Public bug reported: The "enable_isolated_metadata = True" options tells DHCP agents that for each network under its care, a neutron-ns-metadata-proxy process should be spawned, regardless if it's isolated or not. This is fine for isolated networks (networks with no routers and no default gateways), but for networks which are connected to a router (for which the L3 agent spawns a separate neutron-ns-metadata-proxy which is attached to the router's namespace), 2 different metadata proxies are spawned. For these networks, the static routes which are pushed to each instance, letting it know where to search for the metadata-proxy, is not pushed and the proxy spawned from the DHCP agent is left unused.
The DHCP agent should know if the network it handles is isolated or not, and for non-isolated networks, no neutron-ns-metadata-proxy processes should spawn. ** Affects: neutron Importance: Undecided Assignee: John Schwarz (jschwarz) Status: In Progress ** Changed in: neutron Assignee: (unassigned) => John Schwarz (jschwarz) ** Changed in: neutron Status: New => In Progress -- You received this bug notification because you are a member of Yahoo!
