+          qemu: Set DAC permissions properly for spice rendernode
+        </summary>
+        <description>
+          When a <code>rendernode</code> path is set for SPICE GL on
+          <code>qemu:///system</code>, we now correctly set DAC permissions
+          on the device at VM startup. This is the last remaining hurdle to
+          let SPICE GL work for <code>qemu:///system</code> without any
+          external host changes.
