* '''eth1''' - A host private network called '''docker-machines''' is automatically created to ensure we always have connectivity to the VMs.
** The docker-machine ip command will always return this IP address which is only accessible from your local system.
** That network is to be used for the swarm management, node to node communication (as this data is very sensiblesensitive), so this ip has to be provided in the '''--advertise-addr''' parameter in the "'''docker swarm init'''" or in the "'''docker swarm join'''" command.
* '''eth0''' - You can specify any libvirt named network. If you don't specify one, the "default" named network will be used.
** Typically this would be your "public" network accessible from external systems
