Experimenting with Firecracker microVMs at work for developer environments. So far I have: - Developers login with GitHub and get a box - Box is reachable via SSH and will auto-start - Box can be stopped/recreated from UI Each box - 32G ram - Mise with tools/agents pre-installed - Paseo relay

Host machine and architecture - Nobody needs to access it - VM API is a non-root user w. KVM access - Management CLI for setting up systemd/firewall - Services run via SystemD - Web interface is separate from VM management Stack is Go and a little SQLite

Developers can then use: - SSH client and run Claude/Codex/etc from there - Zed via SSH - Visual Studio Code Remote - Jetbrains IDE w. remote SSH or whatever they want, as long as it can connect via SSH

Non-goals: - Multiple host-machines or a cluster scheduler. I'm not building Kubernetes! - Anything that unnecessarily increases the exposure of the VM manager API
