Title (EN) PROTECTING MEMORY OF A VIRTUAL GUEST
(FR) PROTECTION DE LA MÉMOIRE D'UN CLIENT VIRTUEL
Abstract: front page image
(EN)The method for protecting memory of a virtual guest includes initializing a virtual guest on a host computing system. The host computing system includes a virtual machine manager that manages operation of the virtual guest. The virtual guest includes a distinct operating environment executing in a virtual operation platform provided by the virtual machine manager. The method includes receiving an allocation of run-time memory for the virtual guest, the allocation of run-time memory comprising a portion of run-time memory of the host computing system. The method includes setting, by the virtual guest, at least a portion of the allocation of run-time memory to be inaccessible by the virtual machine manager.
(FR)L'invention concerne un procédé de protection de la mémoire d'un client virtuel, qui comprend les étapes suivantes : initialiser un client virtuel sur un système informatique hôte, ledit système comprenant un gestionnaire de machine virtuelle qui gère le fonctionnement du client virtuel, ledit client virtuel comprenant un environnement d'exploitation distinct exécuté dans une plate-forme de commande virtuelle fournie par le gestionnaire de machine virtuelle ; recevoir une affectation de mémoire d'exécution destinée au client virtuel, ladite affectation de mémoire d'exécution comprenant une partie de la mémoire d'exécution du système informatique hôte ; faire régler, par le client virtuel, au moins une partie de l'affectation de mémoire d'exécution afin que celle-ci soit inaccessible au gestionnaire de machine virtuelle.
