Title (EN) SYSTEMS AND METHODS FOR CONTROLLING, BY A HYPERVISOR, ACCESS TO PHYSICAL RESOURCES
(FR) SYSTÈMES ET PROCÉDÉS POUR GÉRER L'ACCÈS À DES RESSOURCES PHYSIQUES AU MOYEN D'UN HYPERVISEUR
Abstract:
(EN) A system for controlling, by a hypervisor, access to physical resources during execution of a virtual machine includes a physical disk and a hypervisor. The physical disk is provided by a computing device and stores at least a portion of a virtual disk. The hypervisor executes on the computing device. The hypervisor allocates, to the virtual disk, an amount of access to the physical disk. The hypervisor determines that a level of utilization of the physical disk has exceeded a threshold. The hypervisor limits, in response to the determination, access by the virtual disk to the physical disk.
(FR) La présente invention concerne un système permettant de gérer, au moyen d'un hyperviseur, l'accès à des ressources physiques pendant l'exécution d'une machine virtuelle, le système comprenant un disque physique et un hyperviseur. Le disque physique, qui est mis en œuvre par un dispositif informatique, sert de support à au moins une partie d'un disque virtuel. L'hyperviseur s'exécute sur le dispositif informatique. L'hyperviseur affecte au disque virtuel une quantité d'accès au disque physique. Lorsque l'hyperviseur constate qu'un niveau d'utilisation du disque physique a dépassé un seuil, il réagit en limitant l'accès du disque virtuel au disque physique.
