The devstack is installed and one KVM guest starts, both the host and guest are using ubuntu 12.04 image.

But the cloud-init in guest can't get meta-data from the host. The iptables rule in host looks correct and also saw packets are re-directed, port 80 is re-directed to port 8775, and nova-api is listening 8775 port.

How to solve this problem?

In the guest

cloud-init start-local running: Wed, 05 Jun 2013 03:51:02 +0000. up 2.88 seconds no instance data found in start-local ci-info: lo : 1 . ci-info: eth0 : 1 fa:16:3e:47:d9:f6 ci-info: route-0: eth0 UG ci-info: route-1: eth0 U cloud-init start running: Wed, 05 Jun 2013 03:51:03 +0000. up 3.31 seconds 2013-06-05 03:51:53,284 -[WARNING]: '' failed [50/120s]: url error [timed out] 2013-06-05 03:52:44,336 -[WARNING]: '' failed [101/120s]: url error [timed out] 2013-06-05 03:53:02,355 -[WARNING]: '' failed [119/120s]: url error [timed out] 2013-06-05 03:53:03,357 -[CRITICAL]: giving up on md after 120 seconds

In the host

#netstat -lntp | grep 8775

tcp 0 0* LISTEN 29763/python

iptables before guest starts:

22 1320 DNAT tcp -- any any anywhere tcp dpt:http to:

iptables after guest starts:

39 2340 DNAT tcp -- any any anywhere tcp dpt:http to:

tcpdump host -i br100

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on br100, link-type EN10MB (Ethernet), capture size 65535 bytes

Are you using Quantum? If you are Quantum relays the route to the metadata server via DHCP. You have to configure it using /etc/quantum/dhcp_agent.ini, follow to get the metadata service working.

I had the same issue. In my case, the instance was not able to reach the gateway. In fact, i never had setup one. It resolved by setting up the gateway.

As a first step, ping your gateway. In this case. If you are using quantum networking. You have to make use "ip netns" to reach the gateways for each namespace.
