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

+------------+--------------------------------------------------------------------------------------------------------+

| Field      | Value
                                          |

+------------+--------------------------------------------------------------------------------------------------------+

| properties | hw:cpu_cores='2', hw:cpu_policy='dedicated',
hw:cpu_sockets='1', hw:cpu_threads='2', hw:numa_nodes='1' |

+------------+--------------------------------------------------------------------------------------------------------+


Regards,

Danishka
