Embedded systems virtualization : Xen on ARM processor
Κοκκίνης, Αθανάσιος Κ.
The introduction of virtual machine technology in the field of embedded system is an significant evolution. The isolation of the critical applications from the rest computing system in addition with the ability of using different operating systems is a novel step in the area of embedded systems. However, the above technology comes at a cost as it adversely affects the system performance. In this thesis we study a new generation of ARM processors with enhanced features for virtualization support in combination with the Xen hypervisor. More specifically, we study the virtualization of the Armv7 processors, that contain architectural enhancements for the elimination of the performance degradation caused by virtualization. The goal of this master thesis is the analysis and the identification of the components which degrade the system performance. To assess the theoretical study of the ARMv7 and Xen hypervisor, we also performed an analytical set of experiments using various software benchamrks.
