KubeVirt VMs for migratable inceptionist clusters
summary
Proposal and reference CNI implementation that runs KubeVirt VMs as Cluster API nodes and uses OVN/ovn‑kubernetes CNI with DHCP options and ARP proxy to keep node IP, gateway and TCP sessions stable across live migration. Implementation uses per‑node logical switches, OVN static routes and policies to redirect ingress/egress via a point‑to‑point routine; demo proof‑of‑concept preserves TCP connections with short latency spikes (not perfect yet) and aims for ~100 ms migration downtime.
