Hi All, I wanted help regarding the nova scheduler options. If i am not passing any options inside my nova.conf apart from compute_scheduler_driver = nova.scheduler.filter_scheduler.FilterScheduler As per the default options https://github.com/openstack/nova/blob/master/nova/scheduler/host_manager.py#L32 (thanks garyk) will all these filter rules will be processed fg.ListOpt('scheduler_default_filters', default=[ 'RetryFilter', 'AvailabilityZoneFilter', 'RamFilter', 'ComputeFilter', 'ComputeCapabilitiesFilter', 'ImagePropertiesFilter' ], help='Which filter class names to use for filtering hosts ' 'when not specified in the request.'), Let me know if am understanding it correctly. So by default my all host will go through all above filtering types. :) Thanks!! Atul Jha http://www.csscorp.com/common/email-disclaimer.php
