I have multiple kinds of nic in cloud and want to configure SRIOV so instead of defining the following variable for each compute node, I would like to create a group and apply config to the groups. 

Am I right here to define groups like the following or is there a better way to handle this?

What is the default path of group_vars and hosts_vars in kolla-ansible? 

# vi /etc/kolla/group_vars/sriov_eno49.yml

neutron_sriov_physnet_mappings:
  physnet1: eno49 

# vi /etc/kolla/group_vars/sriov_eno50.yml

neutron_sriov_physnet_mappings:
  physnet1: eno50

# vi multinode

[sriov_eno49]
