QEMU guest may be presented with QEMU's user mode network stack (SLIRP) or directly bridged host's network interface.įor more information about QEMU networking options, see QEMU Networking Documentation Using user mode network stack To add a virtual network card, add one of the following command-line options: To use networking, a network interface card must be presented to the guest system. Note that the system will boot into a GUI, but it will not be possible to control it using mouse or keyboard.įor general information about networking in HelenOS, please see UsersGuide/Networking. Qemu-system-sparc64 -cdrom image.iso -boot d For an image.iso built for the sparc64/ultra profile, do: QEMU can emulate a custom sun4u machine and HelenOS partially supports it. Qemu-system-ppc -cdrom image.iso -boot d -m 256 For an image.iso built for the ppc32 profile, do: Image.boot is the image built for the mips32/malte-be or mips32/malta-le profiles, respectively. Qemu-system-mipsel -cpu 4Kc -kernel image.boot -append "console=devices/\\hw\\pci0\\00:0a.0\\com1\\a" -nographic Qemu-system-mips -cpu 4Kc -kernel image.boot -append "console=devices/\\hw\\pci0\\00:0a.0\\com1\\a" -nographic QEMU can emulate MIPS Malta and HelenOS has limited support for it. For an image.iso built for the ia32 profile, just run: Qemu-system-arm -M integratorcp -kernel image.boot For an image.boot built for the arm32/integratorcp profile, do: For an image.iso built for the amd64 or ia32 profile, simply run: QEMU can emulate a generic PC equipped with a 64-bit processor. The later sections will show you how to configure additional hardware. When spawned like this, the simulated QEMU machine may be missing some hardware which limits what hardware HelenOS can detect on it and in turn what you can do with it. 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. Working with USB devices in the control console.Bridging virtual network device with host's network interface.
