Alright, so at least that is expected behavior, then. Thanks.


Well the only other thing I can think of to assist in troubleshooting the
issue, is to enable some logging ? I took a look at these wiki pages :

https://www.virtualbox.org/wiki/VBoxMainLogging
https://www.virtualbox.org/wiki/VBoxLogging

But I couldnt see any values for VBOXSVC_RELEASE_LOG and
VBOXSVC_RELEASE_LOG_FLAGS that might be helpful in this particular case.
(or flags and options to supply to 'VBoxManage debugvm <name> log foo',
which seems slightly neater than using the environment variables.)

I browsed through the stuff located in 'include/VBox/log.h' as pointed out
in that page, but couldnt find anything immediately obvious.
https://www.virtualbox.org/browser/vbox/trunk/include/VBox/log.h

(Also a debug build may be useful for debug log purposes, but I cannot find
pre-build debug builds for Windows on the web site).
