When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC). By using dynamic translation, it achieves very good performance. When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU. QEMU supports virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux. When using KVM, QEMU can virtualize x86, server and embedded PowerPC, and S390 guests. http://qemu.org/ if BR2_PACKAGE_QEMU comment "Emulators selection" config BR2_PACKAGE_QEMU_CUSTOM_TARGETS string "Enable specific targets" help Enter here the list of QEMU targets you want to build.
