Problem
With VirtualBox 7.0, installing OpenBSD 🐡 7.3 as guest on Artix Linux 🐧 as host failed.
It was because of vbox Settings, in which checked (by default) was System - Motherboard - “Enable I/O APIC”…🤕
Although I don’t know it has something to do with the failure, I found VirtualBox documentation telling:
software support for I/O APICs has been unreliable with some OSes other than Windows.
Error
It happened just after I finished answering to the OpenBSD installer and installation began. (See the first line below.)

Solution
I had to uncheck “Enable I/O APIC” of System - Motherboard in VirtualBox Settings to successfully install OpenBSD as guest.
Anyway, it solved my problem 🙂
