ELC17: Xen and the art of embedded virtualization
Hypervisors are becoming more and more widespread in embedded environments, from automotive to medical and avionics. Their use case is different from traditional server and desktop virtualization, and so are their requirements. This talk will explain why hypervisors are used in embedded, and the unique challenges posed by these environments to virtualization technologies. Xen, a popular open source hypervisor, was born to virtualize x86 Linux systems for the data center. It is now the leading open source hypervisor for ARM embedded platforms. The presentation will show how the ARM port of Xen differs from its x86 counterpart. It will go through the fundamental design decisions that made Xen a good choice for ARM embedded virtualization. The talk will explain the implementation of key features such as device assignment and interrupt virtualization.
