In connected devices with mixed-criticality deployment, virtual machine technology (i.e., hypervisor) enables secure isolation and management. Most of the existing mainstream commercial hypervisor solutions are closed-source, while the open-source Linux KVM solution is a non-real-time virtual machine. Based on ARM64 and Zephyr RTOS, we developed an embedded real-time virtual machine named ZVM (Zephyr-based Virtual Machine). We can start and run Linux OS and Zephyr RTOS in ZVM. The main functional modules for implementing ZVM include CPU virtualization, memory virtualization, interrupt virtualization, I/O virtualization, and timer virtualization. We completed the implementation, integration and optimization of each virtualization module. ZVM is an open source embedded real-time virtual machine with a good license.
