You should be able to power-down the NUC boxes and move them to another place. The should power-up and be reconnected using the same addresses they were assigned in the install (at least this works for the 3-node deploy). The procedure to power-up is:

• power-on all the nodes, in this order
  • jumphost
  • controller
  • compute
    • you might want to wait a few minutes so that the controller boots fully and OpenStack services are initialized. Otherwise you may get a "no valid host found" error when starting VMs, and need to restart nova service on the compute host to resync with the controller. Starting from the jumphost:
      • ssh root@192.168.1.205
      • restart nova-compute *
• SSH into the jumphost (root/Op3nStack) and restart the Foreman VM

sudo ssh root@restart nova-compute
cd /var/opt/opnfv/foreman_vm
vagrant up

• wait a short while, and on your test driver node browse to:
  • the Foreman UI at https://192.168.1.202 (login: admin/octopus)
  • the Horizon UI at http://192.168.1.204 (login: admin/octopus)
  • the DLUX UI at http://192.168.1.204:8181/dlux/index.html (login: admin/admin)
• It should take a little while, but the Foreman status for the nodes ("Hosts") should return to "A" (active)
