 * ``MAX_DISPATCH``: Maximum number of Virtual Machines actually dispatched to a host in each scheduling action (Default: 30)
 * ``MAX_HOST``: Maximum number of Virtual Machines dispatched to a given host in each scheduling action (Default: 1)
 * ``LIVE_RESCHEDS``: Rescheduling VMs performs migrations as ``1`` - live, ``0`` - cold.
-* ``COLD_MIGRATE_MODE``: Defines mode of cold VM migration. Options ``0`` - save, ``1`` - poweroff, ``2`` - poweroff hard. See :ref:`one.vm.migrate <one_vm_migrate>`.
+* ``COLD_MIGRATE_MODE``: Defines mode of cold VM migration. Options ``0`` - save, ``1`` - poweroff, ``2`` - poweroff hard. Please, note that parameter is taken into account for actions initiated by the scheduler but not users (e.g. migration commands instantiated by user from Sunstone or command line interface will ignore that parameter). See :ref:`one.vm.migrate <one_vm_migrate>`.
 * ``MEMORY_SYSTEM_DS_SCALE``: This factor scales the VM usage of the system DS with the memory size. This factor can be use to make the scheduler consider the overhead of checkpoint files (*system_ds_usage = system_ds_usage + memory_system_ds_scale * memory*).
 * ``DIFFERENT_VNETS``: When set (``YES``) the NICs of a VM will be forced to be in different Virtual Networks.
