A technical experiment running 5000+ virtual Linux IoT devices using the Nerves framework on an Ampere One 192-core ARM64 server. The breakthrough came from implementing KVM acceleration and a custom bootloader called little_loader, which dramatically improved performance and reduced memory usage. Each virtual machine runs a complete embedded Linux system with the BEAM VM, consuming around 160MB RAM and booting in single-digit seconds. The setup demonstrates practical applications for testing embedded systems at scale and validates the viability of running thousands of concurrent Nerves devices for development and testing purposes.
