Openstack Juno: Cannot ping instances with IP other than 10.0.0.2
I have installed Openstack Juno. I have created two Cirros instances with private IPs 10.0.0.2 and 10.0.0.4, respectively. Both the instances are connected to a network 10.0.0.0, which is in turn connected to router. The router is then connected to public network(172.24.4.0).
I have created a Security Group in which I have added appropriate rules for allowing ICMP (both ingress and egress). I can successfully ping the instance having IP 10.0.0.2 from the machine on which devstack is installed.
But, I cannot ping the instance having IP 10.0.0.4. I have made sure that both the instances have the same Security Group.
In short, I cannot ping any instance with IP other than 10.0.0.2. What could be the reason for that?
Please help me resolve the problem.
Per my understanding security group rules gets modified for particular tenant ( project ) , rather then for particular VM. I suspect your VMs belong to different tenants. In general ( I am not Devstack user ) private IPs are ping able only inside corresponding qdhcp-namespaces
