Question about the scheduler

My cluster is consisted:

from the two types of the DS:
a) ImageDS_ceph, SystemDS_ceph (TM_MAD = ceph)
b) ImageDS_ssh, SystemDS_ssh (TM_MAD = ssh)

the common pool of the hosts:
a) with small disk partition for deploy VM in SystemDS_ceph and prepared for work with Ceph
b) with large disk partition for deploy VM in SystemDS_ssh

For now any an image from ImageDS_ssh can deployed on any host of the cluster.

Have existed some way to restrict deploy VM for the scheduler: for image from ImageDS_ssh to deploy only on the hosts (b) with large disk partition?

Except usage the Scheduling in the template of VM.

Thank you for your help.
