Comment 1 for bug 1584209

This is probably only exclusive to using the octavia driver. I found this comment [1] in the code that I apparently wrote, but I don't totally remember the problem. I think in this particular case it's that if octavia is responsible for creating the VIP then it owns the VIP and octavia has to delete the load balancer to delete the port.

Testing this out real quick it looks like the vip_port_id gets populated when the allocates_vip option is False, which is what it is by default. Do you have this set to true in the config?
