Run Kata Containers on a Service VM
|
|
###################################
|
|
|
|
This tutorial describes how to install, configure, and run `Kata Containers
|
|
<https://katacontainers.io/>`_ on the ACRN Service VM. In this configuration,
|
|
Kata Containers leverage the ACRN hypervisor instead of QEMU which is used by
|
|
default. Refer to the `Kata Containers with ACRN
|
|
<https://drive.google.com/file/d/1ZrqM5ouWUJA0FeIWhU_aitEJe8781rpe/view?usp=sharing>`_
|
|
presentation from a previous ACRN Project Technical Community Meeting for more
|
|
details on Kata Containers and how the integration with ACRN has been done.

|
|
|
|
#. Refer to the :ref:`ACRN supported hardware <hardware>`.
|
|
#. For a default prebuilt ACRN binary in the E2E package, you must have 4 CPU cores or enable "CPU Hyper-Threading” in order to have 4 CPU threads for 2 CPU cores.
|
|
#. Follow :ref:`these instructions <quick-setup-guide>` to set up the ACRN Service VM.
|
|
#. Build the ACRN kernel (required to support ``macvtap``, enabled by default since `247a3ba9243b <https://github.com/projectacrn/acrn-kernel/commit/247a3ba9243b1fd8c2d763158d55f8791a9cac94>`_).

|
|
$ git clone https://github.com/projectacrn/acrn-kernel.git
|
|
$ cd acrn-kernel
|
|
$ cp kernel_config_sos .config
|
|
$ make clean && make olddefconfig && make && make modules_install INSTALL_MOD_PATH=out/
|
|
|
|
Log in to the Service VM and use the new ACRN kernel:
|
|
|
|
.. code-block:: none
|
|
|
|
$ sudo mount /dev/sda1 /mnt
|
|
$ sudo scp -r <user name>@<host address>:<your workspace>/acrn-kernel/arch/x86/boot/bzImage /mnt/
|
|
$ sudo scp -r <user name>@<host address>:<your workspace>/acrn-kernel/out/lib/modules/* /lib/modules/
|
|
$ conf_file=`sed -n '$ s/default //p' /mnt/loader/loader.conf`.conf
|
|
$ kernel_img=`sed -n 2p /mnt/loader/entries/$conf_file | cut -d'/' -f4`
|
|
$ sed -i "s/$kernel_img/bzImage/g" /mnt/loader/entries/$conf_file
|
|
$ sync && sudo umount /mnt && reboot
|
|
|
|
.. note::
|
|
Adjust the EFI System Partition (ESP) device node (``/dev/sda1`` in the example above) to match your system setup.
