Hi all,

We are using the release version of Diablo, and when we configure
multi-zone and we sent a new instance to run , we get this TRACE on the
nova-scheduler.log

(nova.rpc): TRACE: Traceback (most recent call last):

(nova.rpc): TRACE: SchedulerHostFilterNotFound: Scheduler Host Filter
nova.scheduler.filters.AllHostsFilter could not be found.
(nova.rpc): TRACE:


But the host filter file is there, we tried replicating the for validations
of the _get_filter fuction on host_filter.py , all is getting True for
AllHostsFilters but still getting that the filter is not found.

Any known issue ?

Best Regards!
