I ran into some similar issues with the _enable_hairpin() call. The call is allowed to fail silently and (in my case) was failing. I couldn't for the life of me figure out why, though, and since I'm really not a networking person I didn't trace it along too far. Just thought I'd share my simila

Hi Jiaan, The problem may relates to SNAT iptables set by nova-network. Based on the description, I guess you have only one nova-network running on Controller. Please try: 1. add the following line to /etc/nova/nova.conf --mutil_host=true 2. start a nova-network instance on Compute Node service
