[maybe OT] Strange behaviour when connecting to serial port of a FreeBSD inside a VM

[Joachim Durchholz]

Sorry if this off-topic, please direct me to the correct list.

I have FreeBSD running inside a VirtualBox VM, and while FreeBSD boots 
and works fine and I could successfully hook up a host's domain socket, 
I don't see output on the socket.
SOMETHING is working: Some boot messages are redirected, though to a 
place that I do not see.

I have a shell script that recreates the entire situation from scratch, 
I can describe everything in excruciating detail - where do I start?

Regards,
Jo
