Floating IPs seem disconnected

Hi,

I followed this guide and other multi-node GRE guides: https://github.com/josh-wrale/OpenStack-Folsom-Install-guide/blob/master/OpenStack_Folsom_Install_Guide_WebVersion.rst (https://github.com/josh-wrale/OpenSta...)

I'm on 12.10 with three nodes.. Control, network and compute. I have L3_agent and DHCP agent running on network node. Namespaces are enabled. My VM's can get a private DHCP address. However, when I create and associate a floating IP, it never seems to actually work.

I'm getting frustrated with the ERROR: No public addresses found for 'VM_NAME' response from nova ssh from an external host.

When I associate a floating IP with a VM, shouldn't nova list show the private IP, as well as the public IP? My VM's show no other IP than the primary private IP. And the floating IP isn't pingable from the general public network.

Dump of background info:

thanks for the detailed report. this looks like a bug, as you should see the floating IPs as additional ips on the interface qg-a62da873-41 in the following output in you log:

Can you see if there are errors in the log for the quantum-l3-agent?

Here's what I see after doing a cat '' > /var/log/l3_agent.log, then a reboot.

I think I'm going to rebuild...again.. This time, I'll try the new guide which was announced/revised(?) today: http://docs.openstack.org/folsom/basic-install/content/ (http://docs.openstack.org/folsom/basi...)

I've built my test environment in about ten different ways over the past month or two. At the end of every single one, I've run into problems. I suppose I could throw in the towel and retreat to nova-network and Essex, but I'd really rather just figure out what I'm doing wrong.

Thanks for the help. Here's to another failed install. lol
