| # @report: for guest operations, report the error to the guest; for | |
| # jobs, cancel the job | |

| # or BLOCK_JOB_ERROR). The backup, mirror and commit block jobs | |
| # retry the failing request later and may still complete | |
| # successfully. The stream block job continues to stream and will | |

| # | |
| # @device: The device name or node-name of a root node whose writes | |
| # should be mirrored. | |
| # | |
| # @target: the id or node-name of the block device to mirror to. This | |
| # mustn't be attached to guest. | |
| # | |
| # @replaces: with sync=full graph node name to be replaced by the new | |
| # image when a whole image copy is done. This can be used to | |
| # repair broken Quorum files. By default, @device is replaced, | |
| # although implicitly created filters on it are kept. | |
| # | |
| # @speed: the maximum speed, in bytes per second | |
| # | |
| # @sync: what parts of the disk image should be copied to the | |
| # destination (all the disk, only the sectors allocated in the | |
| # topmost image, or only new I/O). | |
| # | |
| # @granularity: granularity of the dirty bitmap, default is 64K if the | |
| # image format doesn't have clusters, 4K if the clusters are | |
| # smaller than that, else the cluster size. Must be a power of 2 | |
| # between 512 and 64M | |
| # | |
| # @buf-size: maximum amount of data in flight from source to target | |
| # | |
| # @on-source-error: the action to take on an error on the source, | |
| # default 'report'. 'stop' and 'enospc' can only be used if the | |
| # block device supports io-status (see BlockInfo). | |
| # | |
| # @on-target-error: the action to take on an error on the target, | |
| # default 'report' (no limitations, since this applies to a | |
| # different block device than @device). | |
| # | |
| # @filter-node-name: the node name that should be assigned to the | |
| # filter driver that the mirror job inserts into the graph above | |
| # @device. If this option is not given, a node name is | |
| # autogenerated. (Since: 2.9) | |
| # | |
| # @copy-mode: when to copy data to the destination; defaults to | |
| # 'background' (Since: 3.0) | |
| # | |
| # @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 | |

| # | |
| # @auto-dismiss: When false, this job will wait in a CONCLUDED state | |
| # after it has completely ceased all work, and awaits | |

| # @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) | |
| # | |
| # @backing-mask-protocol: If true, replace any protocol mentioned in | |
| # the 'backing file format' with 'raw', rather than storing the | |
| # protocol name as the backing format. Can be used even when no | |
| # image header will be updated (default false; since 9.0). | |
| # | |
| # @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) | |

| # 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. | |

| # @BlockdevOptionsCbw: | |
| # | |
| # Driver specific block device options for the copy-before-write | |
| # driver, which does so called copy-before-write operations: when data | |
| # is written to the filter, the filter first reads corresponding | |
| # blocks from its file child and copies them to @target child. After | |
| # successfully copying, the write request is propagated to file child. | |
| # If copying fails, the original write request is failed too and no | |
| # data is written to file child. | |
| # | |
| # @target: The target for copy-before-write operations. | |
| # | |
| # @bitmap: If specified, copy-before-write filter will do | |
| # copy-before-write operations only for dirty regions of the | |
| # bitmap. Bitmap size must be equal to length of file and target | |
| # child of the filter. Note also, that bitmap is used only to | |
| # initialize internal bitmap of the process, so further | |
| # modifications (or removing) of specified bitmap doesn't | |
| # influence the filter. (Since 7.0) | |
| # | |
| # @on-cbw-error: Behavior on failure of copy-before-write operation. | |
| # Default is @break-guest-write. (Since 7.1) | |
| # | |
| # @cbw-timeout: Zero means no limit. Non-zero sets the timeout in | |
| # seconds for copy-before-write operation. When a timeout occurs, | |
| # the respective copy-before-write operation will fail, and the | |
| # @on-cbw-error parameter will decide how this failure is handled. | |
| # Default 0. (Since 7.1) | |
| # | |
| # @min-cluster-size: Minimum size of blocks used by copy-before-write | |
| # operations. Has to be a power of 2. No effect if smaller than | |
| # the maximum of the target's cluster size and 64 KiB. Default 0. | |
| # (Since 9.2) | |

| # @BlockdevOptions: | |
| # | |
| # Options for creating a block device. Many options are available for | |
| # all block devices, independent of the block driver: | |
| # | |
| # @driver: block driver name | |
| # | |
| # @node-name: the node name of the new node (Since 2.0). This option | |
| # is required on the top level of blockdev-add. Valid node names | |
| # start with an alphabetic character and may contain only | |
| # alphanumeric characters, '-', '.' and '_'. Their maximum length | |
| # is 31 characters. | |
| # | |
| # @discard: discard-related options (default: ignore) | |
| # | |
| # @cache: cache-related options | |
| # | |
| # @active: whether the block node should be activated (default: true). | |
| # Having inactive block nodes is useful primarily for migration because it | |
| # allows opening an image on the destination while the source is still | |
| # holding locks for it. (Since 10.0) | |
| # | |
| # @read-only: whether the block device should be read-only (default: | |
| # false). Note that some block drivers support only read-only | |
| # access, either generally or in certain configurations. In this | |
| # case, the default value does not work and the option must be | |
| # specified explicitly. | |
| # | |
| # @auto-read-only: if true and @read-only is false, QEMU may | |
| # automatically decide not to open the image read-write as | |
| # requested, but fall back to read-only instead (and switch | |
| # between the modes later), e.g. depending on whether the image | |
| # file is writable or whether a writing user is attached to the | |
| # node (default: false, since 3.1) | |
| # | |
| # @detect-zeroes: detect and optimize zero writes (Since 2.1) | |
| # (default: off) | |
| # | |
| # @force-share: force share all permission on added nodes. Requires | |
| # read-only=true. (Since 2.10) | |
| # | |
| # Since: 2.9 | |

| # or a particular driver does not support reopening then the command | |
| # will return an error. All devices in the list are reopened in one | |
| # transaction, so if one of them fails then the whole transaction is | |
| # cancelled. | |
| # | |
| # The command receives a list of block devices to reopen. For each | |
| # one of them, the top-level @node-name option (from BlockdevOptions) | |
| # must be specified and is used to select the block device to be | |
| # reopened. Other @node-name options must be either omitted or set to | |
| # the current name of the appropriate node. This command won't change | |
| # any node name and any attempt to do it will result in an error. | |
| # | |
| # In the case of options that refer to child nodes, the behavior of | |

| # 1) A set of options (BlockdevOptions): the child is reopened with | |
| # the specified set of options. | |
| # | |
| # 2) A reference to the current child: the child is reopened using | |
| # its existing set of options. | |
| # | |
| # 3) A reference to a different node: the current child is replaced | |
| # with the specified one. | |
| # | |
| # 4) NULL: the current child (if any) is detached. | |
| # | |
| # Options (1) and (2) are supported in all cases. Option (3) is | |
| # supported for @file and @backing, and option (4) for @backing only. | |
