<div>Hi all, I'm trying to set up OpenStack using
PackStack in a single node configuration, and I
believe I'm having some network issues. I think I've
narrowed the problem down to a forwarding issue, i.e.
the packets meant for 192.168.32.x (Pack Stack default
fixed address) aren't being routed correctly. When I
tcpdump br100 and try and ping my vm, all that shows
up are ARP requests, like:<br>
<br>
16:55:52.216132 ARP, Request who-has 192.168.32.2 tell
192.168.32.1, length 28<br>

Did your instance actually got this address (192.168.32.2)? I
assume it didn't since if it doesn't answer to arp so it couldn't
communicate with the dhcp server.<br>
I would start with the following:<br>

Sorry, it might get ip and still not answer arp in case the arp is
for address differs from what it got.<br>

Verify that 192.168.32.2 is the instance address (run "nova
list"), sometimes the second address of the network belongs to the
dhcp server.<br>
2. Verify that the instance gets its private IP, if not, set it
manually just for debugging.<br>
3. Flush iptables in the compute node and inside the instance's os
(run "iptables -F" and verify that the chains are on ACCEPT).<br>
4. Ping the instance and run tcpdump from inside the instance
("tcpdump -i any -s 0 arp -nn").<br>

My public interface is eth0, with addresses
192.168.0.xxx, and my flat interface is lo (loopback).
I've been following the directions on the site to the
letter and it still fails. Does anyone have any
suggestions as to what the problem is and how I can
solve it? I've pasted some information below, and I
can follow up with more as needed. Thanks.<br>
