I have installed the latest version of openstack newton and have setup all the services required for it on a single node setup, I would be able to launch the instance and access it via ssh soon after it is booted up. But the issue is after a few seconds the instance wont be accessible via public IP and our ssh session would be logged out.

I have tried it with cirros and centos images and both have produced the same result. What could be wrong in this scenario ?

Are you using Open vSwitch or a Linux bridge, or what? You could use tcpdump to packet capture the relevant interfaces whilst this is occurring, and you could also check the relevant logs.

It is Linuxbridge. I set up tcpdump on the tap device used by the instance and then attach a floating ip from web UI. I see traffic flowing for a few seconds after which there is no further traffic in/out of this tap device. Why is this happening?
