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):

Then install the ACRN-patched kernel package::
sudo dpkg -i acrn_kernel_deb_package.deb
After that, you're ready to reboot.
.. rst-class:: numbered-step
Boot ACRN using the multiboot2 grub choice
******************************************
This time when you boot your target system you'll see some new options:
.. code-block:: console
:emphasize-lines: 4
Ubuntu
Advanced options for Ubuntu
System setup
*ACRN multiboot2
If your target system has a serial port active, you can simply hit
:kbd:`return` (or wait for the timeout) to boot with this
``ACRN multiboot2`` choice.
.. important:: If you don't have an active serial port, you'll need to
edit the grub configuration a bit by pressing :kbd:`e` (for edit) and
remove the ``i915.modeset=0 video=efifb:off`` parameters at the end of
the multiboot2 grub command:
.. code-block:: console
:emphasize-lines: 8
setparams 'ACRN multiboot2 '
load_video
insmod gzio
insmod part_gpt
insmod ext2
search --no-floppy --fs-uuid --set $uuid
multiboot2 /boot/acrn.industry.nuc7i7dnb.bin root=PARTUUID="06d5265d-863a-4bc0-b469-66b5e6b8a9cb" i915.modeset=0 video=efifb:off
module2 /boot/vmlinuz-5.4.43.PKT-200203T060100Z Linux_bzImage
Then press :kbd:`F10` to continue booting
.. rst-class:: numbered-step
Verify ACRN is running
**********************
After the system boots, you can verify ACRN was detected and is running
by looking at the dmesg log:
.. code-block:: console
:emphasize-lines: 3
