Multikernel Technologies releases mklinux v7. 0-mk2

mklinux multikernel Linux kernel bare metal kexec

Multikernel Technologies has released mklinux v7. 0-mk2, the first public version of its multikernel Linux tree. This architecture allows multiple independent Linux kernels to run simultaneously on a single physical machine without the need for a hypervisor or containers.

In this setup, a host kernel manages the system's hardware, including CPUs, memory, and PCI devices. It uses the kexec mechanism to boot additional kernel instances directly onto dedicated slices of hardware. This allows for strict resource isolation; for example, a database and a GPU training process could run on the same server without interfering with each other's resources.

Key technical features include the ability to shift hardware resources between running kernel instances via device tree overlays without requiring a system reboot. Performance benchmarks conducted on a Dual-Socket-Xeon Gold 5418Y indicated that context switching is 2.5 times faster than a KVM guest. While the current release is limited to x86_64 hardware, the company stated the architecture is modular enough to support future ports.
