(English Abstract)
In a virtualization platform, I/O interrupt is propagated to a corresponding virtual machine through a hypervisor. A virtual machine scheduler in the hypervisor preferentially schedules the virtual machine. This mechanism enhances the quality of service in the I/O virtualization in common cases. However, the mechanism has hazards such that a skewed workload can cause monopolization or a race condition in CPU resources. Therefore, a hypervisor requires a virtual machine scheduler that considers the trade-off between fairness and response time in virtual machine scheduling. In this paper, we propose a fair and responsive virtual machine scheduler. The proposed scheme dynamically adapts the priorities of virtual machines based on provisions on the execution patterns of the virtual machines. We evaluated the proposed scheme with simulations. The result showed that the proposed scheme provides a fair and responsive scheduling algorithm with low computational overheads.
