Greetings,

First we recommend to review nova-schedule.log to see if you have any tracebacks related to any Scheduler class(es). If so please post details here and we'll be happy to review them.

Detailed information on filters: http://docs.openstack.org/trunk/config-reference/content/scheduler-filters.html

Please note that various filters may not work how you think they would work. For example, there is no VMWare DRS equivalent in OpenStack, for allocation based dynamically on resources availability.

Filters are binary - a host is either accepted or rejected by the filter. Accepted hosts are then processed using a Weights algorithm. The RamWeigher is the only weigher currently available.

Hope this helps. Please let us know if you find specific bugs with specific Filters and we'll be happy to help with lodging a bug report regarding the matter.
