I usually separate things using host aggregate feature.

In my deployment, I have 2 different nova pools. So, in nova.conf, I define
the *images_rbd_pool* variable point to desired pool and then, I create an
aggregate and put these computes into it. The flavor extra_spec metadata
will define which aggregate the instance will be scheduled.
