Hello,
I am setting up a 3-node icehouse testbed on RHEL6.5, using RDO, the
testbed has one controller node, one network node and one compute node.
I use ML2 plugin, with OVS
mechanism and VLAN type.
When I start an instance, it fails. On the compute node nova.log file,
there is the following error messages:

On the controller node and network node, I don't see much errors from
the neutron services log files. I can connect to the (standalone) DB
from the network node, using the username/password inside the
neutron.conf file.
Here are the relevant rpms on the compute node:

Any idea what went wrong?
Thanks a lot,
