Mirantis nova: Can we modify quotas in instance from the default infinite(-1) value set by fuel?

Asked by Danny

The limit to the number of instances launched in mirantis nova is set to infinite(-1). Can we change this value to say set the quotas as 100?

On giving the below command:
nova quota-update --instances 100 c525392fa9bf4ebaad54b6769c39ffe5

This was the error thrown:
ERROR (ClientException): The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-bceb9d66-74be-4e5f-9704-5621deaeb223)

Hello Dhanvi,
in order to set quotas, you have to enable them, either by enabling the checkbox 'Nova quotas' in the Fuel settings pane (before a deployment), or by editing nova.conf and substituting

quota_driver=nova.quota.NoopQuotaDriver

with

quota_driver=nova.quota.DbQuotaDriver

and finally restarting all the nova services.

Best regards,
