Hi everyone,

I have configured openstack Havana on ubutu server 12.04. I have a three
server a controller, a compute and a network node. I have used neutron for
networking with openvswitch. I can deply and run an instance. But i can't
ping the floatting ip associated with the instance. I added icmp and ssh
rules. I added also gre for INPUT and OUTPUT into iptables. I have also
verified my ovs and neutron configurations, they are as mentioenned in the
openstack havana docs. This is my network configurations: for compute node:

root at compute:~# ip a
