+# @ColoCompareProperties:
+#
+# Properties for colo-compare objects.
+#
+# @primary_in: name of the character device backend to use for the primary
+#              input (incoming packets are redirected to @outdev)
+#
+# @secondary_in: name of the character device backend to use for secondary
+#                input (incoming packets are only compared to the input on
+#                @primary_in and then dropped)
+#
+# @outdev: name of the character device backend to use for output
+#
+# @iothread: name of the iothread to run in
+#
+# @notify_dev: name of the character device backend to be used to communicate
+#              with the remote colo-frame (only for Xen COLO)
+#
+# @compare_timeout: the maximum time to hold a packet from @primary_in for
+#                   comparison with an incoming packet on @secondary_in in
+#                   milliseconds (default: 3000)
+#
+# @expired_scan_cycle: the interval at which colo-compare checks whether
+#                      packets from @primary have timed out, in milliseconds
+#                      (default: 3000)
+#
+# @max_queue_size: the maximum number of packets to keep in the queue for
+#                  comparing with incoming packets from @secondary_in.  If the
+#                  queue is full and addtional packets are received, the
+#                  addtional packets are dropped. (default: 1024)
+#
+# @vnet_hdr_support: if true, vnet header support is enabled (default: false)
+#
+# Since: 2.8
