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.

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.
