cannot ping OpenStack launch instance

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 10.134.12.208/28, 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 10.134.12.210, and in console is 10.134.12.201. 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 ===
