As HPC and AI/ML workloads move to cloud-native environments, demand for low-latency networking in virtualized setups is critical. KubeVirt runs VMs alongside containers, but achieving bare-metal InfiniBand performance—the backbone of true HPC—has remained challenging.
This session explores InfiniBand integration into KubeVirt using the SR-IOV Network Operator. We'll cover architecture and how the operator automates managing InfiniBand VFs across Kubernetes clusters. IB introduces unique complexities: GUID management, IPoIB vs. RDMA modes, and passing these capabilities into VMs.
Join the SR-IOV Operator and KubeVirt networking maintainers for a technical deep-dive. Our demo will showcase VM-Pod communication over IB VFs on a single node, and scale-out performance between VMs across nodes.
You'll learn about KubeVirt's design philosophy,architectural decisions treating InfiniBand as first-class in the SR-IOV Operator, and how to deploy InfiniBand networking for VMs in your clusters.
