Multi-scheduler was there for the days when Nova has to deal with both request for instance and volume. If you are using a version of Nova which still has nova-volume, I think multi-scheduler is a must. And there are two sub config option for Nova: http://docs.openstack.org/folsom/openstack-compute/admin/content/ch_scheduling.html scheduler_driver=nova.scheduler.multi.MultiScheduler volume_scheduler_driver=nova.scheduler.chance.ChanceScheduler compute_scheduler_driver=nova.scheduler.filter_scheduler.FilterScheduler But if you are using trunk version Nova, scheduler_driver should use 'nova.scheduler.filter_scheduler.FilterScheduler' directly.
