Hi Nick,

Check your scheduler configurations in the /etc/nova/nova.conf in the
controller node. Some scheduler configurations I use are as below:

 scheduler_available_filters=nova.scheduler.filters.all_filters

scheduler_default_filters=AvailabilityZoneFilter,CoreFilter,RamFilter,ComputeFilter,RetryFilter

compute_scheduler_driver=nova.scheduler.filter_scheduler.FilterScheduler

scheduler_max_attempts=3

cpu_allocation_ratio=1.5

ram_allocation_ratio=1.0

The allocation rations and type of filters may vary depending on your needs.

Regards,
Balu
