We have the following enabled on our semi-public (academic community)
cloud, which runs on Newton:

AggregateInstanceExtraSpecsFilter
AvailabilityZoneFilter
ComputeCapabilitiesFilter
ComputeFilter
ImagePropertiesFilter
PciPassthroughFilter
RamFilter
RetryFilter
ServerGroupAffinityFilter
ServerGroupAntiAffinityFilter

(sorted alphabetically) Recently we've also been trying

AggregateImagePropertiesIsolation

...but it looks like we'll replace it with our own because it's a bit
awkward to use for our purpose (scheduling Windows instance to licensed
compute nodes).
