Don't get metadata from nova-api

Hey Guys,

i'm using UEC image with ubuntu 11.10.
If i run an instance i get every time

DataSourceEc2.py[WARNING]: 'http://169.254.169.254' failed: url error [time out].
I tried with other DMZ-Host (pub-ip) and other my_ip-Flag in nova.conf, but it wasn't successfully.

The Nova-Api are reachable on a public and internal interface (pub and private net).
All Services are distributed, so i have a server for nova-api, DB, compute. On each compute node runs a network-manager too.

I've studied the tcpdump and the routing logs, and i see the this request above have no route (no really working route) to the api.

Btw. i can ping each started instance!
