DESCRIPTION:Running thousands of snapshotted VMs pushes Linux networking to
  its limits. This talk covers battle-tested strategies balancing performan
 ce\, isolation\, and efficiency across large-scale topologies. We explore 
 Geneve tunneling for scalable overlay networks\, eBPF-accelerated networki
 ng for line-rate performance\, and stateless NAT without connection tracki
 ng overhead. Prefix-based iptables/nftables rules scale to thousands of in
 stances\, while namespace pooling minimizes snapshot operation costs. We a
 lso address RTNL lock contention and its mitigation. Attendees will learn 
 to architect network stacks for snapshotted workloads where VMs are cloned
 \, restored\, and migrated while maintaining security and predictable perf
 ormance.
