Spolo\u010dnos\u0165 Microsoft predstavila projekt Hyperlight, ktor\u00fd vyv\u00edja hyperv\u00edzor ur\u010den\u00fd na integr\u00e1ciu do aplik\u00e1ci\u00ed s cie\u013eom izolovan\u00e9ho vykon\u00e1vania k\u00f3du, ktor\u00fd nie je d\u00f4veryhodn\u00fd alebo si vy\u017eaduje \u0161peci\u00e1lnu ochranu. Hyperv\u00edzor je navrhnut\u00fd ako zdie\u013ean\u00e1 kni\u017enica, ktor\u00e1 zabezpe\u010duje vykon\u00e1vanie jednotliv\u00fdch funkci\u00ed v \u013eahk\u00fdch virtu\u00e1lnych strojoch (micro-VM) a organizuje v\u00fdmenu \u00fadajov s t\u00fdmito funkciami. K\u00f3d projektu je nap\u00edsan\u00fd v jazyku Rust a \u0161\u00edri sa pod licenciou Apache 2.0. <\/p>\n

Pre izol\u00e1ciu na platforme Linux sa podporuje pou\u017e\u00edvanie hyperv\u00edzorov KVM a mshv (Microsoft Hypervisor v Azure Linux), a na platforme Windows \u2014 WHP (Windows Hypervisor Platform) a WSL2 (Windows Subsystem for Linux 2) s KVM.
