Virtualization for Embedded Systems
Virtualization has recently become important technology for embedded systems. So, it is important for embedded-systems developers to understand the power and limitations of virtualization. This paper presents an introduction to virtualization technology and specifically discusses its application to embedded systems. It explains the inherent differences between the enterprise-systems style of virtualization and embedded system virtualization. It explains virtualization’s benefits in embedded systems, and with regard to security and IP protection. It discusses the limitations of plain virtualization approaches in embedded systems. These relate to the highly-integrated nature of embedded systems, specifically security and reliability requirements. It presents the microkernel approach to virtualization, and explains the microkernel’s suitability for embedded systems. It shows how microkernels like Open Kernel’s OKL4 technology overcome limitations of plain virtualization.
