I have seen some docs that indicate that you can launch an instance on a specific compute host. Does anybody know how to properly structure the cli request ? I have tried with this

 --availability-zone= 
--hint force_hosts=
somthing like 
nova boot --image 79ced6dd-a9a1-4843-9e38-a4337228adb6  --flavor m1.windows --nic net-id=9a2a3961-9afd-4cb2-940f-3a8e5badb82a --hint force_hosts=host1  testhost

Would appriciate any help i can get

According to the OpenStack Admin User Guide you should be able to use 

 nova boot --image <uuid> --flavor m1.tiny --key_name test --availability-zone nova:server2

to get list of available hypervisor, use:

nova hypervisor-list

You can use Host Aggregates for that, i had a similar problem here is a link with the solution that worked for me https://ask.openstack.org/en/question/120253/selecting-compute-node-to-deploy-an-instance/ (https://ask.openstack.org/en/question...)
