Yes, you need to use host aggregates. You would put the ironic compute hosts into an aggregate, and all of the other compute hosts into another, and then have the extra_specs in the flavor set to whichever aggregate you want the instance to go to. This can definitely get a little tricky with the networking if you're using overlays, since Ironic can't really attach a hardware node to a software managed L2 network, but you can just make sure users understand which networks will be available on which flavors and that should work. _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
