KIND_WORKERS=N creates N worker nodes besides the control plane. Default 0 keeps the single-node cluster. A privileged node has a /dev/kvm of its own and the script chmods it on every node, so the workers need no bind mount. Signed-off-by: Davanum Srinivas <davanum@gmail.com>
KIND_ is the environment namespace kind itself reads. Signed-off-by: Davanum Srinivas <davanum@gmail.com>

One kind node runs at most 110 pods, the kubelet default, and one atelet. The scale tests on one large host need more than that, so they spread the WorkerPools over several worker nodes on that host.
Set
ATE_KIND_WORKERS=Nwhen runninghack/create-kind-cluster.shto add N worker nodes alongside the control plane. The default remains a single-node cluster (ATE_KIND_WORKERS=0).
