Environment: Centos6.5+RDO+havana

I create a instace successfully with (public ip:192.168.226.101,private ip:10.10.10.2). I can ping private ip but I can't ping public ip.  I found following information from my dashboard. status of 192.xxx.xxx.xxx are DOWN, status of 10.xx.xx.xx are Active. I'm a newer for openstack.could some help to tell me the solution? or you can tell me how to debug this issue?

Hi dbaxps,

security rule was added when I create network.

Please provide :-
$ neutron router-list
$ ip netns | grep router_id ( for every router)
$ ip netns exec qrouter-router_id iptables -S -t nat
$ ip netns exec qrouter-router_id ip a
$ ip netns exec qrouter-router_id ifconfig
$ ovs-vsctl show
and upload to some text file on Internet or make archive.

$ ip netns exec qrouter-router_id ifconfig will provide for instance
qg-9c090153-08
qr-e031db6b-d0
In ovs-vsctl tree should be corresponding interface entries for 9c090153-08 under br-ex
and for e031db6b-d0 under br-int.
My intend is to run tcpdump -i inteface-name -vv on each one of mentioned interfaces
when you try to ping VM floating IP from Controller and see could we capture anything at internal and external interfaces

OK. I just took a look at your security group list in my mail box . Nothing has been done. It should look like :-

Hi dbaxps,

    When I install my lab. I name the eth0 to ech0. I have to use it in br-ex.  following is the information you wanted. seems flooating ip(192.xxxx) is not activated.
    cat /etc/sysconfig/network-scripts/ifcfg-eth0

     Add the security rules

     $ neutron security-group-rule-create --protocol icmp  --direction ingress --remote-ip-prefix 0.0.0.0/0 default
     $ neutron security-group-rule-create --protocol tcp   --port-range-min 22 --port-range-max 22  --direction ingress    --remote-ip-prefix 0.0.0.0/0  default

  Or add security rules via dashboard :

Add security rules for ICMP and TCP

Per your feedback (ovs-vsctl show) :-

Bridge br-ex
Port br-ex
Interface br-ex
type: internal
Port "ech0"
Interface "ech0"
Port "qg-df4f9361-a1"
Interface "qg-df4f9361-a1"
type: internal

Hence Interface "eth0" is not attached to OVS port "eth0" of OVS bridge br-ex.
Such configuration of ovs-vsctl show is not supposed to work
Say "xxxxxxxxxx" your router-id then command
$ ip netns exec qrouter-xxxxxxxxx tcpdump -ln -i qg-df4f9361-a1
won't capture any ICMP request from yours AIO Havana Server

Now I need
$ ip netns | grep router_id , coming from neutron router-list and output for :-
$ ip netns exec qrouter-router_id ifconfig ( for router namespace , where your VM is running )

What means interface "ech0" should "eth0" ?
Can you explain ?

Without output I've asked , would try :-
tcpdump -i qr-3055a9a8-40 -vv
tcpdump -i qr-a6a7d763-50 -vv
tcpdump -i qg-df4f9361-a1 -vv
when pinging VM from Controller.

Another option to troubleshoot :

Say 4cdb0354-7732-4d8f-a3d0-9fbc4b93a62d is your router-id
Then run :-
ip netns exec qrouter-4cdb0354-7732-4d8f-a3d0-9fbc4b93a62d tcpdump -ln -i qg-df4f9361-a1
ip netns exec qrouter-4cdb0354-7732-4d8f-a3d0-9fbc4b93a62d tcpdump -ln -i qr-3055a9a8-40
ip netns exec qrouter-4cdb0354-7732-4d8f-a3d0-9fbc4b93a62d tcpdump -ln -i qr-a6a7d763-50 

The only one qr-xxxxx will come up running
ip netns exec qrouter-4cdb0354-7732-4d8f-a3d0-9fbc4b93a62d ip a

Can you run :-
$ ip netns list
Right now . I want to see your qrouter-* namespaces.
