La soci\u00e9t\u00e9 Microsoft pr\u00e9sent\u00e9e<\/a><\/noindex> Pour discussion sur la liste de diffusion des d\u00e9veloppeurs du noyau Linux, une s\u00e9rie de patchs a \u00e9t\u00e9 propos\u00e9e pour faire fonctionner l'hyperviseur Hyper-V avec un environnement racine bas\u00e9 sur Linux ayant un acc\u00e8s direct au mat\u00e9riel et utilis\u00e9 pour ex\u00e9cuter des syst\u00e8mes invit\u00e9s (similaire \u00e0 Dom0 dans Xen). Jusqu'\u00e0 pr\u00e9sent, Hyper-V (Microsoft Hypervisor) ne supportait Linux que dans des environnements invit\u00e9s, tandis que l'hyperviseur lui-m\u00eame \u00e9tait g\u00e9r\u00e9 \u00e0 partir d'un environnement Windows. Microsoft pr\u00e9voit maintenant de cr\u00e9er une pile compl\u00e8te de virtualisation avec Linux et Hyper-V. <\/p>\n

L'organisation du fonctionnement de l'hyperviseur dans les noyaux Linux et Windows diff\u00e8re consid\u00e9rablement, c'est pourquoi une approche diff\u00e9rente est adopt\u00e9e pour la configuration des sous-syst\u00e8mes et l'organisation des hyperappels dans l'impl\u00e9mentation de Hyper-V pour Linux. Le code pour le mapping des interruptions utilisant IOMMU a \u00e9t\u00e9 r\u00e9vis\u00e9 de mani\u00e8re analogue au code de support de Xen dans Linux (Xen et Hyper-V ont une architecture<\/a><\/noindex> similaire<\/a><\/noindex> et reposent sur l'utilisation d'un environnement privil\u00e9gi\u00e9 racine\/Dom0 pour la gestion).<\/p>\n

Les patches incluent une impl\u00e9mentation minimale n\u00e9cessaire au fonctionnement, propos\u00e9e comme prototype initial pour discussion et critique. Pour g\u00e9rer l'hyperviseur, un dispositif \/dev\/mshv est sugg\u00e9r\u00e9, gr\u00e2ce auquel des applications de l'espace utilisateur peuvent cr\u00e9er et ex\u00e9cuter des machines virtuelles. Un port d'hyperviseur de haut niveau a \u00e9galement \u00e9t\u00e9 propos\u00e9 Cloud Hypervisor<\/a><\/noindex>, permettant de d\u00e9marrer des machines virtuelles sur Hyper-V au lieu de KVM. <\/p>\n

En 2018, le nombre de syst\u00e8mes invit\u00e9s sous Linux dans le service cloud Azure a d\u00e9pass\u00e9<\/a><\/noindex> bas\u00e9 sur Windows, dont la part diminue constamment, principalement gr\u00e2ce \u00e0 la mont\u00e9e en popularit\u00e9 des plateformes devops et de Kubernetes, qui sont li\u00e9es \u00e0 Linux. L'utilisation d'une pile unique bas\u00e9e sur Linux pourrait potentiellement simplifier la maintenance et am\u00e9liorer la performance des serveurs Hyper-V g\u00e9rant des syst\u00e8mes invit\u00e9s sous Linux.<\/p>\n
