This talk presents a multikernel Linux architecture where multiple independent Linux kernel instances execute on a single machine with kernel-enforced resource partitioning. Unlike previous replica-based multikernel design, our isolation-based design addresses dynamic resource management through device tree based allocation and Linux hotplug operations. We discuss the architectural design, implementation leveraging existing kernel infrastructure: kexec, device tree, hotplug subsystems. Use cases include AI agent sandbox, zero-downtime kernel updates and automatic crash recovery with backup kernel. This design maintains full Linux compatibility while providing strong isolation without virtualization overhead.
