Bug 1413248

The misunderstanding is that we are not using neutron-ovs-dpdk.yaml..this is not the case.
This The default neutron-ovs-dpdk.yaml values can be overridden in network-environment.yaml file created the confusion.

My suggestion is this line need to be replaced:
The parameters inside the environment file neutron-ovs-dpdk.yaml's has to be overridden to the actual compute-host values.

This will solve the issue.

You are correct, documentation will be updated once we will verify this by deployment, but you have another option:

See A.2.6, for now it is on overclod_deploy.sh
A.2.6. overcloud_deploy.sh

#!/bin/bash

cat >"$HOME/extra_env.yaml"<<EOF
---
parameter_defaults:
    Debug: true
EOF

openstack overcloud deploy --debug \
--templates \
--environment-file "$HOME/extra_env.yaml" \
--libvirt-type kvm \
--ntp-server clock.redhat.com \
-e /home/stack/<relative-directory>/network-environment.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/neutron-ovs-dpdk.yaml \
--log-file overcloud_install.log &> overcloud_install.log

You are correct

Yariv, once this has been tested, can you let me know of the changes that need to be included either to the 'network-environment.yaml' file or the 'openstack overcloud deploy' command in the NFV Config guide.

Changing assignee to rhos-docs list. Lucy to reassign the bug when there is more to go on.

Hi Maxim Sandra

Once it is verified we have to update 10.z docs

Hi Sandra,

I have verified the config change.

Please, set the following line to the network-environment.yaml file:

OS::TripleO::Services::ComputeNeutronOvsAgent: /usr/share/openstack-tripleo-heat-templates/puppet/services/neutron-ovs-dpdk-agent.yaml

And remove the following line from the overcloud_deploy.sh script.

-e /usr/share/openstack-tripleo-heat-templates/environments/neutron-ovs-dpdk.yaml \

Thanks,
Maxim.

Maxim, I dont understand the reason for removing the environment file and using it directly, Can you eloborate the reason behind it?

Plese refer to the upstream documentation - http://tripleo.org/advanced_deployment/ovs_dpdk_config.html

Note: It is just a reference, all upstream configuration are not same as OSP10.

Saravanan,

In composable roles mixed environment - dpdk, sriov, we are specifying the features within the network-envirnment as the following.

  OS::TripleO::Services::ComputeNeutronOvsDpdkAgent: /usr/share/openstack-tripleo-heat-templates/puppet/services/neutron-ovs-dpdk-agent.yaml
  OS::TripleO::Services::NeutronSriovAgent: /usr/share/openstack-tripleo-heat-templates/puppet/services/neutron-sriov-agent.yaml

I think it might be a good practice to use it in all scenarios in order to keep the same base config for the templates.

ComputeNeutronOvsDpdkAgent is used for adding a new role specific for DPDK, as per earlier discussion, we are not using a new role. We will use only Compute to enable it with DPDK. Also if you are using ComputeNeutronOvsDpdkAgent, the corresponding roles_data.yaml also should be added. I guess, I have to wait for the documentation draft to conclude on it.

These are the proposed changes to section 3.1 in the NFV Configuration guide:

https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/10/html/network_functions_virtualization_configuration_guide/part-dpdk-configure#configure_ovs_dpdk_in_red_hat_openstack_platform


Step 1b. Set the ComputNeutronOvsAgent to use the neutron-ovs-dpdk-agent.yaml file. Add the following line under resource_registry::

resource_registry:
OS::TripleO::Services::ComputeNeutronOvsAgent: /usr/share/openstack-tripleo-heat-templates/puppet/services/neutron-ovs-dpdk-agent.yaml

Note: Configure the values in neutron-ovs-dpdk-agent.yaml to match your environment.


....

Step 4. Run the overcloud_deploy.sh script to deploy your overcloud with OVS-DPDK:

# openstack overcloud deploy --templates \
--libvirt-type kvm \
--ntp-server clock.redhat.com \
-e /home/stack/<relative-directory>/network-environment.yaml

The /home/stack/<relative directory>/network-environment.yaml sets the path for the network-environment.yaml file.

I will also update the sample yaml file for ovs-dpdk with the same details.  Let me know if this is correct.

Sandra,

No changes should be made to the above.
