Como um emulador, o QEMU permite executar programas compilados para uma plataforma de hardware em sistemas 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 se aproxima do sistema de hardware 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 a suporte \u00e0 emula\u00e7\u00e3o completa para 14 arquiteturas de hardware, com o n\u00famero de dispositivos de hardware emulados ultrapassando 400. Na prepara\u00e7\u00e3o da vers\u00e3o 11.0, mais de 2700 mudan\u00e7as foram feitas por 226 desenvolvedores.     <\/p>\n<p>Principais melhorias adicionadas ao QEMU 10.1:   <\/p>\n<ul>\n<li class=\"l\"> No VFIO (Virtual Function I\/O) foi implementado o suporte inicial ao mapeamento de mem\u00f3ria para ambientes virtuais confidenciais, onde a criptografia de mem\u00f3ria \u00e9 usada para proteger contra interfer\u00eancias e an\u00e1lises por parte do administrador do sistema host. Esta mudan\u00e7a permite a organiza\u00e7\u00e3o de passagem de dispositivos em sistemas convidados protegidos por mecanismos Intel TDX (Trusted Domain Extensions) e AMD SEV-SNP (Secure Nested Paging).\n<li class=\"l\"> Foi adicionada a possibilidade de usar o mecanismo multifd para acelerar a Live-migra\u00e7\u00e3o no modo postcopy, onde inicialmente \u00e9 transferido e iniciado no host de destino, <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/vps\/abuzoustojchivye-vps\/\"   title=\"m\u00e1quina virtual\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"4208\">m\u00e1quina virtual<\/a>, e depois o conte\u00fado n\u00e3o utilizado da mem\u00f3ria RAM \u00e9 transferido gradualmente. O modo de Live-migra\u00e7\u00e3o precopy foi otimizado. O suporte \u00e0 migra\u00e7\u00e3o RDMA para IPv6 foi adicionado.\n<li class=\"l\"> No QEMU Guest Agent, foi adicionada o comando &#171;guest-get-load&#187; para obter informa\u00e7\u00f5es sobre o n\u00edvel de carga do sistema (load average) em m\u00e1quinas virtuais com Windows.\n<li class=\"l\"> No virtio-gpu foi adicionada a suporte \u00e0 substitui\u00e7\u00e3o de nome no EDID (Extended Display Identification Data).\n<li class=\"l\"> No emulador da arquitetura x86, foi implementada a possibilidade de usar o mecanismo Intel TDX (Trusted Domain Extensions) para criptografia da mem\u00f3ria RAM de sistemas convidados operando sob o hipervisor KVM. Tamb\u00e9m foi adicionado suporte \u00e0 inicializa\u00e7\u00e3o de sistemas confidenciais <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/vps\/\"   title=\"m\u00e1quinas virtuais\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2221\">m\u00e1quinas virtuais<\/a>  no formato IGVM (Independent Guest Virtual Machine), cujos mecanismos de prote\u00e7\u00e3o utilizam Intel TDX e AMD SEV-SNP.\n<li class=\"l\"> No emulador da arquitetura ARM, foi implementado o suporte a placas (Analog Devices &#8216;max78000fthr&#8217;, &#8216;ast2700fc&#8217;, Meta &#8216;catalina-bmc&#8217;, NVIDIA &#8216;gb200-bmc&#8217; e &#8216;ast2700a0-evb&#8217;. Foi adicionada a emula\u00e7\u00e3o das extens\u00f5es de CPU FEAT_SME2, FEAT_SME2p1, FEAT_SME_B16B16, FEAT_SME_F16F16, FEAT_SVE_B16B16 e FEAT_SVE2p1. Ao padr\u00e3o da plataforma ARM &#8216;virt&#8217;, foi adicionado suporte \u00e0 virtualiza\u00e7\u00e3o aninhada ao usar KVM, assim como suporte ao barramento CXL (Compute Express Link) e conex\u00e3o a quente de dispositivos PCI com ACPI.\n<li class=\"l\">  No emulador da arquitetura RISC-V, foi implementada a emula\u00e7\u00e3o do processador Kunminghu e da plataforma baseada nele. Foi adicionado suporte \u00e0 extens\u00e3o da arquitetura do conjunto de instru\u00e7\u00f5es Ziccif com a implementa\u00e7\u00e3o de uma variante at\u00f4mica da instru\u00e7\u00e3o fetch.\n<li class=\"l\"> No emulador da arquitetura LoongArch, foi adicionado suporte \u00e0 emula\u00e7\u00e3o do controlador de interrup\u00e7\u00f5es irqchip no lado do n\u00facleo.\n<li class=\"l\"> Foi adicionado suporte experimental \u00e0 compila\u00e7\u00e3o para a representa\u00e7\u00e3o WebAssembly (WASM), utilizando o compilador Emscripten.\n<li class=\"l\"> Nos componentes para ambientes host, o suporte ao Debian 11 foi descontinuado.    <\/ul>\n<p>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=63782\">opennet.ru<\/a>
