After a short introduction to the goals and approach of the Superfluidity EU research project, we present the proposed extensions to OpenVIM to support ClickOS Unikernels and Xen.
We have implemented a scenario that can combines Unikernels and regular VMs in the same Network Service or VNF extending OpenVIM.We describe how we have extended the ETSI NFV models and OpenVIM. In particular, we provide the details of the OpenVIM descriptor extensions to support Unikernels.
As a background information, we discuss the Unikernels and their orchestration aspects. Unikernel technology allows to build tiny VMs with memory footprint in the order of hundreds of KBs and boot time in the order of milliseconds. We focus on ClickOS Unikernels. We have adapted 3 VIMs (OpenStack, Nomad, OpenVIM) to support ClickOS Unikernels and report a performance evaluation of the VM instantiation time.
