Virtualizing Embedded Systems - Why Bother?

Executive Summary

Platform virtualization, which supports the co-existence of multiple operating-system environments on a single physical platform, is now commonplace in server computing, as it can provide similar isolation as separate physical servers, but with improved resource utilisation. In the embedded space, virtualization is a new development, which is likely to become more widespread in the next few years. Unlike the server world, where virtualized systems typically run multiple copies of the same (or similar) operating systems, most uses of virtualization in the embedded space are heterogenous, combining different classes of operating systems: an RTOS for traditional embedded real-time programming, and a fully-featured ("Rich") operating system to support complex applications such as user interfaces.
