Thanks Ben.
After adding sbrec_port_binding_add_clause_type(&pb, OVSDB_F_EQ,
"localnet"); in the update_sb_monitors() function, the patch ports for
localnet can be created,
but that is very confused when debugging the program, initially this
hypervisor is set as the gateway chassis where other vms spawned in other
hypervisor can go dnat_and_snat
through this node that without any vm spawned. In the begginging the patch
ports are created successfully, then I booted two vms, assigned
floatiingips, they are not recheable, so I begin to do ofproto/trace,
during that time, the patch ports suddenly deleted and can't be created
well. The GDB showed that no localnet type binding can be found from ovn sb
idl, I
am not quite understand the ovn sb idl update/monitor logistic so far.
Anyway probably my environment is messed up, I have re-create the
environment and try to do again.
