Thanks for suggestion.
Perhaps you are right, furthermore I can not see FreeBSD version of
that function, so currently we have at least two different approaches:
- Rollback to an old version of system memory calculation method
(which was a dirty hack,according to code comments)
- Or just implement such function and send it upstream.
The second way seems to me more preferable. It takes me a few days,
until that you have to use cli tools or previous VirtualBox port
revision from svn.
