Virtualization technologies has already been deployed in the embedded systems but in many use scenarios, applications/services should be responded in real time. Some typical hypervisors are constructed to be a real time hypervisor but this solution still cannot meet hard time requirement, even real time guest OS is adopted. Because hypervisors have no knowledge of tasks inside VM actually. So based on this two levels of shcedule domain, I’d like to discuss-to review #1. What are those challenges, #2. Benefits with Real Time virtualization; #3. Several potential but different approaches to construct real time virtualization solution:1:paravirtualize guest OS like Linux to sync scheduling between GOS and hypervisor ;2:AMP hypervisor;3:single-process purpose OS; 4 EPT-only protected application/service; 5.some possible combinations, #4. Any potential but valuable use cases.
