+@c man begin SYNOPSIS
+usage: qemu-ga [OPTIONS]
+@c man end
+@end example
+
+@c man begin DESCRIPTION
+
+The QEMU Guest Agent is a daemon intended to be run within virtual
+machines. It allows the hypervisor host to perform various operations
+in the guest, such as:
+
+@itemize
+@item
+get information from the guest
+@item
+set the guest's system time
+@item
+read/write a file
+@item
+sync and freeze the filesystems
+@item
+suspend the guest
+@item
+reconfigure guest local processors
+@item
+set user's password
+@item
+...
+@end itemize
+
+qemu-ga will read a system configuration file on startup (located at
+q@file{/etc/qemu/qemu-ga.conf} by default), then parse remaining
+configuration options on the command line. For the same key, the last
+option wins, but the lists accumulate (see below for configuration
+file format).
+
+@c man end
+
+@c man begin OPTIONS
+@table @option
+@item -m, --method=@var{method}
+ Transport method: one of @samp{unix-listen}, @samp{virtio-serial}, or
+ @samp{isa-serial} (@samp{virtio-serial} is the default).
+
+@item -p, --path=@var{path}
+ Device/socket path (the default for virtio-serial is
+ @samp{/dev/virtio-ports/org.qemu.guest_agent.0},
+ the default for isa-serial is @samp{/dev/ttyS0})
+
+@item -l, --logfile=@var{path}
+ Set log file path (default is stderr).
+
+@item -f, --pidfile=@var{path}
+ Specify pid file (default is @samp{/var/run/qemu-ga.pid}).
+
+@item -F, --fsfreeze-hook=@var{path}
+ Enable fsfreeze hook. Accepts an optional argument that specifies
+ script to run on freeze/thaw. Script will be called with
+ 'freeze'/'thaw' arguments accordingly (default is
+ @samp{/etc/qemu/fsfreeze-hook}). If using -F with an argument, do
+ not follow -F with a space (for example:
+ @samp{-F/var/run/fsfreezehook.sh}).
+
+@item -t, --statedir=@var{path}
+ Specify the directory to store state information (absolute paths only,
+ default is @samp{/var/run}).
+
+@item -v, --verbose
+ Log extra debugging information.
+
+@item -V, --version
+ Print version information and exit.
+
+@item -d, --daemon
+ Daemonize after startup (detach from terminal).
+
+@item -b, --blacklist=@var{list}
+ Comma-separated list of RPCs to disable (no spaces, @samp{?} to list
+ available RPCs).
+
+@item -D, --dump-conf
+ Dump the configuration in a format compatible with @file{qemu-ga.conf}
+ and exit.
+
+@item -h, --help
+ Display this help and exit.
+@end table
+
+@c man end
+
+@c man begin FILES
+
+The syntax of the @file{qemu-ga.conf} configuration file follows the
+Desktop Entry Specification, here is a quick summary: it consists of
+groups of key-value pairs, interspersed with comments.
+
+@example
+# qemu-ga configuration sample
+[general]
+daemonize = 0
+pidfile = /var/run/qemu-ga.pid
+verbose = 0
+method = virtio-serial
+path = /dev/virtio-ports/org.qemu.guest_agent.0
+statedir = /var/run
+@end example
+
+The list of keys follows the command line options:
+@table @option
+@item daemon= boolean
+@item method= string
+@item path= string
+@item logfile= string
+@item pidfile= string
+@item fsfreeze-hook= string
