As suggested in another reply, look into colocation constraints. If you 
only use primitive resources (no clones or master/slave resources), you 
could also use a group instead of single resources. In fact, groups are 
just a syntax shortcut for colocation constraints between all resources 
within that group, but that happens in the background.
