NAME

qemu-ga - QEMU Guest Agent

SYNOPSIS

qemu-ga [OPTIONS]

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: o get information from the guest o set the guest's system time o read/write a file o sync and freeze the filesystems o suspend the guest o reconfigure guest local processors o set user's password o ... qemu-ga will read a system configuration file on startup (located at q/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).

OPTIONS

-m, --method=method Transport method: one of B<unix-listen>, B<virtio-serial>, or B<isa-serial> (B<virtio-serial> is the default). -p, --path=path Device/socket path (the default for virtio-serial is B</dev/virtio-ports/org.qemu.guest_agent.0>, the default for isa-serial is B</dev/ttyS0>) -l, --logfile=path Set log file path (default is stderr). -f, --pidfile=path Specify pid file (default is B</var/run/qemu-ga.pid>). -F, --fsfreeze-hook=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 B</etc/qemu/fsfreeze-hook>). If using -F with an argument, do not follow -F with a space (for example: B<-F/var/run/fsfreezehook.sh>). -t, --statedir=path Specify the directory to store state information (absolute paths only, default is B</var/run>). -v, --verbose Log extra debugging information. -V, --version Print version information and exit. -d, --daemon Daemonize after startup (detach from terminal). -b, --blacklist=list Comma-separated list of RPCs to disable (no spaces, B<?> to list available RPCs). -D, --dump-conf Dump the configuration in a format compatible with F<qemu-ga.conf> and exit. -h, --help Display this help and exit.

FILES

The syntax of the 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. # 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 The list of keys follows the command line options: daemon= boolean method= string path= string logfile= string pidfile= string fsfreeze-hook= string statedir= string verbose= boolean blacklist= string list
