Do you want maximum release logging (available in all builds, and 
matches the file name you're mentioning) or do you want maximum debug 
logging (using a different file name)?

There's API support for controlling the VBoxSVC release logging (which 
is persistent, i.e. affects future VBoxSVC starts). Thanks for asking, 
because it reminded me that there's no way to query/set it using 
VBoxManage. Will add that straight away, and it should make it into BETA4.

It will work the following way:
VBoxManage setproperty loglevel "log spec"

Default (selected when using "") is "all", and maximum logging is 
selected with "all=~0".

See https://www.virtualbox.org/wiki/VBoxLogging for more information 
about logging.
