![]() We recommend going through the pages in order to learn how to use UTM. The pages are organized in order of most important information to the least important. Check out the links on the left for more information. In short, it allows you to run Windows, Linux, and more on your Mac, iPhone, and iPad. The Linux kernel is of course cross-compilation friendly you can cross-compile the Linux kernel by setting the architecture and cross-tools prefix when invoking make, for instance if your cross-tools are named arm-linux-gnueabi-gcc, arm-linux-gnueabi-ld etc.UTM is a full featured system emulator and virtual machine host for iOS and macOS. Some build systems will autodetect cross-compilation when passed host and target architectures, but others might expect the cross-compiler to be set in the CC, LD etc. Specific software such as the kernel or bootloaders are easily cross-compiled this works as expected under Ubuntu, it's a matter of making sure the relevant cross-compiler is in the $PATH, either by installing it from packages which ship it in /usr/bin, or by installing it to /usr/local/bin, or by installing it in one's $HOME/bin directory and appending ~/bin to the $PATH. The Ubuntu 10.04 versatile kernels should work fine for this mode and are available at but you don't need the initrd part of them. Youshchenko provides some ARM-specific instructions at with custom kernels. The Debian wiki provides instructions for various architectures at and Nikita V. Qemubuilder is a pbuilder mode using QEMU as its backend it launches QEMU in machine emulation mode and builds the package in the virtual machine. (lucid-powerpc-source) % exit qemubuilder (lucid-powerpc-source) % apt-get dist- upgrade $ sudo schroot -c lucid-powerpc-source - u root To install Ubuntu on ARM using the alternate installer, create a qemu harddisk with: Using "rootstock" see ARM/RootfsFromScratchīy hand, using debootstrap see ARM/RootfsFromScratch/QemuDebootstrap using the "versatile" netboot images of the alternate installer see below.There are various ways to create a QEMU virtual machine.įor ARM, the currently supported methods are: It should not be considered a secure sandbox though.įull system emulation should be preferred to run programs like gdb, or to test a real installed system perhaps with graphical apps, or running an OpenSSH server. ![]() However, it provides a much better emulation for guest programs and isolates from the host. It is much slower than user mode emulation since the target kernel is emulated, as well as device input/output, interrupts etc. This QEMU mode emulates a virtual machine with a configurable CPU, video card, memory size and mode. In summary, user mode emulation is a nice mode when it works and should be preferred when speed matters, but full system emulation mode should be used for a more complete emulation. One may combine syscall emulation with some tools like pbuilder or sbuild read on for specific instructions for each tool. This chroot should behave mostly like a regular chroot, with the associated drawbacks (no isolation as in virtual machines) and the limitations of qemu syscall emulation. Such a chroot can be created with the qemu-debootstrap command (from the qemu-kvm-extras-static package) which behaves like debootstrap, but copies a static qemu interpreter in the chroot as well. % sudo cp /usr/bin/qemu-arm-static usr/bin/qemu-arm- staticīin dev home lost+ found mnt proc sbin srv tmp varīoot etc lib media opt root selinux sys usr ![]()
