mklinux-v7.0-mk2 released

For people who would like to experiment with the multi-kernel Linux concept, Cong Wang has announced the release of mklinux v7.0-mk2.

mklinux lets one machine run several independent Linux kernels at the same time on bare metal, without a hypervisor. A host kernel owns a pool of CPUs, memory and PCI devices, carves that pool into instances, and boots a spawn kernel into each instance through kexec_file_load(). Every spawn kernel runs natively on its own CPUs, its own physical memory and its own devices. Nothing is emulated and nothing is trapped; the only thing shared is what you choose to share.

Note that this is not the old MkLinux, which was a port to PowerPC Macintosh systems.

I really got a surprise seeing mklinux, I was for a brief time a user of MkLinux on an old PowerPC Mac! But as the article clearly says, this is something new and different. Nostalgia was triggered though.

Not just PPC!

(I don't think we used anything from it; the Linux/PA-RISC port started from scratch)
