Hello,

lets say i have multiple compute nodes, Pool-A has 5 nodes and Pool-B has 4 nodes categorized based on some property. Now there is request for new instance, i always want this instance to be placed on any compute in Pool-A.
What would be best approach to address this situation?

FYI, this question is best asked on openstack@ ML. openstack-dev@ is for development questions.

You can use the AggregateInstanceExtraSpecsFilter and aggregate metadata to accomplish your needs.

Read more about that here:
