summary
Hands-on workshop showing OVN‑Kubernetes + CNI + KubeVirt on KIND clusters to achieve regulatory UDN per-namespace isolation where pods and VMs get separate IP spaces (examples: 103.x, 203.x, 192.x) and default kubelet probe IP stays at 10.244; cluster services use a clusterwide service CIDR; cross‑UDN pod IP connectivity is blocked unless an interconnect CRD is added; VM live migration preserves IP and MAC via an IPAM claim CRD, surviving migration with only a brief packet hiccup. Kubernetes support begins at 1.32.
