Multikernel Linux Tree Released: Runs Multiple Kernels On Bare Metal Without a Hypervisor
↗
A new Linux tree allows multiple independent kernels to run natively on the same physical server, each with dedicated hardware resources and no hypervisor layer.
This approach could reduce overhead for workloads requiring strict isolation while avoiding the complexity of traditional virtualization. Engineers may need to evaluate whether the hardware partitioning model fits their use cases better than VMs or containers. The project is still x86_64-only, limiting immediate adoption.

Each kernel instance runs on dedicated CPUs and memory, avoiding resource contention between workloads.
The host kernel manages hardware allocation via device tree overlays, enabling dynamic reallocation without downtime.
Current support is limited to x86_64, with other architectures planned for future releases.
