Demo of live container migration using Virtualbox, Vagrant and ShutIt

In plain words

This automated demo illustrates live container migration using CRIU (Checkpoint/Restore In Userspace) technology combined with Virtualbox, Vagrant, and ShutIt. It shows how containers can be checkpointed and restored across systems, demonstrating a technique that simplifies moving running applications by keeping their dependencies self-contained. The demo is interactive and annotated, designed for developers interested in understanding Docker's migration capabilities and exploring checkpoint-restore functionality in containerized environments.

An automated, annotated, interactive demo of live container migration using Virtualbox, Vagrant and ShutIt. CRIU is a technology designed to allow the checkpointing and restoration of programs in userspace in the Linux kernel. Containerization is a natural fit for this, since in theory most of its dependencies are contained and thus easier to reason about. Work is proceeding on this technology, and this demo gives a flavour of what’s possible. It’s based on a post Circle-CI recently published. I think this technology is a giant leap forward for Docker. The applications for this for testing, delivery and operations are immense.…from zwischenzugs.wordpress.com

  Lightweight tool for managing Linux virtual machines2025 · github.com · ▲144

  hey guys. the other day i was migrating hosting providers and i just needed something not too heavy and convenient to spin up my backups for awhile and realised there is almost nothing out there. kimchi hasn't been updated for years and cockpit is heavy. so here's something i came up with in a couple hours because of a sudden urge, nothing fancy just basic creation with cloud init, lifecycle management and image/storage, but it's modern-ish and it compiles to a 8.4mb binary inclusive of the embedded web UI, CLI and API, and only dep is libvirt.

  I've built a nice home server OSApr 2026 · lightwhale.asklandd.dk · ▲194

  ohai! I've released Lightwhale 3, which is possibly the easiest way to self-host Docker containers. It's a free, immutable Linux system purpose-built to live-boot straight into a working Docker Engine, thereby shortcutting the need for installation, configuration, and maintenance. Its simple design makes it easy to learn, and its low memory footprint should make it especially attractive during these times of RAMageddon. If this has piqued your interest, do check it out, along with its easy-to-follow Getting Started guide. In any event, have a nice day! =)

  GhostBox – Borrow a disposable little machine from the Global Free TierMay 2026 · ghost.charity · ▲126

  I built this because I was always creating machines on GH actions to test builds on different OS, and I wanted a tight CLI that could do it. I always saw Actions as this great resources and ephemeral machines you could do dev work in just were a natural way for me to work, so this grew out of that workflow. I didn't expect it to blow up, so it wasn't 100% finished when I posted it. But it should stabilize pretty quickly. Happy to know what you think and talk about it.

  We kept hitting the same wall: you clone some arbitrary repo and just want it to run without any configuration work. So we built Keystone, an open source tool that spins up a Modal sandbox, runs Claude Code inside it, and produces a working .devcontainer/ config (Dockerfile, devcontainer.json, test runner) for any git repo. We build on the dev container standard, so the output works with VS Code and GitHub Codespaces out of the box. Main use cases: reproducible dev/CI environments, self-describing repos, and safely sandboxed coding agents. Our goal is to encourage all repos to…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
