I am following this guide to deploy sriov compute with kolla-ansible (I am not using kayobe) - https://www.stackhpc.com/sriov-kayobe.html 

In the above doc last section neutron sriov agent, I am using the same code but those variables are not reflecting. It just prints everything as it is. 

# cat /etc/kolla/host_vars/os1-bos-sriov-comp-001.yml

# cat /etc/kayobe/kolla/config/neutron/sriov_agent.ini

{% raw %}
[sriov_nic]
physical_device_mappings = {% for dev, physnet in sriov_physnet_mappings.items() %}{{ (loop.index0 > 0)|ternary(',','') }}{{ physnet }}:{{ dev }}{% endfor %}
exclude_devices =
{% endraw %}

After running deploy it just prints the entire file as its in sriov_agent.ini file instead of proper values of variable. Does kolla-ansible support the above code?
