Som en emulator lar QEMU deg kj\u00f8re programmer som er kompilert for \u00e9n maskinvareplattform p\u00e5 et system med en helt annen arkitektur, for eksempel \u00e5 kj\u00f8re en applikasjon for ARM p\u00e5 en x86-kompatibel PC. I virtualiseringsmodus er ytelsen til kodekj\u00f8ring i en isolert milj\u00f8 n\u00e6r den fysiske maskinens ytelse takket v\u00e6re direkte utf\u00f8relse av instruksjoner p\u00e5 CPU-en og bruk av hypervisoren Xen eller KVM-modulen.       <\/p>\n<p>Prosjektet ble opprinnelig opprettet av Fabrice Bellard med det form\u00e5l \u00e5 gj\u00f8re det mulig \u00e5 kj\u00f8re Linux-kj\u00f8rbare filer kompilert for x86-plattformen p\u00e5 arkitekturer som er forskjellige fra x86. Gjennom \u00e5rene har det blitt lagt til st\u00f8tte for full emulering for 14 maskinvarearkitekturer, og antallet emulerte maskinvareenheter har overskredet 400. I forberedelsen av versjon 8.0 er det gjort over 2800 endringer fra 238 utviklere.     <\/p>\n<p>N\u00f8kkelforbedringer lagt til QEMU 8.0:   <\/p>\n<ul>\n<li class=\"l\"> St\u00f8tte for systememulering (kj\u00f8ring av hele OS, inkludert med hypervisorer) p\u00e5 32-biters vertsdatamaskiner med x86-arkitektur er erkl\u00e6rt foreldet og vil snart bli avsluttet. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/no\/vps\/abuzoustojchivye-vps\/\"   title=\"KVM\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"4421\">KVM<\/a> St\u00f8tten for emulering i user-mode (kj\u00f8ring av individuelle prosesser, kompilert for en annen CPU) p\u00e5 32-biters x86-vertsmaskiner vil bli opprettholdt.\n<li class=\"l\"> I x86-emulatoren er det lagt til st\u00f8tte for \u00e5 kj\u00f8re gjesteoperativsystemer Xen i et milj\u00f8 basert p\u00e5 hypervisoren KVM og Linux 5.12+.\n<li class=\"l\"> I den klassiske TCG-kodegeneratoren for x86-arkitektur er CPUID-flaggene FSRM, FZRM, FSRS og FSRC n\u00e5 st\u00f8ttet.
