Pre-requisites
**************
.. _kata prerequisites:
https://github.com/kata-containers/documentation/blob/master/how-to/how-to-use-kata-containers-with-acrn.md#pre-requisites
#. :ref:`ACRN supported hardware <hardware>`.
#. For default prebuilt ACRN binary in E2E package, You need have 4 CPUs cores or enable "CPU Hyper-Threading”
to have 4 CPU Thread for 2 CPU cores.
#. Follow this :ref:`instruction <quick-setup-guide>` to set up the ACRN Service VM.
#. Build ACRN kernel to enable ``macvtap`` function.
.. code-block:: none
$ git clone https://github.com/projectacrn/acrn-kernel.git
$ cd acrn-kernel
$ cp kernel_config_sos .config
$ sed -i "s/# CONFIG_MACVLAN is not set/CONFIG_MACVLAN=y/" .config
$ sed -i '$ i CONFIG_MACVTAP=y' .config
$ make clean && make olddefconfig && make && sudo make modules_install INSTALL_MOD_PATH=out/
Login Service VM, 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 && umount /mnt && sudo reboot
Configure Kata on ACRN
