摘要

TO DETERMINE WHETHER TO DEPLOY A CANDIDATE VM (12) TO A CANDIDATE HOST (14), TAKING INTO CONSIDERATION RESOURCES AVAILABLE FROM THE CANDIDATE HOST AND RESOURCES REQUIRED BY THE CANDIDATE VM, A SUB-RATING IS CALCULATED FOR EACH OF SEVERAL RESOURCES AVAILABLE FROM THE CANDIDATE HOST (411), WHERE THE SUB-RATING FOR THE RESOURCE CORRESPONDS TO AN AMOUNT OF THE RESOURCE THAT IS FREE AFTER THE CANDIDATE VM IS DEPLOYED TO THE CANDIDATE HOST. THEREAFTER, A RATING IS CALCULATED (413) FROM THE CALCULATED SUB-RATINGS TO CHARACTERIZE HOW WELL THE CANDIDATE HOST CAN ACCOMMODATE THE CANDIDATE VM. THE RATING FOR THE CANDIDATE HOST ARE PRESENTED (415) TO A SELECTOR THAT DETERMINES WHETHER TO DEPLOY THE CANDIDATE VM (12) TO THE CANDIDATE HOST (14) BASED ON THE RATING THEREOF.
