QEMU

Introduction

Quick Emulator (QEMU) can simulate the scenario where a kernel runs on different boards, so that the kernel no longer depends on physical development boards.

Constraints

QEMU applies only to the OpenHarmony kernel.

QEMU Install

  1. Install dependencies(Ubuntu 18+)

    sudo apt install build-essential zlib1g-dev pkg-config libglib2.0-dev  binutils-dev libboost-all-dev autoconf libtool libssl-dev libpixman-1-dev virtualenv flex bison
  2. Acquiring Source Code

    wget https://download.qemu.org/qemu-6.2.0.tar.xz

    or

    Download from official website: qemu-6.2.0.tar.xz

  3. Compile and install

    tar -xf qemu-6.2.0.tar.xz
    cd qemu-6.2.0
    mkdir build && cd build
    ../configure --prefix=qemu_installation_path
    make -j16

    Wait for the compilation to finish and execute the installation command:

    make install

    Finally, add the installation path to the environment variable:

    vim ~/.bashrc

    Add the following command line to the last line of ~/.bashrc:

    export PATH=$PATH:qemu_installation_path
