I am trying to install openstack using the instructions given in this link http://docs.openstack.org/juno/instal...

I am not able to ping the subnet from my controller node. I have a three node setup, all of which are virtual machines with single nics. I am running these VMs on VMware workstation. On my controller node, I can see that all the agents are active, as mentioned in the document. On the network node, I have 3 namespaces, a router namespace and two dhcp namespaces. The setup is as follows image description I can ping the gateway to the external net from router namspace. I can also ping the subnet interface from router. However, I am not able to ping the subnet (192.168.1.1) from controller. Neither could I ping controller from router.

The output of 'ip a' is at http://paste.openstack.org/show/178514 The output of 'ovs-vsctl show' is at http://paste.openstack.org/show/178515

Can someone help me fix this issue?

Whats your ICMP rule, make sure it's not disabled, Check Access- Security Tab

You have

Port "qr-5c5e935c-c9"
            tag: 4095
            Interface "qr-5c5e935c-c9"
                type: internal

4095 is dead tag Try recreate external network ( qrouter-namespace)

Same problem

Port "tapec6b9c5f-e1"
            tag: 4095
            Interface "tapec6b9c5f-e1"

Which tap-interface is this ? It's not working due to same reason tag=4095

As far as I see 192.168.43.0/24 is your external network, which is actually vmware subnet.

Please place VMWare vSwitch ( or whatever the bridge is called) in promiscuous mode
I want to see iptables statement on box hosting VMWare Hypervisor MASQUERADE subnet 192.168.43.0/24

What means this entry ?

Interface "gre-7f000001"
                type: gre
                options: {df_default="true", in_key=flow, local_ip="192.168.43.132", out_key=flow, remote_ip="127.0.0.1"}

Please, post it as a separate question. Describe your base OS ( it was CentOS 7 I guess) && Openstack version installed, method of install , one node or multinode. In any case post ovs-vstcl show and ifconfig on Network Node.
