+#           of the same kind are added to the virtual machine and (b)
+#           you have configured input routing (see docs/multiseat.txt)

+#           with a console are admissible.
+#           If @console is specified, it must exist, and both devices
+#           associated with that console and devices not associated with a
+#           console are admissible, but the former take precedence.
