Hi all, I am facing this issue again,

I try to add this configuration but still, the node is going to compute1.

[scheduler]
driver = filter_scheduler
host_manager = host_manager

[filter_scheduler]
available_filters=nova.scheduler.filters.all_filters
enabled_filters=RetryFilter,AvailabilityZoneFilter,RamFilter,DiskFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter,CoreFilter
use_baremetal_filters=False
weight_classes=nova.scheduler.weights.all_weighers

[placement]
randomize_allocation_candidates = true

thank you.

Best Regards,
Zufar Dhiyaulhaq
