'Openstack Cirros instance cannot ping or resolve Internet hosts
I have deployed RDO Openstack Xena on Virtual Box. There were no errors in the installation. Created external network another network named blue and attached it to a router. I defined 8.8.8.8 as DNS. Everything looks fine but when I create Cirros instance, this instance cannot ping outside the Internet. Floating IP has been defined. The second Cirros instance has the same issue as well.
Any help is much appreciated.

Most probably, you need to revise the Security Group assigned to the instance. Ensure you have an Egress rule like this.
If two cirros instances can ping the internal ip (not the floating) one another but can not ping the public (floating) ip, then the problem is that you need a router between the internal network and the public network.
