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 scheduling 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: mmu isolated approach; 3:single-process purpose OS; 4: AMP approach; and then we provided a hybrid solution to meet real-time virtualization and edge computing with some potential use cases.
