Small update: in fact the tap interface exists, it's managed by OVS, and not shown by `ip a' command:
[root@undercloud log]# ovs-vsctl list-ports br-int int-br-ctlplane tap936f789b-55
I suspect an issue accessing to the openvswith socket - not sure though. Nothing seems to raise an error with that so far.
