Message:

VMM,RuntimeR0: Flush the log buffer directly to the parent VMM if that's the only destination, and honor the unbuffered setting when that's the case. Setting VBOX_LOG_DEST='nofile vmm' & excluding 'buffered' from VBOX_LOG_FLAGS for the inner VBox instance will result in the logging to be intermixed w/o any buffering delays and no need to try correlate events between outer and inner vbox instances. [build fix] bugref:10092
