The 3x 6GB nodes are OOM (k3s-dev-2's kubelet stopped; dev-1/dev-3 <600MB free). KubeVirt runs
a full control plane (~1.5-2GB) for ZERO running VMs — its IaaS conformance (R-PLAT-03/04,
R-NET-01, R-STATE-01) is already certified, so disabling the running pods loses no delivered
capability. Re-enable (uncomment kubevirt in platform + platform-config) once the VMs' RAM is
grown. Manifests retained; reversible.
