I've also added that simple-service to my os config, this is a snippet:

--8<---------------cut here---------------start------------->8---

[...]

	(services
	 (append %desktop-services
		 (list
		  ;; libvirt and virtlog daemons
		  (service libvirt-service-type
			   (libvirt-configuration
			    (unix-sock-group "libvirt")
			    (tls-port "16555")))

		  (service virtlog-service-type
			   (virtlog-configuration
			    (max-clients 1000)
			    (max-size 5)
			    (max-backups 9)))

		  (service xfce-desktop-service-type)
		  
		  (set-xorg-configuration
		   (xorg-configuration
		    (keyboard-layout keyboard-layout)))
		  
		  ;; extend polkit for spice-gtk
		  (simple-service 'spice-polkit polkit-service-type (list spice-gtk))

but when I try to apply it I get this error:

AFAIU polkit-service-type is defined in (gnu services desktop) and I'm
including that module: what am I doing wrong please?

Thanks! Gio'
