Hi All, I am using centos 6.4 (virtual machine installed on ESX server) to install open stack (devstack),with single node setup(All in one).

Centos on which open stack is installed have only one NIC card. (eht0).
 1. I install neutron service to this setup, 
 2.created public and private network , and routed them together following instruction given in user guide.
 3.added security rules to pas tcp/icmp traffic to the instance, and added keypair to ssh it from outer world.
 4. assigned private and public (floating ip) to the open stack instance (cirros).

what i found is, i am unable to ping the instance (with both private and floating ip) from centos on which open stack is installed, neither i can ssh to it as it ends with error message 'no route to the host'

My question is i sit because of single nic card (eth0) present on my centos causing me this issue..?
Is there any workaround for this problem..?

Any feedback will be very helpful.

I'm not sure about the dev-stack. I have done installation on Single NIC and made it work. I have just written(half complete) article on "Strategy for OpenStack Installation". I'm yet to put the complete details of configuration etc. Hopefully it will complete in another to days. I'm confident that dev-stack will not be something different. Since I have not tried on dev-stack, i'm not able to comment. You can visit this page see this half written article.

Is it because network namespace issue..? As i am using centos 6.4 + devstack setup.And found that it does not support network namespace required for smooth working of open stack neutron service.

Yes. It does require namespace. Did you check whether your kernel supports it ? Also did you install dkms package on your box ?
