More than one byte could be locked by the QEMU instance, each byte of which

+
+Filter drivers
+~~~~~~~~~~~~~~
+
+QEMU supports several filter drivers, which don't store any data, but perform
+some additional tasks, hooking io requests.
+
+.. program:: filter-drivers
+.. option:: preallocate
+
+ The preallocate filter driver is intended to be inserted between format
+ and protocol nodes and preallocates some additional space
+ (expanding the protocol file) when writing past the file’s end. This can be
+ useful for file-systems with slow allocation.
+
+ Supported options:
+
+ .. program:: preallocate
+ .. option:: prealloc-align
+
+ On preallocation, align the file length to this value (in bytes), default 1M.
+
+ .. program:: preallocate
+ .. option:: prealloc-size
+
+ How much to preallocate (in bytes), default 128M.

+QEMU Storage Daemon
+===================
+
+Synopsis
+--------
+
+**qemu-storage-daemon** [options]
+
+Description
+-----------
+
+qemu-storage-daemon provides disk image functionality from QEMU, qemu-img, and
+qemu-nbd in a long-running process controlled via QMP commands without running
+a virtual machine. It can export disk images, run block job operations, and
+perform other disk-related operations. The daemon is controlled via a QMP
+monitor and initial configuration from the command-line.
+
+The daemon offers the following subset of QEMU features:
+
+* Block nodes
+* Block jobs
+* Block exports
+* Throttle groups
+* Character devices
+* Crypto and secrets
+* QMP
+* IOThreads
+
+Commands can be sent over a QEMU Monitor Protocol (QMP) connection. See the
+:manpage:`qemu-storage-daemon-qmp-ref(7)` manual page for a description of the
+commands.
+
+The daemon runs until it is stopped using the ``quit`` QMP command or
+SIGINT/SIGHUP/SIGTERM.
+
+**Warning:** Never modify images in use by a running virtual machine or any
+other process; this may destroy the image. Also, be aware that querying an
+image that is being modified by another process may encounter inconsistent
+state.
+
+Options
+-------
+
+.. program:: qemu-storage-daemon
+
+Standard options:
+
+.. option:: -h, --help
+
+ Display help and exit
+
+.. option:: -V, --version
+
+ Display version information and exit
+
+.. option:: -T, --trace [[enable=]PATTERN][,events=FILE][,file=FILE]
+
+ .. include:: ../qemu-option-trace.rst.inc
+
+.. option:: --blockdev BLOCKDEVDEF
+
+ is a block node definition. See the :manpage:`qemu(1)` manual page for a
+ description of block node properties and the :manpage:`qemu-block-drivers(7)`
+ manual page for a description of driver-specific parameters.
+
+.. option:: --chardev CHARDEVDEF
+
+ is a character device definition. See the :manpage:`qemu(1)` manual page for
+ a description of character device properties. A common character device
+ definition configures a UNIX domain socket::
+
+ --chardev socket,id=char1,path=/tmp/qmp.sock,server,nowait
+
+.. option:: --export [type=]nbd,id=<id>,node-name=<node-name>[,name=<export-name>][,writable=on|off][,bitmap=<name>]
+ --export [type=]vhost-user-blk,id=<id>,node-name=<node-name>,addr.type=unix,addr.path=<socket-path>[,writable=on|off][,logical-block-size=<block-size>][,num-queues=<num-queues>]
+ --export [type=]vhost-user-blk,id=<id>,node-name=<node-name>,addr.type=fd,addr.str=<fd>[,writable=on|off][,logical-block-size=<block-size>][,num-queues=<num-queues>]
+
+ is a block export definition. ``node-name`` is the block node that should be
+ exported. ``writable`` determines whether or not the export allows write
+ requests for modifying data (the default is off).
+
+ The ``nbd`` export type requires ``--nbd-server`` (see below). ``name`` is
+ the NBD export name. ``bitmap`` is the name of a dirty bitmap reachable from
+ the block node, so the NBD client can use NBD_OPT_SET_META_CONTEXT with the
+ metadata context name "qemu:dirty-bitmap:BITMAP" to inspect the bitmap.
+
+ The ``vhost-user-blk`` export type takes a vhost-user socket address on which
+ it accept incoming connections. Both
+ ``addr.type=unix,addr.path=<socket-path>`` for UNIX domain sockets and
+ ``addr.type=fd,addr.str=<fd>`` for file descriptor passing are supported.
+ ``logical-block-size`` sets the logical block size in bytes (the default is
+ 512). ``num-queues`` sets the number of virtqueues (the default is 1).
+
+.. option:: --monitor MONITORDEF
+
+ is a QMP monitor definition. See the :manpage:`qemu(1)` manual page for
+ a description of QMP monitor properties. A common QMP monitor definition
+ configures a monitor on character device ``char1``::
+
+ --monitor chardev=char1
+
+.. option:: --nbd-server addr.type=inet,addr.host=<host>,addr.port=<port>[,tls-creds=<id>][,tls-authz=<id>][,max-connections=<n>]
+ --nbd-server addr.type=unix,addr.path=<path>[,tls-creds=<id>][,tls-authz=<id>][,max-connections=<n>]
+
+ is a server for NBD exports. Both TCP and UNIX domain sockets are supported.
+ TLS encryption can be configured using ``--object`` tls-creds-* and authz-*
+ secrets (see below).
+
+ To configure an NBD server on UNIX domain socket path ``/tmp/nbd.sock``::
+
+ --nbd-server addr.type=unix,addr.path=/tmp/nbd.sock
+
+.. option:: --object help
+ --object <type>,help
+ --object <type>[,<property>=<value>...]
+
+ is a QEMU user creatable object definition. List object types with ``help``.
+ List object properties with ``<type>,help``. See the :manpage:`qemu(1)`
+ manual page for a description of the object properties.
+
+Examples
+--------
+Launch the daemon with QMP monitor socket ``qmp.sock`` so clients can execute
+QMP commands::
+
+ $ qemu-storage-daemon \
+ --chardev socket,path=qmp.sock,server,nowait,id=char1 \
+ --monitor chardev=char1
+
+Export raw image file ``disk.img`` over NBD UNIX domain socket ``nbd.sock``::
+
+ $ qemu-storage-daemon \
+ --blockdev driver=file,node-name=disk,filename=disk.img \
+ --nbd-server addr.type=unix,addr.path=nbd.sock \
+ --export type=nbd,id=export,node-name=disk,writable=on
+
+Export a qcow2 image file ``disk.qcow2`` as a vhosts-user-blk device over UNIX
+domain socket ``vhost-user-blk.sock``::
+
+ $ qemu-storage-daemon \
+ --blockdev driver=file,node-name=file,filename=disk.qcow2 \
+ --blockdev driver=qcow2,node-name=qcow2,file=file \
+ --export type=vhost-user-blk,id=export,addr.type=unix,addr.path=vhost-user-blk.sock,node-name=qcow2

+# Test drive-mirror with quorum

+# The goal of this test is to check how the quorum driver reports
+# regions that are known to read as zeroes (BDRV_BLOCK_ZERO). The idea
+# is that drive-mirror will try the efficient representation of zeroes
+# in the destination image instead of writing actual zeroes.
