The GENIVI Hypervisor Group standardization work aims to reduce implementation friction, to prepare for an ever increasing functional consolidation and deployment flexibility in both domain and zone based architectures. But virtualization is already being introduced in some of today's architectures. Let 3 virtualization expert companies share their experience with you and point out successes as well as pitfalls in previous deployment of virtualization technology on embedded and automotive systems. Like the other return-of-experience sessions, alternating companies will provide their unique point of view in short and intense talks. If successful, we will all come out of this presentation with a new understanding of what to focus on when choosing hypervisor implementation, and architecting the resulting system.
