.. _debian_packaging: ACRN Installation via Debian Packages ##################################### Debian packages provide a simple way to build and package a collection of ACRN configurations on a development system, based on a set of hardware platforms and scenario choices. You can then copy the packages onto your target platform, select a particular configuration and reboot the system with ACRN and an Ubuntu Service VM up and running. Follow these instructions to build Debian packages for the acrn-hypervisor and acrn-kernel, install them on your target system, and boot running ACRN. .. rst-class:: numbered-step Set Up Prerequisites ******************** Your development system should be running Ubuntu 18.04 and be connected to the internet. (You'll be installing software with ``apt`` and from Pypi and downloading ACRN software from GitHub.) It's likely you've already got python3 on your system, but we can make sure by installing it with:: sudo apt install python3 All of the Debian packaging work is handled by a script found in the ACRN GitHub repo. If you don't have it downloaded already, clone the ACRN repo with:: git clone https://github.com/projectacrn/acrn-hypervisor.git All the configuration files and scripts to build the Debian packages are in the ``misc/packaging`` folder, so let's go there:: cd acrn-hypervisor/misc/packaging .. rst-class:: numbered-step Configure Debian Packaging Details ********************************** The build and packaging script ``install_uSoS.py`` does all the work to build and make the Debian packages. You configure what the script does by editing its configuration file, ``release.json``. Comments in the JSON file document how you can adjust things to your specific needs. For example, the default ``release.json`` file builds for all three default ACRN configurations (industry, hybrid, and logical_partition) and for two supported boards (nuc717dnb and whl-ipc-i5). .. important:: In the current implementation of this packaging script, if you change the ``release.json`` boards configuration choices, you'll also need to manually update the ``acrn-hypervisor.postinst`` script to match. Here's the default ``release.json`` configuration: .. literalinclude:: release.json .. rst-class:: numbered-step Run the Package-Building Script ******************************* The ``install_uSoS.py`` Python script does all the work to install needed tools (such as make, gnu-efi, libssl-dev, libpciaccess-dev, uuid-dev, and more). It also verifies that tool versions (such as the gcc compiler) are appropriate (as configured in the ``release.json`` file). The script runs without further user input, and must be run with ``sudo``:: sudo python3 install_uSoS.py With the default ``release.json`` configuration, this script will run for about 30 minutes, but could take longer depending on your internet speed (for downloading files) and overall computer performance (for compiling the Linux kernel, ACRN hypervisor, and ACRN tools). When done, it creates two Debian packages: * ``acrn_deb_package.deb`` with the ACRN hypervisor and tools built for each configuration combination, and * ``acrn_kernel_deb_package.deb`` with the ACRN-patched Linux kernel. You'll need to copy these two files onto your target system, either via the network or simply by using a USB drive. .. rst-class:: numbered-step Prepare Your Target System With Ubuntu 18.04 ******************************************** Your target system must be one of the choices listed in the ``release.json`` file and should be running Ubuntu 18.04. Make sure it's updated using the commands:: sudo apt update sudo apt upgrade Reboot your system to complete the installation. .. rst-class:: numbered-step Install Debian Packages on Your Target System ********************************************* Copy the Debian packages you created on your development system, for example, using a USB drive. Then install the ACRN Debian package:: sudo dpkg -i acrn_deb_package.deb Make your choices for scenario, board, and which disk to use, for example, this selects the industry scenario, nuc7i7dnb board, and installation on the NVMe drive (input is highlighted): .. code-block:: console :emphasize-lines: 11, 16, 23 Selecting previously unselected package acrn-package.
