I have compute servers with different CPU Speeds. How do I make it possible to launch an instance with a desired CPU speed (one among the servers' CPU's) ?

Do I understand correctly that you're asking how to make sure that some virtual instances run on specific type of hardware?

Nova scheduler has filters to decide compute node which has proper resource.

You can specify name of the compute node while launching a VM, using below CLI:

nova boot --image <uuid> --flavor m1.tiny --key_name <privatekey> --availability-zone nova:<name of="" the="" compute="" node="">

Also you can classify compute nodes to different host-aggregations which beloged to different availability zones. Then use nova boot command's field --availability-zone.
