En tant qu'\u00e9mulateur, QEMU permet d'ex\u00e9cuter un programme compil\u00e9 pour une plateforme mat\u00e9rielle sur un syst\u00e8me ayant une architecture compl\u00e8tement diff\u00e9rente, par exemple, ex\u00e9cuter une application pour ARM sur un PC compatible x86. En mode virtualisation, la performance d'ex\u00e9cution du code dans un environnement isol\u00e9 est proche de celle d'un syst\u00e8me mat\u00e9riel, gr\u00e2ce \u00e0 l'ex\u00e9cution directe des instructions sur le CPU et \u00e0 l'utilisation de l'hyperviseur Xen ou du module KVM sous Linux, ou du module NVMM sous NetBSD.    <\/p>\n<p>Le projet a \u00e9t\u00e9 initialement cr\u00e9\u00e9 par Fabrice Bellard dans le but de permettre l'ex\u00e9cution de fichiers ex\u00e9cutables Linux compil\u00e9s pour l'architecture x86 sur des architectures diff\u00e9rentes de x86. Au fil des ann\u00e9es de d\u00e9veloppement, la prise en charge de l'\u00e9mulation compl\u00e8te a \u00e9t\u00e9 ajout\u00e9e pour 14 architectures mat\u00e9rielles, et le nombre de dispositifs mat\u00e9riels \u00e9mul\u00e9s a d\u00e9pass\u00e9 400. Pour la pr\u00e9paration de la version 11.0, plus de 2700 modifications ont \u00e9t\u00e9 apport\u00e9es par 226 d\u00e9veloppeurs.     <\/p>\n<p>Am\u00e9liorations cl\u00e9s ajout\u00e9es dans QEMU 10.1 :   <\/p>\n<ul>\n<li class=\"l\"> Dans VFIO (Virtual Function I\/O), un support initial du mappage de la m\u00e9moire pour des environnements invit\u00e9s confidentiels a \u00e9t\u00e9 impl\u00e9ment\u00e9, dans lesquels le chiffrement de la m\u00e9moire est utilis\u00e9 pour se prot\u00e9ger contre l'intervention et l'analyse par l'administrateur du syst\u00e8me h\u00f4te. Ce changement permet d'organiser le passage de dispositifs vers des syst\u00e8mes invit\u00e9s prot\u00e9g\u00e9s par des m\u00e9canismes Intel TDX (Trusted Domain Extensions) et AMD SEV-SNP (Secure Nested Paging).\n<li class=\"l\"> Il est d\u00e9sormais possible d'utiliser le m\u00e9canisme multifd pour acc\u00e9l\u00e9rer la migration Live en mode postcopy, dans lequel, au d\u00e9part, la cible est transf\u00e9r\u00e9e et lanc\u00e9e sur l'h\u00f4te cible <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/fr\/vps\/abuzoustojchivye-vps\/\"   title=\"machine virtuelle\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"4208\">machine virtuelle<\/a>, puis le contenu non sollicit\u00e9 de la m\u00e9moire vive est transf\u00e9r\u00e9 progressivement.
