The “Jailhouse” Hypervisor

The Jailhouse project has announced its existence. Jailhouse is a Linux-native hypervisor like KVM, but with a focus on minimalism and isolation of virtual machines on dedicated CPUs. “Jailhouse is a partitioning hypervisor that can create asymmetric multiprocessing (AMP) setups on Linux-based systems. That means it runs bare-metal applications or non-Linux OSes aside a standard Linux kernel on one multicore hardware platform. Jailhouse ensures isolation between these ‘cells’, as we call them, via hardware-assisted virtualization. The typical workloads we expect to see in non-Linux cells are applications with highly demanding real-time, safety or security requirements.” The project is in an early stage and looking for interested developers.
