Subject: Re: [Openstack] Filter Scheduler options implemented by default

Hi, Atul

You are right, If you just put
> compute_scheduler_driver = nova.scheduler.filter_scheduler.FilterScheduler
in nova.conf. And not explicitly set 'scheduler_default_filters', it's value will be ['RetryFilter', …,'ImagePropertiesFilter'] default.

So all your host should pass these Filters.

Best regards,
Adir Gao
