This paper introduces ViMo-S, a type 1 hypervisor for ARMv7 and ARMv8-based ARM server systems. It supports full virtualization to run existing operating systems and applications unmodified. It uses ARM hardware virtualization extensions to optimize the performance of virtual machines, especially system call latency. Therefore, its virtual machines' system call latency is near physical machine's, while other hypervisors like Xen and KVM show relatively slower and unstable performances in benchmark tests.
