Hypervisors and realtime Linux Training
Hands-on course
- Program
- Participants / Prerequisite
- Intra/Tailored
Program
At the end of this training you will be able to choose between the different realtime solutions for Linux and to develop realtime applications based on Linux-RT, Xenomai or a realtime hypervisor architecture.
Case study
The exercises are proposed using skeletons to be completed to allow the student to write a realtime application and to interface it with Linux.
PROGRAM
Virtualisation using Linux
- Overview of virtualization. History. Theory of virtualization. Virtualization types and modes.
- The new virtualization helpers in modern CPU, Intel VTX and ARM Trust-zone.
- Virtualization gains. Securing a system by diminution of the trusted software base.
- Virtualization using Linux. Namespaces and application virtualization.
- Overview of QEMU and KVM. Focus on XEN.
The XEN Hypervisor
- Presentation of the XEN Hypervisor. Installation, commands overview.
- Storage management, console, networking with XEN.
- CPU virtualization, scheduling, checkpoints and migration.
- Limits of the XEN scheduling. Tries to makes XEN realtime.
- The XEN Development interface.
Hands-on work
