Resolution

Restart the salt-minion service and apply the highstate:

systemctl restart salt-minion
salt-call saltutil.sync_all
salt-call state.apply

If the client is using the salt bundle, restart the venv-salt-minion service:

systemctl restart venv-salt-minion
venv-salt-call saltutil.sync_all
venv-salt-call state.apply

NOTE: Note that the saltutil.sync_all and state.apply commands can also be run against multiple minions from the SUSE Manager (salt master) server instead of locally calling from a client as per the above examples.

Cause

Deploying of the beacon is not automatic currently.
