16:20 How can I give virtual GPU resources to my endusers seamlessly?

While OpenStack Nova supports virtual GPU and GPU passthrough for a while now, we recently improved a few things and we provided support for the recent nVidia SR-IOV architectures. During this presentation, we'll cover the recent additions that were made and we'll show how to manage your GPU resources in order to provide them to end users, including an experimental feature that will provide GPU quotas to your users.

16:40 Introduction to ovn-bgp-agent

As data centres grow to hyper-scale, the limitations of traditional Layer 2 networking architectures are becoming apparent on scalability and performance, and there is a growing interest for pure Layer 3 deployments.
To allow that feature on OpenStack, we have been working on a new OVN based agent that can expose workloads through BGP, which we will present in this talk.

Speaker: Bernard Cafarelli (Red Hat)
