![]() ![]() ![]() The following subsections show the minimum QEMU command lines needed to run HelenOS on the respective QEMU machine. the guest and host CPUs are compatible (ia32 vs.there is no running instance of VirtualBox or Xen hardware virtualization is not already in use, i.e.the host CPU supports hardware virtualization and this support is enabled in it.KVM is supported by the host operating system, e.g.In general, KVM can only be used, if the following criteria are met: If circumstances are right, it is possible to choose the second mode and benefit from better performance by appending the -enable-kvm option to the QEMU command lines below. QEMU supports two modes of operation: binary translation and hardware virtualization. You should be able to install a prepackaged version of QEMU from your distribution or you can build QEMU from scratch using a simple script which comes with HelenOS sources: We are assuming a sufficiently recent version of QEMU, such as 2.5.0 and newer. Please note that this does not work for the prebuilt images. For some architectures, it also determines networking, sound, USB and disk options. whether you built for ia32 or mips) and starts the appropriate emulator. It detects emulator options to use from the used HelenOS configuration (e.g. The script is started using the following command: But if you build the image by yourself, you may use our emulator wrapper script instead. Here you will learn how to start the emulator manually, which is necessary if you download the image. This page describes how to use QEMU to run various HelenOS images you either downloaded or built yourself.
