Hi!

What we‘ve got in our small public cloud:

 

scheduler_default_filters=AggregateInstanceExtraSpecsFilter,

AggregateImagePropertiesIsolation,

RetryFilter,

AvailabilityZoneFilter,

AggregateRamFilter,

AggregateDiskFilter,

AggregateCoreFilter,

ComputeFilter,

ImagePropertiesFilter,

ServerGroupAntiAffinityFilter,

ServerGroupAffinityFilter

 

#ComputeCapabilitiesFilter off because of conflict with AggregateInstanceExtraSpecFilter https://bugs.launchpad.net/nova/+bug/1279719

 

I really like to set resource limits using Aggregate metadata.

Also, Windows host isolation is done using image metadata. I have filled a bug somewhere that it does not work correctly with Boot from Volume. I believe it got pretty much ignored. That’s why we also use flavor metadata.

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).
