Som emulator lar QEMU deg \u00e5 kj\u00f8re et program som er bygget for \u00e9n maskinvareplattform p\u00e5 et system med helt annen arkitektur, for eksempel \u00e5 kj\u00f8re en applikasjon for ARM p\u00e5 en x86-kompatibel PC. I virtualiseringsmodus er ytelsen til \u00e5 kj\u00f8re kode i et isolert milj\u00f8 n\u00e6r den native systemytelsen takket v\u00e6re direkte eksekvering av instruksjoner p\u00e5 CPU og bruk av hypervisor Xen eller KVM-modulen. <\/p>\n<p>Opprinnelig ble prosjektet opprettet av Fabrice Bellard for \u00e5 muliggj\u00f8re kj\u00f8ring av Linux-bin\u00e6rfiler kompillert for x86-plattformen p\u00e5 arkitekturer som er forskjellige fra x86. I l\u00f8pet av \u00e5rene med utvikling har st\u00f8tte for full emulering blitt lagt til for 14 maskinvarearkitekturer, og antallet emulerte maskinvareenheter har overstige 400. For versjon 5.0 ble det gjort over 2800 endringer fra 232 utviklere. <\/p>\n<p>N\u00f8kkelfunksjoner <noindex><a rel=\"nofollow\" href=\"http:\/\/wiki.qemu.org\/ChangeLog\/5.0\">forbedringer<\/a><\/noindex>, lagt til i QEMU 5.0: <\/p>\n<ul>\n<li class=\"l\"> Mulighet for \u00e5 videresende deler av vertsfilssystemet til gjestesystemet ved hjelp av <noindex><a rel=\"nofollow\" href=\"https:\/\/virtio-fs.gitlab.io\/\">virtiofsd<\/a><\/noindex>. Gjestemaskinen kan montere en katalog merket for eksport p\u00e5 vertsiden, noe som vesentlig forenkler organiseringen av felles tilgang til kataloger i virtualiseringssystemer.

The emulated 'virt' machines now support vTPM and virtio-iommu devices. The ability to use AArch32 host systems for running KVM guest environments has been deprecated. Emulation of the following architectural features has been implemented:\n<ul>\n<li> ARMv8.1: VHE, VMID16, PAN, PMU\n<li> ARMv8.2: UAO, DCPoP, ATS1E1, TTCNP\n<li> ARMv8.3: RCPC, CCIDX\n<li> ARMv8.4: PMU, RCPC\n<\/ul>\n<li class=\"l\"> I HPPA-arkitektur emulatoren er st\u00f8tte for grafisk konsoll med bruk av grafisk enhet HP Artist lagt til;\n<li class=\"l\"> I MIPS-arkitektur-emulatoren er st\u00f8tte for instruksjonen GINVT (Global Invalidation TLB) lagt til.\n<li class=\"l\"> The PowerPC architecture emulator has added the emulation of KVM hardware acceleration for running guest systems on 'powernv' machines;<br \/>\n KVM with a classic TCG (Tiny Code Generator). Support for NVDIMM reflected in the file has been added for emulating persistent memory. For 'pseries' machines, the need to reboot for synchronizing the operation of XIVE\/XICS interrupt controllers in &#171;ic-mode=dual&#187; has been removed;<\/p>\n<li class=\"l\"> The RISC-V architecture emulator for 'virt' and 'sifive_u' boards has implemented support for standard syscon drivers in Linux for power management and rebooting. Support for Goldfish RTC has been added for the 'virt' board. An experimental implementation of hypervisor extensions has been added;\n<li class=\"l\"> I emulatoren for s390-arkitektur er det lagt til st\u00f8tte for AIS (Adapter Interrupt Suppression) n\u00e5r
