This serial of patches does two things: merge some info code
in qemu-img, and add following interfaces:
1) qmp: query-images
2) qmp: query-snapshots
3) hmp: show internal snapshot info on a single block device
These patches follows the rule that use qmp to retieve information,
hmp layer just do a translation from qmp object it got, so almost
every hmp interface may have a correlated qmp interface.
To make code graceful, snapshot retrieving code in qemu and qemu-img
are merged into block.c, and some function name was adjusted to make it
tips better. Now it works as:
qemu qemu-img
dump_monitor dump_stdout
|--------------|
|
qmp
|
block
This summary does not explain how the new commands relate to query-block
or why they are necessary.
It is also useful to include QMP examples or the QMP docs in the cover
letter so reviewers know what you are trying to achieve.
