OpenBSD 7.3 on VirtualBox 7: Installation as guest OS failed due to I/O APIC enabled

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"...πŸ€•

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.)

Installing bsd 0% (...)
dc_atapi_start: not ready, st = 40

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 πŸ™‚
