OpenStack: Why Horizon and CLI don't show updated resources after the CPU overcommitment procedure?

Question

I configured nova.conf file with:
cpu_allocation_ratio=16.0
ram_allocation_ratio=1.5
specifying CoreFilter in scheduler_default_filters.
After this configuration i can't see the overcommitment results in the CLI or in Horizon.
Why? Any tips?

Comments

I discovered that:
"The Compute API always returns the actual number of CPU cores available on a compute node regardless of the value of the cpu_allocation_ratio configuration key. As a result changes to the cpu_allocation_ratio are not reflected via the command line clients or the dashboard. Changes to this configuration key are only taken into account internally in the scheduler."
