 In the event that you want to deploy the new node on a specifc host you can use the ``--hint same_host`` argument e.g. ``openstack server create --hint same_host=2e838a71-f6d9-46c4-94f9-dd0c6a2632fe``.

If you do not wait then the unit files for the node on the autopkgtest-lxd-worker will fail as there will be missing images for releases. You can also use ``lxc image list`` to check what was correctly built, and finish the work manually if needed. Commands should be in the cloud-init log.
 
 And you then need to add the IP to the ``autopkgtest-lxd-worker``
 ``lxd-remotes`` section, in the ``service-bundle`` for example:
