Hi Eyle,
Once we faced  LACP issue with host-if interfaces. In our topology host-if
interfaces between two containers are connected via Linux bridge.
when one container is sending LACP PDU to another container those PDU's are
dropped by Linux.  Please enable the packet trace on both sides and check
whether LACP PDU's are exchanged or not between the interfaces.

Below reference might be useful to you.

Thanks and regards,
Sudhir
