Or, the virtual machine runs on a traditional operating system, and the same hardware-simulated instance is created, which is called a hosted or hosted type. Alternatively, the virtual machine runs on a traditional operating system and creates a separate virtualized instance (container) that points to the underlying managed operating system and is referred to as "operating system virtualization.” The most common one is still the bare-machine hypervisor. The virtualization kernel is installed directly on the hardware computing resources. The virtual machine and its GuestOS are installed and run on top of the hypervisor.

Abstract

L'invention concerne un procédé pour mettre en œuvre un appel d'application et une machine virtuelle. Le procédé consiste : à acquérir, par une machine virtuelle, des informations concernant des attributs d'une icône de raccourci spécifiée ; à créer, par la machine virtuelle, une icône de raccourci d'une application correspondant à l'icône de raccourci spécifiée sur un bureau virtuel ; et lorsque la machine virtuelle reçoit une instruction pour déclencher l'icône de raccourci sur le bureau virtuel, à exécuter une application locale qui correspond à l'icône de raccourci et est installée sur un terminal. Le procédé de la solution technique de la présente invention fournit une solution technique pour établir rapidement une liaison souple de raccourci de programme d'application entre le bureau virtuel et un utilisateur de terminal local, de telle sorte que l'objectif de démarrage direct d'un programme d'application locale du terminal dans le bureau virtuel est atteint, et une commutation répétée entre le bureau virtuel et un bureau local du terminal n'est pas nécessaire, permettant ainsi d'améliorer considérablement la facilité d'utilisation et la commodité d'utilisateurs de bureau, et, en outre, d'améliorer le niveau d'automatisation du bureau virtuel en ce qui concerne les aspects de l'exploitation et de l'utilisation.
