Public bug reported:
When instances are booting, they will try to retrieve metadata from
Nova by the path of Neutron virtual switches(bridges), virtual devices,
namespaces and metadata-agents. After that, metadata agent has no other
functionalities. In large-scale scenarios, a large number of deployed
metadata agents will cause a waste of resources for hosts and message queue.
Because they will start tons of external processes based on the number of
users' resources, report state to Neutron server for heartbeat keepalive.
How many metadata-agent should run for a large scale cloud deployment?
There is no exact answer to this question. Cloud operators may setup
metadata agent to all hosts, something like DHCP agent. Config drive can be
an alternative for clouds to supply metadata for VMs. But what if users do
not want to add a cd-rom device to VM?
So, I'd like to request for implementing an agent extension for Neutron
openvswitch agent to make the metadata datapath distributed.
