Hello out there
I'm stuck with neutron not starting any dnsmasq processes after upgrading neutron to the queens release (yes I know this is an elderly version ;)) Details:
I see errors from neutron-dhcp-agent (on the dhcp host and on the controller node for the neutron-rpc-server): ValueError: Unrecognized attribute(s) 'binding:host_id'
But I'm pretty sure this is a followup of the directory /var/lib/neutron/dhcp ($state_path) beeing almost empty (only empty directories named by the networks beeing there, which are rebuild by the neutron-dhcp-agent if deleted).
I'm further do not see any ports in the DB for dhcp. Which eventually explains why the state files for dnsmasq are missing.
So now I'm stuck: - Which agent/daemon should create the ports for the dnsmasq process ?
The installation should launch two dhcp processes on two router nodes (HA setup). Which is also correctly shown using neutron dhcp-agent-list-hosting-net which shows two dhcp-agents up and running !
Any hints how to solve are appreciated !
Greetings
