Logging is normally automatically enabled in debug builds. So if you compile VirtualBox with export BUILD_TYPE=debug kmk then the resulting build will be able to create debug log files. However, that build will also include a lot of assertions and additional code for debugging which makes VirtualBox slow. If you only want to enable logging then you have to add the following line to LocalConfig.kmk in the root directory of the VirtualBox tree: DEFS += LOG_ENABLED After doing so, you have to recompile the whole beast of course. When running VirtualBox, make sure to do export VBOX_LOG=+all.e.l.f -- the 'export' is important if you want to log the VBoxSVC server as well. The log files are created in the current directory.
