Yes. You first create a cloud that runs baremetal instances (perhaps in recent versions of RHOSP they can also be VMs, not sure). It's called the undercloud.

OpenStack is automatically deployed on those instances. That is then the overcloud.

certain instances communicate by network1 other by network2-supposing we have network1 and networks defined. can be baremetal instances or overcloud instances.yes?tnx openvswitch is used in openstack because is very flexible-mean the vlan can be created very easy.yes?

To connect baremetal instances to Neutron networks, special steps are required.
