Re: [Openstack] metadata issue

Wed, 13 Feb 2013 08:03:20 -0800

First of all, make sure metadata is DNAT'd to nova-api on your nova-network node.
For that, please issue 'iptables -t nat -S' and look at the corresponding entry :

-A nova-network-PREROUTING -d 169.254.169.254/32 -p tcp -m tcp --dport 80 -j DNAT --to-destination <ip>:8775

If this is correct, make sure nova-api is running on port 8775 on the nova-api node :
$ sudo lsof -i :8775
COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
nova-api 2130 nova    8u  IPv4  19784      0t0  TCP *:8775 (LISTEN)


Also, make sure you can establish a TCP connection in between network node and api node by running (on the network node):
telnet <api_host> 8775

I ran that command on compute node. I am using nova-network and flatdhcpmanager. 

I have another setup which has quantam . Having difficulties with the same problem in quantam.

HI :)
do you use nova-network or quantum? And according to the model you use, which kind? For instance vlan, flat, flatDHP for nova-network ? 
thanks,

Hi,

I have two nodes. A controller node and a compute. Both has 2 nics , eth0 is public and eth1 is private with no ip on it.  Compute node has nova-network and nova-compute . nova-api runs on both servers. I can see br100 up in compute node.

Thanks in advance.
Paras.

Hi,

The packages I am using are from folsom ubuntu quantal branch.  When I
run an instance I see

--
wget: can't connect to remote host (169.254.169.254): Network is unreachable
--

this might be the network issue as well.

nova list shows my instance .  I am running nova-network on compute
node. nova-api is running on both controller and compute nodes.

I have seen lot of ppl are having issues on this but i was not able to
find out the issue by looking at their posts.

How do I start debugging?

Thanks
Paras.
