The default security group already allow traffic between ports belonging to the same tenant, and this is apparently your case. If you've altered the default settings however, it might as well be that the security group is now blocking the traffic.</div>

Hi,<br>I am able to successfully spawn VMs on my single-node Grizzly setup on Ubuntu 13.04. I can ping from one VM to another VM. But i can't ping the internal router interface which resides on the same subnet as the VMs. I have not yet configured external network and gateway this router. NOTE: I can't ping to VMs from the host machine which I believe is because of router not configured with external interface.<br>
