When enabled the virtio-net-pci, guest network packet will load the vnet_hdr. In COLO status, the primary VM's network packet maybe redirect to another VM, it needs filter-redirect enable the vnet_hdr flag at the same time, COLO-proxy will correctly parse the original network packet. If have any misconfiguration here, the vnet_hdr_len is wrong for parse the packet, the data+offset will point to wrong place.
