patch adds the required documentation to the manpage.

* Add new block driver for the VDI format (only aio supported)Stefan Weil2009-08-101-0/+2
| | | | | | | | | | | | | | | | | | | | This is a new block driver written from scratch to support the VDI format in QEMU. VDI is the native format used by Innotek / SUN VirtualBox. Latest changes: * stripped down version (code for synchronous operations and experimental code removed) * don't open VDI snapshot images (with uuid_link or uuid_parent) * modified vdi_aio_cancel Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Message-Id:
* Use hxtool for qemu-img command listStuart Brady2009-06-071-7/+2
| | | | | | | | | | Use hxtool to generate the 'command syntax' section of qemu-img's help message, and the corresponding section of the texinfo documentation. This has the side-effect of adding 'check' to this list of commands in the texinfo documentation. Signed-off-by: Stuart Brady <stuart.brady@gmail.com>
* Document changes in qemu-img interfaceKevin Wolf2009-06-061-14/+18
| | | | | | | | Update the documentation to reflect the introduction of format specific options with -o. Don't advertise -e or -6 any more, they exist only for compatibility reasons and can be replaced by the corresponding -o options. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
* qemu-img: adding a "-F base_fmt" option to "qemu-img create -b" (Uri Lublin)aliguori2009-03-281-1/+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.

* Synch code, help and docsblueswir12009-01-241-1/+25
| | | | | | | | | | | | | | 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. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6432 c046a42c-6fe2-441c-8c8c-71466251a162
