This patch allows using 'qemu-img $subcmd -o help' for the create, convert and amend subcommands, without specifying the previously required filename arguments. Note that it's still allowed and meaningful to specify a filename: An invocation like 'qemu-img create -o help sheepdog:foo' will also display options that are provided by the Sheepdog driver.

we currently do not check if a sector is allocated during convert. This means if a sector is unallocated that we allocate a bounce buffer of zeroes, find out its zero later and do not write it in the best case. In the worst case this can lead to reading blocks from a raw device (like iSCSI) altough we could easily know via get_block_status that they are zero and simply skip them. This patch also fixes the progress output not being at 100% after a successful conversion.

This patch moves ret assignment after reporting original error. We were lucky to pass qemu-iotests 048 (qemu-img compare case) but when I tried to run with TEST_DIR=/tmp (tmpfs), it fails with a "wrong" mismatch offset. This fixes two bugs. In the first if branch, setting ret to 1 before using it makes dead code in the next line: pnum is never added to mismatch offset even if ret was 0. In the other if branch, currently the output error is always -4: strerror(-4) -> Unknown error -4 Added regression test in case 048.

Snapshot creation actually already distinguish id and name since it take a structured parameter *sn, but delete can't. Later an accurate delete is needed in qmp_transaction abort and blockdev-snapshot-delete-sync, so change its prototype. Also *errp is added to tip error, but return value is kepted to let caller check what kind of error happens. Existing caller for it are savevm, delvm and qemu-img, they are not impacted by introducing a new function bdrv_snapshot_delete_by_id_or_name(), which check the return value and do the operation again. Before this patch: For qcow2, it search id first then name to find the one to delete. For rbd, it search name. For sheepdog, it does nothing. After this patch: For qcow2, logic is the same by call it twice in caller. For rbd, it always fails in delete with id, but still search for name in second try, no change to user. Some code for *errp is based on Pavel's patch. Signed-off-by: NWenchao Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: NPavel Hrdina <phrdina@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

qemu-img convert can assume "that sectors which are unallocated in the input image are present in both the output's and input's base images". However it is only doing this if the output image returns true for bdrv_has_zero_init(). Testing bdrv_has_zero_init() does not make much sense if the output image is copy-on-write, because a copy-on-write image is never initialized to zero (it is initialized to the content of the backing file). There is nothing here that makes has_zero_init images special. The input and output must be equal for the operation to make sense, and that's it.

One of the major reasons for doing something new for -blockdev and blockdev-add was that the old block layer code parses filenames instead of just taking them literally.
