Did you do an application-apply after you changed the processors to application-isolated? Can you send the output of the command below for you compute pods:
kubectl exec -n openstack nova-compute-[woker|controller]-X-XXXXX-xxxx -- cat /etc/nova/nova.conf|grep dedicated_set
Don't forget to change the id of the pod for your compute pods.

I have configured the worker as mentioned in the given link and dedicated cpu_policy set in the flavor. Instance creation failed with the following error.
No valid host was found. There are not enough hosts available.

Whatever you configure on the platform as Application-isolated core for a node will get to cpu_dedicated_set on stx-openstack. Please check this doc: https://docs.starlingx.io/r/stx.5.0/admintasks/openstack/configure-dedicated...https://urldefense.com/v3/__https://docs.starlingx.io/r/stx.5.0/admintasks/openstack/configure-dedicated-and-shared-cpu-pools-on-hosts.html__;!!AjveYdw8EvQ!Km5xOEiy_wI3YAmney4OpHhqwjOOCiNhB37qanNSizdNpERIM_eDDRfwAzNuQv9j-Hlr$

Hi,
Is the cpu_dedicated_set is already enabled in stx based openstack? How to verify and enable it?
