[Openstack] Weird Network problem
Hi! I am performing a new installation of openstack-icehouse on a CentOS 6.5 machine (all-in-one). I have configured a FlatDHCP nova network and I can start succesfully a cirrOS instance. Moreover, I can ping it (10.0.0.2) and I can ssh to it without any problems. The problem is that although I can resolve a hosts name (eg. www.google.com) from inside the instance I cannot ping it. It seems as if I cannot go outside my master host from inside that instance. The same thing happens if I provide a floating-ip to the instance. I can ping and ssh to the floating IP but if I ssh into the instance I cannot reach the outside world. Any ideas???
