In industrial and real-time embedded environments, system uptime and fault recovery are mission critical. This proposal explores a lightweight and effective technique for crash detection and recovery using Inter-VM Shared Memory (IVSHMEM) within the Jailhouse hypervisor. By continuously sharing heartbeat or health status between the root cell and inmate (guest OS) via shared memory, the system can quickly detect unresponsive partitions and trigger recovery mechanisms like automated restarts without a full system reboot. We demonstrate this approach on TI SITARA EVMs, showing how it minimizes downtime without a full system reboot. Through this talk, I aim to share a reusable pattern for enhancing system reliability and show how open-source virtualization can be leveraged for resilient industrial applications. Attendees will gain insights into partitioned system design, shared memory communication, and recovery strategies for embedded systems. I hope to receive feedback on enhancing this approach and hear from others solving similar reliability challenges in embedded systems.
