To enable (almost) all logging, do:
export VBOX_LOG=+all.e.l.f
export VBOX_LOG_FLAGS=time\ tid\ thread
export VBOX_LOG_DEST=dir=<dir_where_to_put_log_files_to>
Please note that this will generate really huge log files and slow down
VM execution. If you need to track down a problem in a particular
component, you can only enable logging for this component (or a set of
components). Refer to VBOX_LOGGROUP_NAMES defined in include/VBox/log.h
for a list of components and use names there instead of 'all' above.
