Could you please help to share whether this kind of event is sent by
neutron-server or neutron agent ? I searched neutron code
from [1][2] this means the agent itself need tell neutron server the
device(VIF) is up then neutron server will send notification
to nova through REST API and in turn consumed by compute node?
[1]
https://github.com/openstack/neutron/tree/master/neutron/notify_port_active_direct
[2]
https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/rpc.py#L264
I believe the neutron agent is the one that is getting (or polling) the
information from the underlying network backend when VIFs are plugged or
unplugged from a host, then route that information via RPC to the neutron
server which then sends an os-server-external-events request to the compute
REST API, which then routes the event information down to the nova-compute
host where the instance is currently running.
