Would you mind posting a link to 'Jailhouse' for the lazy ones?
There you go:
https://github.com/siemens/jailhouse
README:
Jailhouse is a partitioning Hypervisor based on Linux. It is able to run bare-metal
applications or (adapted) operating systems besides Linux. For this purpose it configures
CPU and device virtualization features of the hardware platform in a way that none of
these domains, called "cells" here, can interfere with each other in an
unacceptable way.
Jailhouse is optimized for simplicity rather than feature richness. Unlike full-featured
Linux-based hypervisors like KVM or Xen, Jailhouse does not support overcommitment of
resources like CPUs, RAM or devices. It performs no scheduling and only virtualizes those
resources in software, that are essential for a platform and cannot be partitioned in
hardware.
Once Jailhouse is activated, it runs bare-metal, i.e. it takes full control over the
hardware and needs no external support. However, in contrast to other bare-metal
hypervisors, it is loaded and configured by a normal Linux system. Its management
interface is based on Linux infrastructure. So you boot Linux first, then you enable
Jailhouse and finally you split off parts of the system's resources and assign them to
additional cells.
