@example @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 @item statedir= string @item verbose= boolean @item blacklist= string list @end table @c man end @ignore @setfilename qemu-ga @settitle QEMU Guest Agent @c man begin AUTHOR Michael Roth <mdroth@linux.vnet.ibm.com> @c man end @c man begin SEEALSO qemu(1) @c man end @end ignore
