Public bug reported:
For stable/stein
Honestly, I do not sure this is bug or something that I am missing. At
least it lacks of information so I report this.
When segment firstly set for a subnet, Neutron are trying to make 'host
aggregate' in nova, 'resource provider' in placement, and add host to
'host aggregate'
I found when Neutorn add 'host' to 'host aggregate', the 'host' is came
'ironic node uuid' from networking-baremetal. But the problem is nova
deos not know the 'host' since only thing that nova knows is host from
ironic-nova-compute rather thant 'ironic node uuid'
>From neutron/services/segments/plugin.py _create_nova_inventory(),
self.n_client.aggregates.add_host(aggregate.id, mapping.host)
Nova emit the exception like below

Is it okay to ask Nova to register ironic node uuid for host aggregate?
Thanks.
