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.

controller-0:~$ openstack flavor show dn.large  -c properties

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-and-shared-cpu-pools-on-hosts.html

Hi,

Is the cpu_dedicated_set is already enabled in stx based openstack?

How to verify and enable it?
