An energy-efficient hypervisor scheduler for asymmetric multi-core

Virtualization has recently become popular in the embedded-systems area. In order to apply virtualization techniques on embedded-systems, we need a hypervisor that provides a software virtualization environment. A hypervisor scheduler assigns virtual cores in a virtual machine to physical cores. Since traditional load-balanced scheduling strategy is not aware of the asymmetry of cores, its deployment to an asymmetric platform may cause performance degradation or energy waste. In this paper, we propose an energy-efficient, asymmetry-aware scheduler for hypervisor on asymmetric multi-core platform. The goal is to generate an energy-efficient scheduling plan with performance guarantee.
