Unsure if this is a lost cause, but I continue to hope for VBox guest additions support for OpenBSD one day. Recent VBox + OpenBSD releases and CPU virtualization features have smoothed out issues encountered in the past. Usability enhancements on the guest additions end seems to be the one main gap at this point.
I just wanted to tap the community here to ask any other interested users to (kindly, professionally) lend support to the enhancement ticket to voice interest in acheiving this. https://www.virtualbox.org/ticket/17817 -- Darren Spruell phatbuck...@gmail.com
