I believe if you rezise the instance to a flavor that has hw:cpu_policy=dedicated on it, you should be good.
It worked! Thanks again :)

[Please note: This e-mail is from an EXTERNAL e-mail address] Thank you, Thiago! I managed to create an instance with dedicated cores, after application-apply. Btw, do we need to recreate all instances or is there a solution for existing instances which were created without dedicated cores?

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.

Hi Thiago,
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.

Hi Danishka,
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$>

[Please note: This e-mail is from an EXTERNAL e-mail address] Hi,
Is the cpu_dedicated_set is already enabled in stx based openstack? How to verify and enable it?
