Kao emulatore, QEMU omogu\u0107uje pokretanje programa sastavljenog za jednu hardversku platformu na sustavu s potpuno druga\u010dijom arhitekturom, na primjer, izvr\u0161avanje aplikacije za ARM na x86-kompatibilnom PC-u. U na\u010dinu virtualizacije, ostvarena izvedba koda u izoliranom okru\u017eenju bliska je hardverskom sustavu zahvaljuju\u0107i izravnom izvr\u0161avanju instrukcija na CPU-u i kori\u0161tenju hipervizora Xen ili modula KVM u Linuxu, ili modula NVMM u NetBSD-u.    <\/p>\n<p>Projekat je prvotno stvorio Fabrice Bellard s ciljem omogu\u0107avanja pokretanja izvr\u0161nih datoteka Linuxa sastavljenih za x86 platformu na arhitekturama razli\u010ditim od x86. Tijekom godina razvoja podr\u0161ka je dodana za potpunu emulaciju 14 hardverskih arhitektura, a broj emuliranih hardverskih ure\u0111aja prema\u0161io je 400. Prilikom pripreme verzije 10.0 izvr\u0161eno je vi\u0161e od 2800 promjena od 211 developera.     <\/p>\n<p>Klju\u010dna pobolj\u0161anja dodana u QEMU 10.0:   <\/p>\n<ul>\n<li class=\"l\"> U virtio-scsi drajver, koji pru\u017ea virtualni SCSI kontroler (SCSI Host Bus Adapter) za <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/hr\/vps\/\"   title=\"virtualnih ma\u0161ina\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2201\">virtualnih ma\u0161ina<\/a>, dodana je podr\u0161ka za vi\u0161erazinsku sistemu redova (multiqueue), koja omogu\u0107uje dijeljenje redova za razli\u010dite blok ure\u0111aje za osiguranje vi\u0161edretvenog pristupa na vi\u0161ekrambilnim sustavima (razli\u010diti redovi jednog ure\u0111aja mogu se obra\u0111ivati razli\u010ditim I\/O nitima). U usporedbi s drajverom virtualnog blok ure\u0111aja (virtio-blk), virtualni SCSI kontroler malo zaostaje u performansama, ali omogu\u0107uje kori\u0161tenje vi\u0161e od 28 diskova.\n<li class=\"l\"> U VFIO (Virtual Function I\/O) pobolj\u0161ana je podr\u0161ka za propu\u0161tanje IGD (Integrated Graphics Device) za integrirane GPU-ove kori\u0161tene u 11 (Rocket Lake) i 12 (Alder Lake) generacijama Intel procesora. Dodana je podr\u0161ka za starije GPU-ove ATI (x550). Implementirana je osnovna podr\u0161ka za PCI PM (Power Management).\n<li class=\"l\"> Dokumentacija za QMP protokol (QEMU Machine Protocol) zna\u010dajno je revidirana i pro\u0161irena, omogu\u0107uju\u0107i aplikacijama upravljanje QEMU-om.\n<li class=\"l\"> Dodana je nova opcija Live-migracije &#171;cpr-transfer&#187; (CheckPoint and Restart), koja omogu\u0107ava premje\u0161tanje gostuju\u0107eg sustava u novu instancu QEMU koja se pokre\u0107e na istom hostu. Ova opcija minimizira vrijeme pauziranja tako \u0161to reflektira memoriju gostuju\u0107eg sustava u virtualni adresni prostor novog QEMU bez kopiranja sadr\u017eaja.\n<li class=\"l\"> Dodani su grafi\u010dki ure\u0111aji &#8216;apple-gfx-pci&#8217; i &#8216;apple-gfx-mmio&#8217;, koji koriste okvir ParavirtualizedGraphics, dostupan u macOS za hardversko ubrzanje grafike u gostuju\u0107im sustavima. Prvi upravlja\u010dki program namijenjen je za kori\u0161tenje na ure\u0111ajima x86-64, dok je drugi &#8212; ARM64.\n<li class=\"l\"> U emulatoru x86 arhitekture implementirana je podr\u0161ka za modele procesora Intel Xeon Clearwater Forest i Sierra Forest v2.

Dodana je podr\u0161ka za pro\u0161irenja arhitekture skupa instrukcija &#8216;svukte&#8217;, &#8216;ssstateen&#8217;, &#8216;smrnmi&#8217;, &#8216;smdbltrp&#8217;\/&#8217;ssdbltrp&#8217;, &#8216;supm&#8217;, &#8216;sspm&#8217;, kao i oznaka za prevo\u0111enje IOMMU i ure\u0111aje riscv-iommu-sys.\n<li class=\"l\"> U emulatoru HPPA arhitekture osigurana je emulacija Diva GSP BMC plo\u010da. Do verzije 18 a\u017eurirana je verzija firmvera SeaBIOS-hppa. Pove\u0107ana je brzina prevo\u0111enja. Pobolj\u0161an je kod za resetiranje virtualnog CPU-a. Na 64-bitnim sustavima osigurana je emulacija konfiguracija s memorijom do 256 GB.\n<li class=\"l\"> U emulatoru LoongArch arhitekture dodana je podr\u0161ka za vru\u0107e povezivanje CPU-a. Implementiran je paravirtualizirani IPI (inter-processor interrupt). Osigurano je pra\u0107enje vremena \u010dekanja na resurse od hipervizora. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/hr\/vps\/abuzoustojchivye-vps\/\"   title=\"KVM\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"4440\">KVM<\/a>. Dodana je podr\u0161ka za virtualno usmjeravanje vanjskih prekida (extioi).\n<li class=\"l\"> U emulatoru s390x arhitekture dodana je podr\u0161ka za 17. generaciju CPU mainframea i implementirana je podr\u0161ka za virtio-mem. Kako bi se pobolj\u0161ala u\u010dinkovitost, dodana je mogu\u0107nost interakcije s PCI ure\u0111ajima zaobilaze\u0107i IOMMU.    <\/ul>\n<p>Izvor: <a content=\"nofollow\" rel=\"nofollow\"
