Together with the ovm_vmmessage
utility on the
Oracle VM Manager, the Oracle VM Guest Additions form a bi-directional
messaging channel between Oracle VM Manager and the guest. More
specifically, as part of the Oracle VM Guest Additions, a command
line tool called ovmd
is installed. It allows
first-boot installation configuration, and is capable of sending
and receiving messages consisting of key-value pairs just like the
ovm_vmmessage
utility. As you can see in the
help, ovmd
has the following command line
options:
# ovmd --help usage: ovmd [options] options: -p, --set-param=PARAM Set param in format: key=value. -g, --get-param=KEY Get param value. -r, --delete-param=KEY Delete param by key name. -x, --delete-params Delete all params. -l, --list-params List all params. -e, --event=EVENT Inject event. -s, --script=SCRIPT Run script. -d, --debug=LEVEL Set debug level: 0(DEBUG_OFF), 1(DEBUG_STDERR) or 2(DEBUG_SYSLOG). Default: 2. -f, --pid-file=FILENAME Set the pathname of the process ID (PID) file. -t, --time-period=secs Set the period for daemon mode(default=10 seconds). -v, --version Show version number and exit. -h, --help Show this help information.
