You can use groups for that, see in the Datacenter -> HA tab, there you 
can configure a group with only the two desired ones enabled. Add the 
group to your services and they will only migrate to nodes in the group.

with the "restricted" option set they never migrate to an node which 
isn't in the group. Whitout it they migrate to an non group member if 
every member oft the group failed.
