I installed openstack:havana based on Havana (2014-03-18) and I used CentOS 6.4 as per the requirement. Now I am stuck with the following ERROR;

[root@controller nova]# nova network-create vmnet --fixed-range-v4= --bridge=br100 --multi-host=T
ERROR: The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-b3d5c917-95f2-432c-bae3-7a44569fde7a)

I googled and could not find a proper solution for this ERROR..

I have documented the dialog, system response and logs in for this complete installation until the ERROR occurred.

Did you run packstack --allinone ?
If "yes" , then source admin credenthials and try to run:
$ neutron net-llist
$ neutron net-create ext1 --router:external=True

Thanks for the quick response. I am not using packstack, I am following havana (2014-03-18) document with 2 nodes. (controller & compute)

make sure you have installed and runing memcached on both (controller, compute) nodes, also is it possible to ping one from each other using hostnames. I had the same issue, and after above operations it works fine for me. If you didn't fix it yet pls give an output of openstack-status from both nodes.

I would suggest you to perform Two Node cluster setup on CentOS 6.4 per Andrew Law. You may view
1. Andrew's blog
2.My blog
for step by step detailed instructions. Both setups Neutron OVS&VLAN had been done via prepared answer-files.
Not manually. They allow inbound connectivity. Original answer file was written by Andrew. Mine is a bit different, it doesn't require 3 Ethernet cards on Controller, just 2 for Controller and 2 for Compute nodes running CentOS 6.5 , what allows native Qemu work directly with glusterfs 3.4.2 volumes. I am expecting notice , that I am not answering your question and it would be correct notice. However, I prefer to drive a new car instead of old good bicycle.

Hi Boris, Thanks for your suggestion. I would like to prefer to continue with same procedure given on that document (havana 2014-03-18). Because I almost beginning of launch an instance. So, I would appreciate if anyone could help me to resolve the issue.
