My libvirt-based Vagrant box failed to start with a cryptic error message. I fixed it by renaming the box from “default” to “trixie”, which is a pretty cryptic way of fixing a VM.

While debugging this I learned about Vagrant 3.0 - a Golang rewrite, that was announced in 2021 by Chris Roberts and Sophia Castellarin.

The last mention of this project is from 2025 in PR #13622, that provides this much information:

Removes the vagrant-go implementation. A backup of the work has been retained on the vagrant-go branch.

Fun fact: the PR author is the very same Chris Roberts who announced it 4 years earlier.
