+#
+# @CommandNotFound: the requested command has not been found
+#
+# @DeviceEncrypted: the requested operation can't be fulfilled because the
+#                   selected device is encrypted
+#
+# @DeviceNotActive: a device has failed to be become active
+#
+# @DeviceNotFound: the requested device has not been found
+#
+# @KVMMissingCap: the requested operation can't be fulfilled because a
+#                 required KVM capability is missing
