isolated metadata in dhcp_agent.ini

[Andrey Grebennikov]

I suggest to turn on the option "enable_isolated_metadata=true" in dhcp_agent.ini of Neutron.

It will allow automatically create provider network and preserve metadata functionality.

This needs to be changed to "true" in neutron/lib/puppet/parser/functions/sanitize_neutron_config.rb

I think an options like 'isolated matadata', 'l2_population' should be configurable from UI.
In the settings tab we should create Neutron section and put these checkboxes here.

I confirm that with "enable_isolated_metadata=false" isolated network cannot contact the metadata agent. This means that VMs not attached to a vrouter cannot receive metadata (e.g., keypair and cloud-init configuration) and definitely compromise the VM usability. This is a not a good behavior, so I suggest to set the default value to true.

Does it make sense to make possibility of change the values Sergey provided earlier through UI?

[Andrey Grebennikov (agrebennikov)]

I'd say no. The way it works is that if the network doesn't have a virt rourer created - neutron creates metadata listeners in the dhcp namespace. If there is a router - it will be resided in the router's namespace. That's why I'd suggest to persistently turn it on.
