OPNFV Summit 2015

We are working on KVM enhancements for NFV as a collaborative development project in OPNFV, focusing on three key features: minimal Interrupt latency variation, inter-VM (Virtual Machine) communication, and fast live migration. In this presentation, we introduce and provide an update on the project, and how we plan to work with the upstream KVM project.

Minimal Interrupt latency variation is required for data plane VNFs to achieve deterministic execution. We present an update, demonstrating how hardware and software enhancements can help when reducing latency variations.

We evaluate and compare the options for inter-VM communication (e.g. ivshmem, vhost user, VMFUNC, etc.) in terms of performance, interface/API, usability/programing model, security, and maintenance. 

Finally we provide and update on fast live migration, including improvements with time to co
