Title:
Nova/Placement creating x86 trait for ARM Compute node
Status in OpenStack Compute (nova):
Fix Released
Bug description:
Description
===========
I have a 2023.2 based deployment with both x84 and aarch64 based compute
nodes. For the arm node, placement is showing it having an x86 HW trait,
causing scheduling of arm architecture images onto it to fail. It also causes
it to try and schedule x86 images onto here, which will fail.
Steps to reproduce
==================
1. I deployed a new 2023.2 deployment with Kolla-ansible.
2. Add hw_architecture=aarch64 to a valid glance image
3. Ensure that image_metadata_prefilter = True in nova.conf on all nova
services
4. Try and deploy an instance with that image, it will fail with no valid
host found
5. Observe the following in the placement-api logs:

I have tried to run openstack resource provider trait delete

nova_compute on this compute node, however the same traits come back.
