Two approches to real-time virtualization - Jailhouse and KVM

Tuesday, October 11, 2016 • 10:40 - 12:00


Lightweight real-time partitioning for Linux with Jailhouse

The Jailhouse hypervisor project was created to partition multicore systems with the help of virtualization technology - and Linux. It is designed for simplicity and, thus, provides isolation between partitions at minimal costs.

This talk will briefly present the concept of Jailhouse, its latest state of development and typical use cases around real-time as well as safety critical systems. It will address the question which unique role this project can play within the Linux ecosystem.

Real Time KVM

KVM is now suitable for low latency real time workloads. Getting there required several changes to the code, which are now now upstream. Real time KVM also requires very careful system configuration. This presentation will describe some of the issues faced (and fixed) during development, and pitfalls in deploying real time KVM.


The talk addresses systems architects and developers who need to meet real-time and/or safety requirements on highly integrated network, entertainment or control systems that run Linux, or Linux aside other OSes. The talk addresses as well KVM developers and people looking to deploy Real Time KVM. There are equal amounts of magic in the code, and in system configuration.
