Kao emulator, QEMU omogu\u0107ava pokretanje programa sastavljenih za jednu hardversku platformu na sustavu s potpuno druga\u010dijom arhitekturom, na primjer, izvr\u0161avanje aplikacije za ARM na PC-u kompatibilnom s x86. U na\u010dinu virtualizacije, performanse izvr\u0161avanja koda u izoliranom okru\u017eenju blizu su hardverskog sustava zahvaljuju\u0107i izravnom izvr\u0161avanju instrukcija na CPU-u i uklju\u010divanju hipervizora Xen ili modula KVM u Linuxu, ili modula NVMM u NetBSD.    <\/p>\n<p>Projekt je prvotno stvorio Fabrice Bellard s ciljem omogu\u0107avanja izvr\u0161avanja izvr\u0161nih datoteka Linuxa sastavljenih za x86 platformu na arhitekturama koje se razlikuju od x86. Tijekom godina razvoja dodana je podr\u0161ka za potpunu emulaciju za 14 hardverskih arhitektura, a broj emuliranih hardverskih ure\u0111aja prema\u0161io je 400. Prilikom pripreme verzije 11.0.0 napravljeno je vi\u0161e od 2500 promjena od strane 237 programera.     <\/p>\n<p>Klju\u010dna pobolj\u0161anja dodana u QEMU 11.0:   <\/p>\n<ul>\n<li class=\"l\"> Ukidanje podr\u0161ke za 32-bitne host-sustave, koja je progla\u0161ena zastarjelom u travnju pro\u0161le godine s QEMU 10.0. U izdanju 10.2 u prosincu prekinuta je podr\u0161ka za platforme mips32 i ppc32 u generatoru koda TCG (Tiny Code Generator), dok su u izdanju QEMU 11.0 uklonjene preostale platforme i386, arm, ppc i riscv32, a tako\u0111er je izvr\u0161eno \u010di\u0161\u0107enje koda i sustava gradnje od komponenti za rad na 32-bitnim hostovima.\n<li class=\"l\"> Implementirana je ubrziva\u010d virtualizacije \u00abnitro\u00bb (\u00ab-accel nitor\u00bb) i nova vrsta emuliranih sustava \u00abnitro\u00bb koji omogu\u0107uju pokretanje izoliranih enklava na temelju tehnologije povjerljivog ra\u010dunanja AWS Nitro Enclave u QEMU, npr. za lokalno testiranje Nitro Enclave okru\u017eenja u QEMU. U AWS EC2, tehnologija Nitro Enclave omogu\u0107ava pokretanje ugra\u0111enih izoliranih enklava u virtualnoj ma\u0161ini za rad s povjerljivim podacima, dodjeljuju\u0107i im dio svojih resursa.\n<li class=\"l\"> Pobolj\u0161ana podr\u0161ka za akceleratore virtualizacije MSHV (Microsoft Hypervisor) i WHPX (Pro\u0161irenja Microsoft Windows Hypervisor Platform).\n<li class=\"l\"> Prilikom kori\u0161tenja hipervizora KVM (\u00ab-accel kvm\u00bb) omogu\u0107ena je podr\u0161ka za virtualizaciju Intel CET (Control-flow Enforcement Technology) za primjenu u <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/hr\/vps\/abuzoustojchivye-vps\/\"   title=\"virtualnim ma\u0161inama\" data-wpil-keyword-link=\"linked\">virtualnim ma\u0161inama<\/a> za\u0161titi od eksploita koji koriste metode povratno-orijentiranog programiranja (ROP \u2014 Return-Oriented Programming).

Podr\u0161ka za DRM kontekste uklju\u010duje se prilikom kori\u0161tenja novog ure\u0111aja virtio-gpu-gl s opcijom \u00abdrm_native_context=on\u00bb. Za razliku od Virgl i Venus konteksta, koji rade na razini API-a OpenGL i Vulkan, DRM kontekst implementiran je na razini UAPI jezgre Linuxa.\n<li class=\"l\"> Dodana je mogu\u0107nost kori\u0161tenja jezika C++ za razvoj dodataka za generator koda TCG (Tiny Code Generator).\n<li class=\"l\"> U bloknom drajveru NFS dodana je podr\u0161ka za kompilaciju s bibliotekom libnfs 6.\n<li class=\"l\"> U bloknom drajveru curl dodana je opcija \u00abforce-range\u00bb za prisilno kori\u0161tenje HTTP zaglavlja \u00abRange\u00bb pri preuzimanju slika bez prethodnog provjeravanja njegove podr\u0161ke posebnim zahtjevom s zaglavljem HEAD.\n<li class=\"l\"> U bloknom drajveru FUSE onemogu\u0107ena je obrada operacija eksportiranja u sinkronom na\u010dinu, \u0161to je dovelo do blokiranja pokretanja virtualne ma\u0161ine do zavr\u0161etka obrade drugih FUSE-zahtjeva. Dodana je mogu\u0107nost kori\u0161tenja vi\u0161e I\/O niti (iothread) prilikom izvo\u0111enja eksportiranja u FUSE.\n<li class=\"l\"> U emulatoru arhitekture x86 dodana je podr\u0161ka za CPU Intel Diamond Rapids (\u00abXeon 7\u00bb).\n<li class=\"l\"> U emulatoru arhitekture ARM dodana su procesorska pro\u0161irenja FEAT_ASID2 i FEAT_E2H0. U generatoru koda TCG implementirana je emulacija pro\u0161irenja SME (Scalable Matrix Extension).\n<li class=\"l\"> U emulatoru arhitekture HPPA dodana je podr\u0161ka za emulaciju 64-bitnih CPU-a s 40- i 44-bitnim adresnim prostorom. Pomo\u0107u SeaBIOS-hppa 24 osigurana je inicijalizacija PCI-kontrolera Astro, koja omogu\u0107uje kori\u0161tenje PCI-grafi\u010dkih kartica na 64-bitnim sustavima.\n<li class=\"l\"> U emulatoru arhitekture LoongArch pojavila se mogu\u0107nost migracije PMU (Performance Monitoring Unit) prilikom kori\u0161tenja hipervizora KVM. U generatoru koda TCG implementirana je emulacija pro\u0161irenja LA v1.1, sc.q i llacq\/screl, kao i instrukcija FRECIP i DRECIP za izra\u010dunavanje obratnih vrijednosti.\n<li class=\"l\"> U
