ACRN assure ainsi des latences r\u00e9duites et une r\u00e9activit\u00e9 ad\u00e9quate lors des interactions avec le mat\u00e9riel. La virtualisation des ressources CPU, des entr\u00e9es\/sorties, des sous-syst\u00e8mes r\u00e9seau, ainsi que des op\u00e9rations graphiques et sonores est prise en charge.
