An approach to implementing the NIC virtualization by the hybrids of single system image and hardware-assisted virtualization technologies

I/O virtualizations especially NIC ones is a hot spot in the research filed. In order to utilize the global NIC resources deployed in the distributed virtual machine monitor system, this paper proposes a new approach to implement the NIC virtualization for DVMM. The approach is implemented by the hybrid of hardware-assisted virtualization and the single system image technologies, and resides in the level between the virtual machine monitor and the operating system. This implementation can fully utilize advantages of both virtualization and SSI and meanwhile avoid their defects. The implementation strategies and the experiments result reflect the approach makes features of high transparency, high availability, low dependency and low implementation cost, and can effectively collect, unify and utilize the global NIC resources deployed in each node of the distributed virtual machine monitor.
