Som emulator giver QEMU mulighed for at k\u00f8re programmer, der er bygget til \u00e9n hardwareplatform, p\u00e5 en system med en helt anden arkitektur, for eksempel ved at k\u00f8re en ARM-applikation p\u00e5 en x86-kompatibel PC. I virtualiseringstilstand er kodek\u00f8rselens ydeevne i et isoleret milj\u00f8 t\u00e6t p\u00e5 hardware-systemets takket v\u00e6re direkte udf\u00f8relse af instruktioner p\u00e5 CPU'en og brug af hypervisoren Xen eller KVM-modulet.       <\/p>\n<p>Projektet blev oprindeligt skabt af Fabrice Bellard med det form\u00e5l at muligg\u00f8re k\u00f8rsel af eksekverbare filer i Linux, der er bygget til x86-platformen, p\u00e5 arkitekturer, der adskiller sig fra x86. Gennem \u00e5rene er der blevet tilf\u00f8jet fuld emulering for 14 hardwarearkitekturer, og antallet af emulerede hardware-enheder har overskredet 400. I forberedelsen af version 8.0 er der blevet foretaget over 2800 \u00e6ndringer af 238 udviklere.     <\/p>\n<p>N\u00f8gleforbedringer i QEMU 8.0:   <\/p>\n<ul>\n<li class=\"l\"> St\u00f8tte til systememulering (k\u00f8rsel af hele OS, inklusive brug af hypervisorer og Xen) p\u00e5 32-bit v\u00e6rter med x86-arkitektur erkl\u00e6res for\u00e6ldet og vil snart blive oph\u00f8rt.
