Hi,

Which network mode do you use ?
I think I get the same problem in VLAN network mode. Can you check your
'nova-api' logs ?

The DNAT rule in pre-routing table change the destination of meta data
packets but SNAT rule in post routing table change the source IP of all
outgoing traffic.
So, the meta data handler cannot identify the origin of the meta data
request. The flag 'use_forwarded_for' permit to use the HTTP header field
'X-Forwarded-For' tio identify the IP source of the meta data request.
But I don't know how configure 'cloud-init' to set this HTTP header ?

Doude.
