Hi All,

I have installed OpenStack on ubuntu 14.04 and follow the steps by Geek Everything is fine but the IP is wired. I cut my network, but when I launch a cirros I can't ping it. I have set All ICMP, SSH, HTTP into security rules, and I can use the VM by dashboard. 1. But the IP in dashboard shows, and in console is 2. I can't ping both IP.

Here is the VM log

=== cirros: current=0.3.2 uptime=1.14 === === pinging gateway failed, debugging connection === ############ debug start ##############

Un-comment public-interface=br100 and flat-network-bridge=br100. Problem solved. Thanks.
