The Citrix Hosting Server service was discovered on every machine that reported a Citrix controller, even if the machine reported no hosting server, for example a machine with the power state Unmanaged. On such machines the service crashed with KeyError: 'hosting_server'.

The service is now only discovered on machines that report a hosting server. Already discovered services on machines without a hosting server no longer crash; they are reported as vanished and can be removed by running a service discovery.
