We discussed this on IRC today [1]. In short, we realize that this was a change in behaviour introduced in Liberty that should have been better discussed at the time. However, Liberty was many years ago and it's genuinely debatable whether this was ever intended behaviour, let alone something we'd want to reintroduce support for.
Having discussed this, we're going to document this change in behaviour in the docs and leave it there. If this (support for arbitrary image metadata properties in this filter) is something you still see value in, we'd probably have to treat it as a new feature. I'd encourage you to file a spec [2] so we can evaluate the idea. If not, hopefully the documentation change helps clarify things.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1741810 Title: Filter AggregateImagePropertiesIsolation doesn't Work Status in OpenStack Compute (nova): Won't Fix Bug description: Description =========== I tried to use filter AggregateImagePropertiesIsolation to isolate Windows instance for reducing number of Windows Licenses. I think nova scheduler in pike release, filter AggregateImagePropertiesIsolation always returned all hosts. If this is a bug, filter AggregateImagePropertiesIsolation needs to be fixed. Steps to reproduce ================== # add filter to nova.conf and restart nova scheduler [filter_scheduler] enabled_filters = AggregateImagePropertiesIsolation,RetryFilter,AvailabilityZoneFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter # image create with os property openstack image create --min-disk 3 --min-ram 512 --disk-format qcow2 --public --file windows.img img_windows openstack image create --min-disk 1 --min-ram 64 --disk-format qcow2 --public --file cirros-0.3.5-x86_64-disk.img img_linux openstack image set --property os=windows img_windows openstack image set --property os=linux img_linux # host aggregate create with os property openstack aggregate create os_win openstack aggregate add host os_win compute01 openstack aggregate add host os_win compute02 openstack aggregate set --property os=windows os_win openstack aggregate create os_linux openstack aggregate add host os_linux compute03 openstack aggregate add host os_linux compute04 openstack aggregate add host os_linux compute05 openstack aggregate set --property os=linux os_linux # create flavor openstack flavor create --ram 1024 --disk 1 --vcpus 1 --public small openstack flavor create --ram 4096 --disk 20 --vcpus 2 --public medium # create windows instances openstack server create --image img_windows --network test-net --flavor medium --max 10 test-win Expected result =============== Windows instances can be found in compute01, compute02 only Actual result ============= Windows instance was found in every hosts.
