Change OpenBSD screen resolution in VirtualBox
Unfortunately #VirtualBox Guest Additions doesn't support #OpenBSD. However, this doesn't mean that we cannot change the screen resolution. It just needs to be set manually.
Run these two commands to fix:
On host machine: curl -sL https://git.io/J03Fb | sh -s 'Virtual machine name' '1920x1080x32'
On guest machine (OpenBSD): curl -sL https://git.io/J03jS | sh -s 1920x1080
Change [Virtual machine name] and screen resolution to your needs.
