We already have a check but that does not trigger when there is an iPXE template associated, that is the case:

    if host.provisioning_template({:kind => host.operatingsystem.template_kind}).nil? && host.provisioning_template({:kind => "iPXE"}).nil?
      failure _("No %{template_kind} templates were found for this host, make sure you define at least one in your %{os} settings") %
                { :template_kind => host.operatingsystem.template_kind, :os => host.operatingsystem }
    end
