Design and Implementation of Automotive Virtualization Based on Xen - Sung-Min Lee, Samsung Electronics

This talk presents a production-ready automotive virtualization solution with Xen. The key requirements that we focus are super-fast startup and recovery from failure, static virtual machine creation with dedicated resources, and performance effective graphics rendering. To reduce the boot time, we optimize the Xen startup procedure by effectively initializing Xen heap and VM memory, and booting multiple VMs concurrently. We provide fast recovery mechanism by re-implementing the VM reset feature. We also develop a highly optimized graphics APIs-forwarding mechanism supporting OpenGLES APIs up to v3.2. The pass rate of Khronos CTS in a guest OS is comparable to the Domain0’s. Our experiment shows that our virtualization solution provides reasonable performance for ARM-based automotive systems (hypervisor booting: less than 70ms, graphics performance: about 96% of Domain0).
