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:
16:55:52.216132 ARP, Request who-has 192.168.32.2 tell 192.168.32.1,
length 28
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.
I would start with the following:
Sorry, it might get ip and still not answer arp in case the arp is for
address differs from what it got.
1. 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.
2. Verify that the instance gets its private IP, if not, set it
manually just for debugging.
3. Flush iptables in the compute node and inside the instance's os
(run "iptables -F" and verify that the chains are on ACCEPT).
4. Ping the instance and run tcpdump from inside the instance
("tcpdump -i any -s 0 arp -nn").
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.
