Multi-node
A multi-node cluster can be created by creating multiple VMs connected via the (lima:user-v2 network.
limactl create --name k8s-0 --network lima:user-v2
limactl create --name k8s-1 --network lima:user-v2
The cluster has to be set up manually, as the built-in templates do not support multi-node mode yet. Support for multi-node template is tracked in https://github.com/lima-vm/lima/issues/4100.
