This serial of patches does two things: merge some info code
in qemu-img, and add following interfaces:
1) qmp: query-image
2) qmp: query-snapshot
3) hmp: show 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
Note:
Last two patches need previous sent patches which extend hmp sub command, at:
