 Both flexibility of the virtualization technology and I/O performance of a VM are incompatible with each other. The reduction technique for overhead of virtualization technology is necessary. The goal of this study is to improve performance of network I/O of an inter-VM communication. We proposed a para-virtualized driver that is applied overhead mitigation techniques such as zero-copy and interrupt-coalecsing, and designed and implemented that driver using Infiniband.
In this study, we measured latency, packet processing rate and CPU load of hypervisor of our driver and compared the results with our driver and the system consisting of vhost-net and eIPoIB that can realize similar function with our driver. As a result, we found that the para-virtualized driver implemented in this study has advantages over the system consisting of vhost-net and eIPoIB in terms of latency, packet processing rate and CPU load of hypervisor.
