-@c man begin DESCRIPTION
-
-Export a QEMU disk image using the NBD protocol.
-
-@c man end
-
-@c man begin OPTIONS
-@var{filename} is a disk image filename.
-
-@var{dev} is an NBD device.
-
-@table @option
-@item -p, --port=@var{port}
-The TCP port to listen on (default @samp{10809})
-@item -o, --offset=@var{offset}
-The offset into the image
-@item -b, --bind=@var{iface}
-The interface to bind to (default @samp{0.0.0.0})
-@item -k, --socket=@var{path}
-Use a unix socket with path @var{path}
-@item -f, --format=@var{fmt}
-Force the use of the block driver for format @var{fmt} instead of
-auto-detecting
-@item -r, --read-only
-Export the disk as read-only
-@item -P, --partition=@var{num}
-Only expose partition @var{num}
-@item -s, --snapshot
-Use @var{filename} as an external snapshot, create a temporary
-file with backing_file=@var{filename}, redirect the write to
-the temporary one
-@item -l, --load-snapshot=@var{snapshot_param}
-Load an internal snapshot inside @var{filename} and export it
-as an read-only device, @var{snapshot_param} format is
-'snapshot.id=[ID],snapshot.name=[NAME]' or '[ID_OR_NAME]'
-@item -n, --nocache
-@itemx --cache=@var{cache}
-The cache mode to be used with the file.  See the documentation of
-the emulator's @code{-drive cache=...} option for allowed values.
-@item --aio=@var{aio}
-Set the asynchronous I/O mode between @samp{threads} (the default)
-and @samp{native} (Linux only).
-@item --discard=@var{discard}
-Control whether @dfn{discard} (also known as @dfn{trim} or @dfn{unmap})
-requests are ignored or passed to the filesystem.  @var{discard} is one of
-@samp{ignore} (or @samp{off}), @samp{unmap} (or @samp{on}).  The default is
-@samp{ignore}.
-@item --detect-zeroes=@var{detect-zeroes}
-Control the automatic conversion of plain zero writes by the OS to
-driver-specific optimized zero write commands.  @var{detect-zeroes} is one of
-@samp{off}, @samp{on} or @samp{unmap}.  @samp{unmap}
-converts a zero write to an unmap operation and can only be used if
-@var{discard} is set to @samp{unmap}.  The default is @samp{off}.
-@item -c, --connect=@var{dev}
-Connect @var{filename} to NBD device @var{dev}
-@item -d, --disconnect
-Disconnect the device @var{dev}
-@item -e, --shared=@var{num}
-Allow up to @var{num} clients to share the device (default @samp{1})
-@item -t, --persistent
-Don't exit on the last connection
-@item -v, --verbose
-Display extra debugging information
-@item -h, --help
-Display this help and exit
-@item -V, --version
-Display version information and exit
