2009-06-07Use hxtool for qemu-img command listStuart Brady
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>
2009-06-06Document changes in qemu-img interfaceKevin Wolf
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>
2009-06-06qemu-img: Print available options with -o ?Kevin Wolf
This patch adds a small help text to each of the options in the block drivers which can be displayed by using qemu-img create -f fmt -o ? Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2009-05-22Convert qemu-img convert to new bdrv_createKevin Wolf
This is part two of the qemu-img conversion. This really works the same as the previous conversion of qemu-img create: It introduces a new -o option for the generic approach and adds the old-style options to this option set.

2009-05-22Convert qemu-img create to new bdrv_createKevin Wolf
This patch changes qemu-img to actually use the new bdrv_create interface. It translates the old-style qemu-img options which have been bdrv_create2 parameters or flags so far to option structures. As the generic approach, it introduces an -o option which accepts any parameter the driver knows. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-22Convert all block drivers to new bdrv_createKevin Wolf
Now we can make use of the newly introduced option structures. Instead of having bdrv_create carry more and more parameters (which are format specific in most cases), just pass a option structure as defined by the driver itself. bdrv_create2() contains an emulation of the old interface to simplify the transition.

2009-04-15block-vpc: Don't silently create smaller image than requestedaurel32
The algorithm from the VHD specification for CHS calculation silently limits images to 127 GB which may confuse a user who requested a larger image. Better output an error message and abort.

2009-04-05Add host_device support to qemu-img. (Nolan Leake)aliguori
This patch allows the use a host_device as the destination for "qemu-img convert". I added a ->bdrv_create function host_device. It merely verifies that the device exists and is large enough. A check is needed in the qemu-img convert loop to ensure that we write out all 0 sectors to the host_device. Otherwise they end up with stale garbage where all zero sectors were expected. I also made the check against bdrv_is_allocated enabled for everything _except_ host devices, since there is no point in making the block backend write a bunch of zeros just so that we can memcmp them immediately afterwards. Host devices can't benefit from this because there is no way to differentiate between a sector being unallocated because it was never written, or because it was written with all zeros and then made a trip through qemu-img convert. Finally, there is an unrelated fix for a typo in the error message printed if the destination device does not support ->bdrv_create.

2009-03-28qemu-img: adding a "-F base_fmt" option to "qemu-img create -b" (Uri Lublin)aliguori
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.
