Hello,

I am trying to get USB redirection working with libvirt, but I am 
hitting a snag. Originally it was not able to redirect the USB devices 
due to spice-client-glib-usb-acl-helper not being available in 
/run/setuid-programs. I was able to resolve that by appending the 
spice-gtk version of spice-client-glib-usb-acl-helper into my 
setuid-programs list. However, I am now getting a new error:

Error setting USB device node ACL: 'Error PoliciKit error: 
GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Action 
org.spice-space.lowlevelusbaccess is not registered' (0)

It fails no matter which client I use (virt-manager, virt-viewer, 
gnome-boxes). Is there a way to fix that permission so I can redirect my 
USB devices?


Thanks!

I had the same problem some time ago. It can be fixed by extending
polkit-service-type with spice-gtk, i.e.

(operating-system
  ...
  (services
    ...
    (simple-service 'spice-polkit polkit-service-type (list spice-gtk))))

Hello,

sorry to resurrect an old message but I've the same issue reported on
Nov 2023 by TakeV and the provided solution does not work for me

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))

[...]

--8<---------------cut here---------------end--------------->8---

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

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

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

Thanks! Gio'

No I was wrong, polkit-service-type is in dbus service module: I added
it and I was able to define that simple-service

Sorry for the noise!

Happy hacking! Gio'
