To Reproduce:
Configure the image properties weigher to use os_version or os_admin_user.
[zuul@controller ~]$ oc exec nova-scheduler-0 -- cat /etc/nova/nova.conf.d/02-nova-override.conf [filter_scheduler] image_props_weight_setting = hw_cpu_threads=2, hw_cpu_policy=10, os_secure_boot=3, os_admin_user=5' image_props_weight_multiplier = 10000.0
Update image(s) to use those properties:
sh-5.1$ openstack image set fff1d34a-9bd5-4116-ba6e-6f447ed97692 --property os_secure_boot=optional --property os_admin_user=rootsh-5.1$ openstack server create --image fff1d34a-9bd5-4116-ba6e-6f447ed97692 --flavor m1.micro --network public osprh-19466-01 --wait
Schedule multiple guests with the above image:
sh-5.1$ openstack server create --image fff1d34a-9bd5-4116-ba6e-6f447ed97692 --flavor m1.micro --network public osprh-19466-01 --wait sh-5.1$ openstack server create --image fff1d34a-9bd5-4116-ba6e-6f447ed97692 --flavor m1.micro --network public osprh-19466-02 --wait
Monitor the raw weights in this example os_secure_boot is being taking into consideration but not os_admin_user:

Expected behavior
- os_admin_user and os_version are taken into consideration as part of the raw weights
