[Qemu-devel] [PATCH v2 00/12] covert savevm, loadvm and delvm into qapi |

I'm sending patches for all commands in one patch series because the
savevm command depends on delvm command.
This patch series introduces new design of these commands:
* QMP vm-snapshot-save:
- { 'command': 'vm-snapshot-save',
'data': { 'name': 'str' },
'returns': 'SnapshotInfo' }
- vm-snapshot-save returns an error if there is an existing snapshot with
the same name
- you cannot provide an id for a new snapshot
- all information about created snapshot will be returned
* QMP vm-snapshot-load
- { 'command': 'vm-snapshot-load',
'data': { '*name': 'str', '*id': 'str' },
'returns': 'SnapshotInfo' }
- one of the name or id must be provided
- if both are provided they will match only the snapshot with the same name
and id
- returns SnapshotInfo only if the snapshot exists.
* QMP vm-snapshot-delete:
- { 'command': 'vm-snapshot-delete',
'data': { '*name': 'str', '*id': 'str' },
'returns': 'SnapshotInfo' }
- same rules as vm-snapshot-load
* HMP savevm:
- args_type = "force:-f,name:s?",
- if the name is not provided the HMP command will generates new one for QMP
command
- if there is already a snapshot with provided or generated name it will
fails
- there will be an optional -f parameter to force saving requested snapshot
and it will internally use vm-snapshot-delete and then vm-snapshot-save
- all information about created snapshot will be printed
* HMP loadvm:
- args_type = "id:-i,name:s",
- follow almost the same behavior as the QMP command (QMP command has two
parameters but HMP command has one parameter with flag to switch between
name and id)
- it load snapshot that match the provided name
- if an id flag is provided, it load snapshot that match the name parameter
as an id of snapshot
* HMP delvm:
- args_type = "id:-i,name:s"
- same rules as loadvm
changes from v1:
- patch for updating bdrv_snapshot_goto and bdrv_snapshot_list is split
into two patches
- fixes typos and grammar
- vm-snapshot-delete and vm-snapshot-load now returns an error also if
snapshot for delete or load not exists
- all error messages starts with uppercase and are without trailing dot
- updated error messages recording to comments
