Create floating IP:

openstack floating ip create <public_network_name>

Assign floating IP to created VM:

openstack server add floating ip <vm_instance_ID> <floating_IP>

Deletion of VM and resources:

openstack server delete <instance_ID>
openstack router remove subnet <router ID> <subnet ID>
openstack router delete <router ID>
openstack subnet delete <subnet ID>
openstack network delete <network ID>
