The new runqemu prints a lot of info/debug messages to the console. We should rein this in so that only useful messages are logged by default and some of the scary looking messages ("Can't find qemuboot conf file, DEPLOY_DIR_IMAGE is NULL!") are hidden in normal use. Most of the messages which are currently logged as INFO should be suppressed, i.e. overriding conf file settings, unable to find qemuboot.conf, etc.
