No - you can change the cluster settings (virt service/gluster service) 
only if the application mode is "both". In virt only mode, the cluster 
is virt only, and same with gluster-only. So if you want user to be able 
to change the mode *after* installation, this config (ApplicationMode) 
must be exposed in the engine-config tool.
