Learn how network traffic flows within OpenStack installations using the ML2/OVN driver through practical demonstrations and troubleshooting techniques in this 30-minute conference talk by Vadim Ponomarev from the OpenInfra Foundation. Explore three critical traffic flow patterns: East-West communication between instances, Source Network Address Translation (SNAT) for outbound connectivity, and Floating IP configurations for inbound access. Discover practical hacks and debugging strategies to diagnose and resolve common networking issues that arise in OVN-based OpenStack deployments. Master the fundamentals of OVN network analysis without getting bogged down in driver comparisons or theoretical debates, focusing instead on hands-on problem-solving approaches that build confidence in troubleshooting real-world network problems.
