Public bug reported: Description =========== Performing rebuild of a vm with a different image passes when the images have different cpu_threads_policy defined in image metadata, when it should fail
Steps to reproduce
==================
1. Create two images, one with hw_cpu_threads_policy=prefer and other
hw_cpu_threads_policy=isolate
2. create a flavor with 2 cpus, make sure Compute host has at least 4 physical
cpus, and following metadata:
hw:cpu_policy='dedicated'
3. create a vm with first image
4. Rebuild the vm with the second image. It passes here when it should be
failing
Expected result
===============
Rebuild fails with below error:
An instance's NUMA topology cannot be changed as part of a rebuild. The image
provided is invalid for this instance. (HTTP 400)
Actual result
=============
(overcloud) [stack@undercloud-0 ~]$ openstack image set --property
hw_cpu_threads_policy='prefer' rhel7.7
(overcloud) [stack@undercloud-0 ~]$ openstack image set --property
hw_cpu_threads_policy='isolate' rhel8.1
