USB redirection via libvirt

USB redirection via libvirt

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))))

That worked! Thank you so much.
