F\u00f8rste offentlige version af Multikernel Linux-projektet (mklinux-v7.0-mk2) er blevet pr\u00e6senteret. Dette projekt udvikler en variant af Linux-kernen, der giver mulighed for at k\u00f8re flere uafh\u00e6ngige instanser af kernen p\u00e5 \u00e9n fysisk computer uden brug af hypervisorer og virtualisering. Hver instans af kernen har direkte adgang til hardwareressourcerne og kan anvendes til at k\u00f8re separate isolerede systemmilj\u00f8er. Den f\u00f8rste version er baseret p\u00e5 Linux-kernen 7.0 og indeholder byggeindstillingen CONFIG_MULTIKERNEL; n\u00e5r denne deaktiveres, bliver kernen helt identisk med standardkernen 7.0. Af CPU-arkitekturer underst\u00f8ttes der indtil videre kun x86_64. <\/p>\n

Multikernel pr\u00e6senteres som en ny isolationsmekanisme, der indtager en niche mellem virtualisering via en hypervisor og containerbaseret isolering baseret p\u00e5 en f\u00e6lles kerne. I mods\u00e6tning til virtualisering kr\u00e6ver Multikernel ikke brug af en hypervisor, hvilket forenkler oprettelsen af milj\u00f8er til isoleret k\u00f8rsel af enkelte applikationer og muligg\u00f8r h\u00f8j ydeevne uden overhead fra virtualisering. I mods\u00e6tning til containere giver Multikernel et h\u00f8jt isolationsniveau og tillader brug af en separat kerne i hvert isoleret milj\u00f8, hvor et crash eller udnyttelse af en s\u00e5rbarhed ikke p\u00e5virker andre milj\u00f8er.

<\/center> <\/p>\n

V\u00e6rt-kernen sikrer fordelingen af tilg\u00e6ngelige CPU'er, hukommelse og PCI-enheder mellem de parallelt fungerende ekstra kerneinstanser. Hver instans k\u00f8rer p\u00e5 en dedikeret CPU-kerne, arbejder med de tilknyttede enheder og har adgang til et dedikeret omr\u00e5de af fysisk hukommelse. Samtidig k\u00f8rsel af flere kerner udf\u00f8res uden virtualisering ved hj\u00e6lp af en SMP-h\u00e5ndtering, der fordeler de tilg\u00e6ngelige CPU'er. Dynamisk ressourceallokering til de k\u00f8rende milj\u00f8er underst\u00f8ttes, og der sikres forudsigelig ydeevne. <\/p>\n

Takket v\u00e6re udelukkelsen af de typiske virtualiseringsomkostninger vurderes ydeevnen ved brug af Multikernel at v\u00e6re t\u00e6t p\u00e5 ydeevnen ved udf\u00f8relse p\u00e5 separat hardware. N\u00e5r man bruger Multikernel, er der ikke noget kontroloverf\u00f8rsel mellem virtuelle maskiner (VM exit), der anvendes ikke sider fra andet niveau, en separat enhedsmodel og overs\u00e6ttelse af IOMMU. Sammenlignet med hypervisoren KVM<\/a> Ved brug af Multikernel observeres en stigning i ydeevnen for forskellige systemopkald og funktioner fra 1,07 til 2,5 gange (fork + exit - 1,07x, write() - 1,39x, AF_UNIX - 1,55x, Pipe - 2,18x, kontekstskift - 2,50x), og b\u00e5ndbredde og forsinkelse ved arbejde med hukommelse forbliver p\u00e5 samme niveau.
