Hi OSA Experts,

I'm trying to bring up openstack using openstack-ansible in AIO flavor by having neutron ml2 plugin set to ovs.
OSA is being executed from OPNFV XCI deployer with attached openstack_user_config and user_variables*.yml files.
I can see installation [1] is being successful, but not able to boot nova VMs and VxLAN tunnel is not established between compute (vm) and neutron-agents container (inside the same vm).

Here are the observations:

  1.  Timeout errors occur continuously in neutron-openvswitch-agent.log of the compute vm. It looks like this happens while accessing rpc for agent report status [2] .

Increasing rpc_response_timeout to 180 sec and restarting openvswich-agent, l3, dhcp and neutron-server service also doesn't help.

Here is the neutron-openvswitch-agent.log [3] and neutron agent-list CLI shows empty output. There is no weird errors in rabbitmq log.

  1.  Nova boot fails with "The requested availability zone is not available" error and corresponding error logs in neutron-server.log  [4].
  2.  On the compute vm, vxlan port is not created on the br-tun bridge and neutron-agents container doesn't have br-tun bridge itself [5].

Please have a look and let me know if you need more details.
