Thanks Jay.

After enable debug, I found the scheduler fails at
ComputeCapabilitiesFilter step.
Recall the filter chain I configured is

scheduler_default_filters=RetryFilter,AggregateInstanceExtraSpecsFilter,AvailabilityZoneFilter,RamFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter

Now I'm researching why it fails at that filter.
