Open Stack

Hi,

I am deploying a openstack cluster with several compute nodes
on CentOS 6.4 with Neutron/Quantum and network_type vlan based on
these guides:

http://docs.openstack.org/trunk/openstack-network/admin/content/under_the_hood_openvswitch.html

https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst

http://openstack.redhat.com/Neutron_with_OVS_and_VLANs

In my setup I have a "controller" that runs everything plus additional
compute
nodes (and I plan to remove the compute service from the controller).

I have had an issue with reaching guest VM instances when they are spawned
on compute nodes other the controller and discovered that while the
l3-agent deployed on the controller was added to the router, adding
the other l3 agents, e.g.

 quantum l3-agent-router-add 789a77fd-52ff-44be-afea-27d26a8cd3d3 router01

 resulted in the following error displayed in the openvswitch log:

2013-09-04 19:44:24    ERROR [quantum.api.v2.resource] create failed
Traceback (most recent call last):

789a77fd-52ff-44be-afea-27d26a8cd3d3.


Could anyone help me by pointing to its cause? I've filed a bug on this,
there are more details in its description:

Thanks,
