Come emulatore, QEMU consente di eseguire programmi compilati per una piattaforma hardware su un sistema con un'architettura completamente diversa, ad esempio, eseguire un'applicazione per ARM su un PC compatibile con x86. In modalit\u00e0 virtualizzazione, QEMU offre prestazioni di esecuzione del codice in un ambiente isolato simili a quelle di un sistema hardware grazie all'esecuzione diretta delle istruzioni sulla CPU e all'utilizzo dell'iperpvisor Xen o del modulo KVM in Linux, o del modulo NVMM in NetBSD.    <\/p>\n<p>Il progetto \u00e8 stato originariamente creato da Fabrice Bellard con l'obiettivo di consentire l'esecuzione di file eseguibili Linux compilati per la piattaforma x86 su architetture diverse da x86. Nel corso degli anni, \u00e8 stato aggiunto il supporto per l'emulazione completa di 14 architetture hardware, con oltre 400 dispositivi hardware emulati. Per la versione 10.2.0 sono state apportate oltre 2200 modifiche da 188 sviluppatori.     <\/p>\n<p>Miglioramenti chiave aggiunti in QEMU 10.2:   <\/p>\n<ul>\n<li class=\"l\"> Nel backend 9pfs, che consente di utilizzare il file system di rete Plan 9 per l'accesso di una macchina virtuale a un'altra, \u00e8 stato aggiunto il supporto per FreeBSD.\n<li class=\"l\"> \u00c8 stata aggiunta una nuova modalit\u00e0 di Live-migrazione 'cpr-exec', che consente di ridurre il consumo di risorse durante l'aggiornamento. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/vps\/\"   title=\"macchine virtuali\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2251\">macchine virtuali<\/a> e potenzialmente riutilizzare gli stati e le connessioni esistenti durante l'aggiornamento.\n<li class=\"l\"> Il ciclo principale di elaborazione eventi in QEMU \u00e8 stato convertito per utilizzare l'interfaccia di input\/output asincrona io_uring sui sistemi che la supportano, il che porta a un aumento delle prestazioni.\n<li class=\"l\"> Migliorata l'emulazione in modalit\u00e0 user-mode, che consente di eseguire processi separati compilati per una CPU diversa. \u00c8 stata implementata la syscall fchmodat2, aggiunto il supporto per i flag MADV_DONTDUMP e MADV_DODUMP, migliorato il supporto per le architetture aarch64, hppa e microblaze.\n<li class=\"l\"> L'emulatore dell'architettura ARM ora supporta il modello di scheda amd-versal2-virt con implementazione del SoC virtuale AMD Versal. \u00c8 stato migliorato il supporto per le schede 'AST2600', 'AST2700', 'AST1030' e 'xlnx-zynqmp'. \u00c8 stata implementata l'emulazione delle estensioni CPU FEAT_SCTLR2, FEAT_TCR2, FEAT_CSSC, FEAT_LSE128, FEAT_ATS1A, FEAT_RME_GPC2, FEAT_AIE, FEAT_MEC e FEAT_GCS.\n<li class=\"l\"> Nell'emulatore dell'architettura HPPA \u00e8 stata aggiunta la possibilit\u00e0 di emulare la workstation HP 715\/64, il controller SCSI NCR 53c710 e il controller di input\/output HP LASI.\n<li class=\"l\"> Nell'emulatore dell'architettura PowerPC \u00e8 stata aggiunta la supporto per le CPU PowerNV11 e PPE42. Per l'hardware pSeries \u00e8 stato implementato un meccanismo FADUMP (Firmware-Assisted Dump) per la creazione di dump dello stato dopo un crash del sistema.\n<li class=\"l\"> Nell'emulatore dell'architettura RISC-V \u00e8 stato implementato l'API MonitorDef HMP, e fino alla versione 1.7 \u00e8 stata aggiornata l'OpenSBI (Open Supervisor Binary Interface), apportando un ampio numero di correzioni.\n<li class=\"l\"> Nell'emulatore dell'architettura s390x, per migliorare le prestazioni, la tecnologia di sostituzione delle interruzioni virtuali tramite irqfd \u00e8 stata impiegata per virtio-pci.        <\/ul>\n<p>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=64500\">opennet.ru<\/a>
