Introduction

OpenBSD 7.5 is a UNIX-like operating system. The project’s “efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography”. Compared to modern Linux distributions OpenBSD is very compact, but comes with the usual packages and ports tree you would expect from any *BSD operating system. This article shows the process of installing OpenBSD 7.5 with virt-install, making it a virtualization guest on Linux.

Downloading the ISO installer

First you need to download the OpenBSD 7.5 ISO installer on your Linux system. On most systems the amd64 install75.iso is the correct choice. Check the OpenBSD download page for other architectures.
