Thank you mark, i think you found my typo :)  that was it.

How do i group nodes and pass configuration to specific group like.
for example i have GPU and IB compute nodes. i want to group them so i
can push out to config to GPU group related GPU and IB (infiniband)
related IB config

[gpu]
1.1.1.1
2.2.2.2
3.3.3.3

[ib]
4.4.4.4
5.5.5.5
6.6.6.6

[compute:children]
gpu
ib

Can i apply config like following for group related?  what is the best
way to handle groups in kolla-ansible?

/etc/kolla/config/nova/gpu/nova.conf
/etc/kolla/config/nova/ib/nova.conf
