OpenBSD/arm64 on Hetzner Cloud
Hetzner introduced its Ampere Altra powered arm64-based cloud servers earlier this year, making it possible to easily run OpenBSD/arm64 on their platform.
The only caveat for now is that the viogpu(4) driver is required, which was committed by jcs@ in April 2023 and thus only available in snapshots. It will first appear in OpenBSD 7.4.
Excellent news.
