Zero-Overhead Virtualization - Challenges and Pitfalls Across Architectures

Explore the challenges and possibilities of zero-overhead virtualization in embedded systems through this insightful 40-minute conference talk. Delve into the world of mixed-criticality scenarios and system consolidation using powerful CPU cores in embedded processors. Examine the use of virtualization extensions to achieve strong isolation between computing domains while maintaining real-time properties. Learn about the Linux-based hypervisor Jailhouse and its approach to static partitioning for zero-overhead virtualization. Investigate the architectural limitations of ARM, x86, and RISC-V platforms in achieving this goal. Discover common pitfalls, barriers, and ongoing developments in embedded zero-overhead virtualization across different architectures. Gain valuable insights into the future of virtualization in embedded systems and the challenges that need to be addressed.
