Abstract
In this paper, we are trying to address the global scheduling issues in the embedded multi-core virtualization system. Virtualization system is widely being used in the embedded device nowadays, especially with the multi-core platform also shown in the embedded system world. Global scheduling in the virtualization system makes the real-time tasks in the GPOS (General Purpose Operating System) to have chance to be scheduled against the tasks in the RTOS (Real-Time Operating System). We proposed using GPOS/RTOS mix scheduling and VCPU migration to deal with global scheduling problem. Meanwhile, some issues like interrupt latency in the GPOS and the priority inversion problem in the RTOS are also discovered while doing this research. We would like to make more detail investigation about this issues to improve the quality of global scheduling so we can construct a more ideal virtualization environment.
