If I remember correctly, when a user makes a reservation request, that request is assigned to a particular computer id. This determination depends on which resources a particular user has access to (image groups, computer groups, management node groups, etc), and on which computers may have that image preloaded. From the computerid, vcld determines which management node handles that request and also which vm host controls that particular computer.
