Abstract

This paper aims at qualitatively evaluating the performance of routing virtual environments built with KVM and Xen virtualization platforms, combined with the OpenFlow protocol, which is used for creating Software-Defined Networking (SDN). Initially, Xen and KVM were installed on modern x86 servers to compare their CPU, RAM memory access and networking performances. Results show that KVM, when Virtio is used, despite being a full virtualization platform, has better memory, CPU and networking performance than Xen. Furthermore, the Xen VM packet routing performance is better than Xen routed, and almost equal to the KVM and native Linux, when they are installed with OpenFlow to separate the router control plan from router data plan.
