Title:
[master] metadata is not working on multi-node setup
Status in devstack:
New
Status in neutron:
New
Bug description:
Setup:
1. One controller
2. KVM and ESX nova compute
3. Two Network nodes running q-dhcp and q-meta
Nodes: Ubuntu 14.04.3 amd64 Trusty
On above setup, tried to run few metadata queries we see 500 internal
server error.
$ route -n
Kernel IP routing table

$ curl http://169.254.169.254
500 Internal Server Error
Remote metadata server experienced an internal server error.

NOTE: Moved all services to single node(controller) and metadata
queries seems to work fine.
