< p > QEMU est un émulateur de machine générique à source ouverte. Il effectue une virtualisation complète du système, où vous exécutez un noyau séparé sur la VM et ce noyau voit une plate-forme complète avec votre nombre spécialisé de processeurs, la quantité de RAM, les disques et les interfaces Ethernet, USB et audio. La QEMU peut émuler une architecture différente. Vous pouvez exécuter une commande QEMU sur votre plate-forme Linux/x86_64 et la faire émuler : un système ARM sur lequel vous exécutez Android, ou un UltraSPARC sur lequel vous exécutez Solaris, ou simplement une plate-forme x86_64 sur laquelle vous exécutez Windows.< / p >
