* remotes/kevin/tags/for-upstream:
  block/vpc: Use sizeof() instead of HEADER_SIZE for footer size
  block/vpc: Pass footer buffers as VHDFooter * instead of uint8_t *
  block/vpc: Pad VHDFooter, replace uint8_t[] buffers
  block/vpc: Use sizeof() instead of 1024 for dynamic header size
  block/vpc: Pad VHDDynDiskHeader, replace uint8_t[] buffers
  block/vpc: Make vpc_checksum() take void *
  block/vpc: Don't abuse the footer buffer for dynamic header
  block/vpc: Don't abuse the footer buffer as BAT sector buffer
  block/vpc: Make vpc_open() read the full dynamic header
  iotests:172: use _filter_qom_path
  iotests: make _filter_qom_path more strict
  MAINTAINERS: add Kevin Wolf as storage daemon maintainer
  docs: add qemu-storage-daemon(1) man page

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
