Description Keigo Noha 2022-10-18 07:16:36 UTC
Description of problem:
NovaLibvirtMaxQueues parameter is not properly propagated to nova::compute::libvirt::max_queues:

In the current implementation in OSP16.2, 

~~~
    908             if:
    909             - nova_libvirt_max_queues_set
    910             - nova::compute::libvirt::max_queues: {get_attr: [RoleParametersValue, value, nova_libvirt_max_queues]}
    911             - {}
~~~

However, nova_libvirt_max_queues is not defined in T-H-T.
I think we need to backport the following fixes.
https://review.opendev.org/c/openstack/tripleo-heat-templates/+/847530
https://review.opendev.org/c/openstack/tripleo-heat-templates/+/853808

Version-Release number of selected component (if applicable):
OSP16.2

How reproducible:
Every time

Steps to Reproduce:
1. Set NovaLibvirtMaxQueues to specific values, 8.
2. Deploy overcloud.
3. Confirm [libvirt] max_queues in nova.conf in nova-compute.

Actual results:

Just FYI, this is the deployment aspect of the following rhos-prio escalations's (https://bugzilla.redhat.com/show_bug.cgi?id=2135392) workaround.
