[Launchpad Bug Tracker <1674257@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

When nova used ironic driver， there was an exception which was always
logged in nova compute log fie periodically. The
update_available_resource method calls the  _get_host_metrics method to
cause this problem. In ironic driver , the get_host_cpu_stats method is
not implemented. so we should not log the exception message to eliminate
misunderstanding. The cycle logged message is as follows.

So, I want to ignore the unimplemented excepion in the '_update_data'  method in virt_driver.py.

** Affects: nova
     Importance: Undecided
         Status: New

-- 
we should not log  unimplemented error in _get_host_metrics method
