Como emulador, o QEMU permite executar um programa constru\u00eddo para uma plataforma de hardware em um sistema com uma arquitetura completamente diferente, por exemplo, executar um aplicativo para ARM em um PC compat\u00edvel com x86. No modo de virtualiza\u00e7\u00e3o, o desempenho da execu\u00e7\u00e3o de c\u00f3digo em um ambiente isolado est\u00e1 pr\u00f3ximo do sistema f\u00edsico, devido \u00e0 execu\u00e7\u00e3o direta de instru\u00e7\u00f5es na CPU e ao uso do hipervisor Xen ou do m\u00f3dulo KVM no Linux, ou do m\u00f3dulo NVMM no NetBSD.    <\/p>\n<p>O projeto foi inicialmente criado por Fabrice Bellard com o objetivo de permitir a execu\u00e7\u00e3o de arquivos execut\u00e1veis do Linux compilados para a plataforma x86 em arquiteturas diferentes de x86. Ao longo dos anos de desenvolvimento, foi adicionada o suporte para emula\u00e7\u00e3o completa de 14 arquiteturas de hardware, e o n\u00famero de dispositivos de hardware emulados ultrapassou 400. Na prepara\u00e7\u00e3o da vers\u00e3o 11.0.0, foram feitas mais de 2500 altera\u00e7\u00f5es por 237 desenvolvedores.     <\/p>\n<p>Principais melhorias adicionadas no QEMU 11.0:   <\/p>\n<ul>\n<li class=\"l\"> Removido o suporte para sistemas host de 32 bits, que foi declarado obsoleto em abril do ano passado na vers\u00e3o 10.0 do QEMU. Na vers\u00e3o de dezembro 10.2, o suporte para as plataformas mips32 e ppc32 foi interrompido no gerador de c\u00f3digo TCG (Tiny Code Generator), e na vers\u00e3o 11.0 do QEMU, as restantes plataformas i386, arm, ppc e riscv32 foram removidas, al\u00e9m de uma limpeza da base de c\u00f3digo e do sistema de constru\u00e7\u00e3o, eliminando componentes para opera\u00e7\u00e3o em hosts de 32 bits.\n<li class=\"l\"> Foi implementado o acelerador de virtualiza\u00e7\u00e3o \"nitro\" (\"-accel nitor\") e um novo tipo de sistemas emulados \"nitro\", permitindo o lan\u00e7amento de enclaves isolados baseados na tecnologia de computa\u00e7\u00e3o confidencial AWS Nitro Enclave no QEMU, por exemplo, para testes locais em ambientes Nitro Enclave. Na AWS EC2, a tecnologia Nitro Enclave permite o lan\u00e7amento de enclaves isolados aninhados em uma m\u00e1quina virtual para trabalhar com dados confidenciais, alocando parte de seus recursos.\n<li class=\"l\"> Melhorado o suporte para aceleradores de virtualiza\u00e7\u00e3o MSHV (Microsoft Hypervisor) e WHPX (Microsoft Windows Hypervisor Platform Extensions).\n<li class=\"l\"> No uso do hipervisor KVM (\"-accel kvm\"), foi adicionada a suporte \u00e0 virtualiza\u00e7\u00e3o da extens\u00e3o Intel CET (Control-flow Enforcement Technology) para aplica\u00e7\u00e3o em <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/vps\/abuzoustojchivye-vps\/\"   title=\"m\u00e1quinas virtuais\" data-wpil-keyword-link=\"linked\">m\u00e1quinas virtuais<\/a> prote\u00e7\u00e3o contra exploits que utilizam m\u00e9todos de programa\u00e7\u00e3o orientada a retorno (ROP \u2014 Return-Oriented Programming). Tamb\u00e9m foi adicionada a suporte ao rein\u00edcio de confidenciais <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/vps\/\"   title=\"m\u00e1quinas virtuais\" data-wpil-keyword-link=\"linked\">m\u00e1quinas virtuais<\/a>, utilizando a criptografia de mem\u00f3ria com as extens\u00f5es AMD SEV-SNP (Secure Encrypted Virtualization \u2014 Secure Nested Paging) e Intel TDX (Trust Domain Extensions).\n<li class=\"l\"> O dispositivo VirtIO-GPU, que fornece o funcionamento da GPU virtual, agora permite a defini\u00e7\u00e3o de diferentes resolu\u00e7\u00f5es de tela para diferentes dispositivos de sa\u00edda.\n<li class=\"l\"> No VirtIO-GPU, foi adicionada a suporte a contextos DRM (Direct Rendering Manager native context), permitindo melhorar o desempenho ao trabalhar com o GPU virtual da m\u00e1quina convidada atrav\u00e9s da transmiss\u00e3o direta de comandos para o GPU host real. A suporte a contextos DRM \u00e9 ativada ao usar o novo dispositivo virtio-gpu-gl com a op\u00e7\u00e3o \"drm_native_context=on\". Ao contr\u00e1rio dos contextos Virgl e Venus, que operam no n\u00edvel da API OpenGL e Vulkan, o contexto DRM \u00e9 implementado no n\u00edvel UAPI do n\u00facleo Linux.\n<li class=\"l\"> Adicionada a possibilidade de usar a linguagem C++ para desenvolver plugins para o gerador de c\u00f3digo TCG (Tiny Code Generator).\n<li class=\"l\"> No driver de bloco NFS, adicionada a compatibilidade para compilar com a biblioteca libnfs 6.\n<li class=\"l\"> No driver de bloco curl, foi adicionada a op\u00e7\u00e3o \"force-range\" para for\u00e7ar o uso do cabe\u00e7alho HTTP \"Range\" ao baixar imagens, sem verifica\u00e7\u00e3o pr\u00e9via de suporte em uma solicita\u00e7\u00e3o separada com o cabe\u00e7alho HEAD.\n<li class=\"l\"> No driver de bloco FUSE, desativada a manipula\u00e7\u00e3o de opera\u00e7\u00f5es de exporta\u00e7\u00e3o em modo s\u00edncrono, que causava bloqueio no in\u00edcio da m\u00e1quina virtual at\u00e9 a conclus\u00e3o do processamento de outras solicita\u00e7\u00f5es FUSE. Adicionada a possibilidade de usar v\u00e1rias threads de entrada\/sa\u00edda (iothread) ao realizar exporta\u00e7\u00e3o em FUSE.\n<li class=\"l\"> No emulador da arquitetura x86, foi adicionada a suporte para CPU Intel Diamond Rapids (\"Xeon 7\").\n<li class=\"l\"> No emulador da arquitetura ARM, adicionadas as extens\u00f5es de CPU FEAT_ASID2 e FEAT_E2H0. No gerador de c\u00f3digo TCG, implementada a emula\u00e7\u00e3o das extens\u00f5es SME (Extens\u00e3o de Matriz Escal\u00e1vel).\n<li class=\"l\"> No emulador da arquitetura HPPA, adicionada a emula\u00e7\u00e3o de CPUs de 64 bits com espa\u00e7os de endere\u00e7o de 40 e 44 bits. A inicializa\u00e7\u00e3o do controlador PCI Astro, permitida pelo SeaBIOS-hppa 24, possibilita o uso de placas de v\u00eddeo PCI em sistemas de 64 bits.\n<li class=\"l\"> No emulador da arquitetura LoongArch, agora \u00e9 poss\u00edvel migrar PMU (Unidade de Monitoramento de Desempenho) ao usar o hipervisor KVM. No gerador de c\u00f3digo TCG, implementada a emula\u00e7\u00e3o das extens\u00f5es LA v1.1, sc.q e llacq\/screl, bem como das instru\u00e7\u00f5es FRECIP e DRECIP para c\u00e1lculo de valores inversos.\n<li class=\"l\"> No emulador da arquitetura PowerPC, adicionada a compatibilidade com snapshots.\n<li class=\"l\"> O emulador da arquitetura RISC-V implementou suporte para a CPU MIPS P8700 e extens\u00f5es do conjunto de instru\u00e7\u00f5es Zilsd, Zclsd, ZALASR e Smpmpmt.\n<li class=\"l\">  No emulador da arquitetura s390, foi adicionada suporte para inicializa\u00e7\u00e3o a partir de dispositivos virtio-blk-pci e implementada a emula\u00e7\u00e3o da instru\u00e7\u00e3o \"DIVIDE TO INTEGER\".\n<li class=\"l\"> Uma corre\u00e7\u00e3o foi aceita, reduzindo de 50 a 80 vezes a
