I disagree. If one of these filters is filtering out a host, it's for a good reason.
Feel free to bring this up on the openstack-dev list. ** Tags added: scheduler ** Changed in: nova Status: New => Won't Fix -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1184622 Title: Change scheduler_default_filters to AllHostsFilter in host_manager.py Status in OpenStack Compute (Nova): Won't Fix Bug description: Currently in OpenStack nova, if did not set scheduler_default_filters, then it will use default values as following: cfg.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.'), And customer often encounter error as "No valid host" because one of the above filters failed during scheduling, it is better that we change the default value to AllHostsFilter, this can make sure scheduler can always succeed.
