| # |
| # If top == base, that is an error. |
| # If top has no overlays on top of it, or if it is in use by a writer, |

| # |
| # If the base image is smaller than top, then the base image will be |
| # resized to be the same size as top. If top is smaller than the base |

| # @backing-file: The backing file string to write into the overlay |
| # image of 'top'. If 'top' does not have an overlay |
| # image, or if 'top' is in use by a writer, specifying |
| # a backing file string is an error. |
| # |
| # This filename is not validated. If a pathname string |
| # is such that it cannot be resolved by QEMU, that |
| # means that subsequent QMP or HMP commands must use |
| # node-names for the image in question, as filename |
| # lookup methods will fail. |
| # |
| # If not specified, QEMU will automatically determine |
| # the backing file string to use, or error out if |
| # there is no obvious choice. Care should be taken |
| # when specifying the string, to specify a valid |
| # filename or protocol. |
| # (Since 2.1) |

| # @block-stream: |
| # |
| # Copy data from a backing file into a block device. |
| # |
| # The block streaming operation is performed in the background until the entire |
| # backing file has been copied. This command returns immediately once streaming |
| # has started. The status of ongoing block streaming operations can be checked |
| # with query-block-jobs. The operation can be stopped before it has completed |
| # using the block-job-cancel command. |
| # |
| # The node that receives the data is called the top image, can be located in |
| # any part of the chain (but always above the base image; see below) and can be |
| # specified using its device or node name. Earlier qemu versions only allowed |
| # 'device' to name the top level node; presence of the 'base-node' parameter |
| # during introspection can be used as a witness of the enhanced semantics |
| # of 'device'. |
| # |
| # If a base file is specified then sectors are not copied from that base file and |
| # its backing chain. This can be used to stream a subset of the backing file |
| # chain instead of flattening the entire image. |
| # When streaming completes the image file will have the base file as its backing |
| # file, unless that node was changed while the job was running. In that case, |
| # base's parent's backing (or filtered, whichever exists) child (i.e., base at |
| # the beginning of the job) will be the new backing file. |
| # |
| # On successful completion the image file is updated to drop the backing file |
| # and the BLOCK_JOB_COMPLETED event is emitted. |
| # |
| # In case @device is a filter node, block-stream modifies the first non-filter |
| # overlay node below it to point to the new backing node instead of modifying |
| # @device itself. |
| # |
| # @job-id: identifier for the newly-created block job. If |
| # omitted, the device name will be used. (Since 2.7) |
| # |
| # @device: the device or node name of the top image |
| # |
| # @base: the common backing file name. |
| # It cannot be set if @base-node or @bottom is also set. |
| # |
| # @base-node: the node name of the backing file. |
| # It cannot be set if @base or @bottom is also set. (Since 2.8) |
| # |
| # @bottom: the last node in the chain that should be streamed into |
| # top. It cannot be set if @base or @base-node is also set. |
| # It cannot be filter node. (Since 6.0) |
| # |
| # @backing-file: The backing file string to write into the top |
| # image. This filename is not validated. |
| # |
| # If a pathname string is such that it cannot be |
| # resolved by QEMU, that means that subsequent QMP or |
| # HMP commands must use node-names for the image in |
| # question, as filename lookup methods will fail. |
| # |
| # If not specified, QEMU will automatically determine |
| # the backing file string to use, or error out if there |
| # is no obvious choice. Care should be taken when |
| # specifying the string, to specify a valid filename or |
| # protocol. |
| # (Since 2.1) |
| # |
| # @speed: the maximum speed, in bytes per second |
| # |
| # @on-error: the action to take on an error (default report). |
| # 'stop' and 'enospc' can only be used if the block device |
| # supports io-status (see BlockInfo). Since 1.3. |
| # |
| # @filter-node-name: the node name that should be assigned to the |
| # filter driver that the stream job inserts into the graph |
| # above @device. If this option is not given, a node name is |
| # autogenerated. (Since: 6.0) |
| # |
| # @auto-finalize: When false, this job will wait in a PENDING state after it has |
| # finished its work, waiting for @block-job-finalize before |
| # making any block graph changes. |
| # When true, this job will automatically |
| # perform its abort or commit actions. |
| # Defaults to true. (Since 3.1) |
| # |
| # @auto-dismiss: When false, this job will wait in a CONCLUDED state after it |
| # has completely ceased all work, and awaits @block-job-dismiss. |
| # When true, this job will automatically disappear from the query |
| # list without user intervention. |
| # Defaults to true. (Since 3.1) |
| # |
| # Returns: - Nothing on success. |
| # - If @device does not exist, DeviceNotFound. |
| # |
| # Since: 1.1 |
| # |
| # Example: |
| # |
| # -> { "execute": "block-stream", |
| # "arguments": { "device": "virtio0", |
| # "base": "/tmp/master.qcow2" } } |

| # This command returns immediately after marking the active background block |

| # The operation will cancel as soon as possible and then emit the |

| # |
| # Note that if you issue 'block-job-cancel' after 'drive-mirror' has indicated |
| # (via the event BLOCK_JOB_READY) that the source and destination are |
| # synchronized, then the event triggered by this command changes to |
| # BLOCK_JOB_COMPLETED, to indicate that the mirroring has ended and the |
| # destination now has a point-in-time copy tied to the time of the cancellation. |
| # |
| # For streaming, the image file retains its backing file unless the streaming |
| # operation happens to complete just as it is being cancelled. A new streaming |
| # operation can be started at a later time to finish copying all data from the |
