Hi Denis,

I added the libvirt-service-type in my config.scm


  (service libvirt-service-type
            (libvirt-configuration
             (unix-sock-group "libvirt")
             (tls-port "16555")))
----------------------------------------------
  (services
     (append
       (list (service mate-desktop-service-type)
             (service enlightenment-desktop-service-type)
			(service cups-service-type
				(cups-configuration
					(web-interface? #t)
					(extensions (list cups-filters hplip))))			
			(service openssh-service-type)
             (service tor-service-type)
             (set-xorg-configuration
               (xorg-configuration
                (keyboard-layout keyboard-layout)))
             (service libvirt-service-type
                      (libvirt-configuration
                       (unix-sock-group "libvirt")
                       (tls-port "16555"))))
	
       (modify-services %desktop-services
	(guix-service-type
-------------------------------------------------

and doing a:
sudo guix system reconfigure /etc/config.scm
it gave me this message:

Where are the problems?
thanks for help
