to the channel (usually a chardev with a unix socket front-end and
So we can activate it, but we won't receive response.
But,we can use timeout and assume that guest agent is not running ?
exemple : if we want to use guest agent to shutdown
try with guest agent, "guest-shutdown", if no reponse, try with monitor command ?
