|
|
Using Ubuntu as the Service OS
|
|
##############################
|
|
|
|
This document builds on the :ref:`getting_started`, and explains how to use
|
|
Ubuntu instead of using `Clear Linux`_ as the Service OS with the ACRN
|
|
hypervisor. (Note that different OSes can be used for the Service and User OS.)
|
|
In the following instructions we'll build on material in the
|
|
:ref:`getting-started-apl-nuc`.
|
|
|
|
Install Ubuntu (natively)
|
|
*************************
|
|
|
|
Ubuntu 16.04.4 LTS was used throughout this document, other versions such as
|
|
18.04 may work too.
|
|
|
|
* Download Ubuntu 16.04 from the `Ubuntu 16.04.4 LTS (Xenial Xerus) page
|
|
<https://www.ubuntu.com/download/desktop>`_ and select the `ubuntu-16.04.4-desktop-amd64.iso
|
|
<http://releases.ubuntu.com/16.04/ubuntu-16.04.4-desktop-amd64.iso>`_ image.
|
|
|
|
* Follow Ubuntu's `online instructions <https://tutorials.ubuntu.com/tutorial/tutorial-install-ubuntu-desktop?_ga=2.114179015.1954550575.1530817291-1278304647.1523530035>`_
|
|
to install it on your device.
|
|
|
|
.. note::
|
|
Configure your device's proxy settings to have full internet access.
|
|
|
|
* While not strictly required, enabling SSH gives the user a very useful
|
|
mechanism for accessing the Service OS remotely or when running one or more
|
|
User OS (UOS). Follow these steps to enable it on the Ubuntu SOS:
|
|
|
|
.. code-block:: none
|
|
|
|
sudo apt-get install openssh-server
|
|
sudo service ssh status
|
|
sudo service ssh start
|
|
|
|
Install ACRN
|
|
************
|
|
|
|
ACRN components are distributed in source form, so you'll need to download
|
|
the source code, build it, and install it on your device.
|
|
|
|
1. Install the build tools and dependencies
|
|
|
|
Follow the instructions found in the :ref:`getting-started-apl-nuc` to
|
|
install all the build tools and dependencies on your system.
|
|
|
|
#. Clone the `Project ACRN <https://github.com/projectacrn/acrn-hypervisor>`_
|
|
code repository
|
|
|
|
.. code-block:: none
|
|
|
|
cd ~
|
|
git clone https://github.com/projectacrn/acrn-hypervisor
|
|
git checkout <known-good-tag/release>
|
|
|
|
.. note::
|
|
We clone the git repository below but it is also possible to download the
|
|
tarball for any specific tag or release from the `Project ACRN Github
|
|
release page <https://github.com/projectacrn/acrn-hypervisor/releases>`_
|
|
|
|
#. Build and install ACRN
|
|
|
|
Here is the short version of how to build and install ACRN from source.
|
|
|
|
.. code-block:: none
|
|
|
|
cd ~/acrn-hypervisor
|
|
make PLATFORM=uefi
|
|
sudo make install
|
|
|
|
For more details, please refer to the :ref:`getting-started-apl-nuc`.
|
|
|
|
#. Install the hypervisor
|
|
|
|
The ACRN devicemodel and tools were installed as part of the previous step.
|
|
However, ``make install`` does not install the hypervisor (``acrn.efi``) on
|
|
your EFI System Partition (ESP), nor does it configure your EFI firmware to
|
|
boot it automatically. Follow the steps below to perform these operations
|
|
and complete the ACRN installation.
|
|
|
|
#. Mount the EFI System Partition (ESP) and add the ACRN hypervisor and
|
|
Service OS kernel to it (as ``root``)
|
|
|
|
.. code-block:: none
|
|
|
|
sudo umount /boot/efi
|
|
sudo lsblk
|
|
sudo mount /dev/sda1 /mnt
|
|
ls /mnt/EFI/ubuntu
|
|
|
|
You should see the following output:
|
|
|
|
.. code-block:: none
|
|
|
|
fw fwupx64.efi grub.cfg grubx64.efi MokManager.efi shimx64.efi
|
|
|
|
#. Install the hypervisor (``acrn.efi``)
|
|
|
|
.. code-block:: none
|
|
|
|
sudo mkdir /mnt/EFI/acrn/
|
|
sudo cp ~/acrn-hypervisor/build/hypervisor/acrn.efi /mnt/EFI/acrn
|
|
|
|
#. Configure the EFI firmware to boot the ACRN hypervisor by default
|
|
|
|
.. code-block:: none
|
|
|
|
sudo efibootmgr -c -l "\EFI\acrn\acrn.efi" -d /dev/sda -p 1 \
|
|
-L "ACRN Hypervisor" -u "bootloader=\EFI\ubuntu\grubx64.efi"
|
|
|
|
#. Verify that the "ACRN Hypervisor" is added and make sure it will be booted first
|
|
|
|
.. code-block:: none
|
|
|
|
sudo efibootmgr -v
|
|
|
|
#. You can change the boot order at any time using ``efibootmgr
|
|
-o XXX,XXX,XXX``
|
|
|
|
.. code-block:: none
|
|
|
|
sudo efibootmgr -o xxx,xxx,xxx
|
|
|
|
.. note::
|
|
By default, the “ACRN Hypervisor” you have just added should be
|
|
the first one to boot. Verify this by using ``efibootmgr -v`` or
|
|
by entering the EFI firmware at boot (using :kbd:`F10`)
|
|
|
|
Install the Service OS kernel
|
|
*****************************
|
|
|
|
You can download latest Service OS kernel from
|
|
`<https://download.clearlinux.org/releases/current/clear/x86_64/os/Packages/>`_
|
|
|
|
1. The latest Service OS kernel from the latest Clear Linux release
|
|
from this area:
|
|
https://download.clearlinux.org/releases/current/clear/x86_64/os/Packages. Look for an
|
|
``.rpm`` file named ``linux-pk414-sos-<kernel-version>-<build-version>.x86_64.rpm``.
|
|
|
|
While we recommend using the "current" (latest) release of Clear Linux, you can download
|
|
a specific Clear Linux release from an area with that release number, e.g.:
|
|
https://download.clearlinux.org/releases/24040/clear/x86_64/os/linux-pk414-sos-4.14.57-69.x86_64.rpm
|
|
|
|
#. Download and extract the latest Service OS kernel(this guide is based on 24040 as the current example)
|
|
|
|
.. code-block:: none
|
|
|
|
mkdir ~/kernel-build
|
|
cd ~/kernel-build
|
|
wget https://download.clearlinux.org/releases/24040/clear/x86_64/os/Packages/linux-pk414-sos-4.14.57-69.x86_64.rpm
|
|
sudo apt-get install rpm2cpio
|
|
rpm2cpio linux-pk414-sos-4.14.57-69.x86_64.rpm | cpio -idmv
|
|
|
|
#. Install the SOS kernel and its drivers (modules)
|
|
|
|
.. code-block:: none
|
|
|
|
sudo cp -r ~/kernel-build/usr/lib/modules/4.14.57-69.pk414-sos/ /lib/modules/
|
|
sudo cp ~/kernel-build/usr/lib/kernel/org.clearlinux.pk414-sos.4.14.57-69 /boot/acrn/
|
|
|
|
#. Configure Grub to load the Service OS kernel
|
|
|
|
* Modify the ``/etc/grub.d/40_custom`` file to create a new Grub entry that
|
|
will boot the SOS kernel.
|
|
|
|
.. code-block:: none
|
|
|
|
menuentry 'ACRN ubuntu SOS' {
|
|
recordfail
|
|
load_video
|
|
insmod gzio
|
|
insmod part_gpt
|
|

|
|

|
|
}
|
|
|
|
.. note::
|
|
You need to adjust this to use your partition UUID (``PARTUUID``) for
|
|
the ``root=`` parameter (or use the device node directly).
|
|
|
|
.. note::
|
|
You will also need to adjust the kernel name if you used a different
|
|
RPM file as the source of your Service OS kernel.
|
|
|
|
.. note::
|
|
The command line for the kernel in /etc/grub.d/40_custom should be all
|
|
as a single line, not as multiple lines. Otherwise the kernel will fail to boot
|
|
|
|
* Modify the ``/etc/default/grub`` file to make the grub menu visible when booting.
|
|
There are a couple of lines to be modified, as shown below.
|
|
|
|
.. code-block:: none
|
|
|
|
#GRUB_HIDDEN_TIMEOUT=0
|
|
GRUB_HIDDEN_TIMEOUT_QUIET=false
|
|
|
|
* Update Grub on your system
|
|
|
|
.. code-block:: none
|
|
|
|
sudo update-grub
|
|
|
|
#. Reboot the system
|
|
|
|
Reboot system. You should see the Grub menu with the new “ACRN ubuntu SOS”
|
|
entry. Select it and proceed to booting the platform. The system will start
|
|
the Ubuntu Desktop and you can now log in (as before).
|
|
|
|
.. note::
|
|
If you don't see the Grub menu after rebooting the system (and you're
|
|
not booting into the ACRN hypervisor), you'll need to enter the
|
|
EFI firmware at boot (using :kbd:`F10`) and manually select ``ACRN Hypervisor``.
|
|
|
|
.. note::
|
|
If you see a black screen on the first-time reboot after installing the ACRN Hypervisor,
|
|
wait a few moments and the Ubuntu desktop will be displayed.
|
|
|
|
To check if the hypervisor is effectively running, check ``dmesg``. The
|
|
typical output of a successful installation will look like this:
|
|
|
|
.. code-block:: none
|
|
|
|
dmesg | grep ACRN
|
|
[ 0.000000] Hypervisor detected: ACRN
|
|
[ 0.862942] ACRN HVLog: acrn_hvlog_init
|
|
|
|
Prepare the User OS (UOS)
|
|
*************************
|
|
|
|
For the User OS, we are using the same `Clear Linux`_ release version as the Service OS.
|
|
|
|
* Download the Clear Linux image from `<https://download.clearlinux.org>`_
|
|
|
|
.. code-block:: none
|
|
|
|
cd ~
|
|
wget https://download.clearlinux.org/releases/24040/clear/clear-24040-kvm.img.xz
|
|
unxz clear-24040-kvm.img.xz
|
|
|
|
* Download the Production Kernel (PK) kernel
|
|
|
|
.. code-block:: none
|
|
|
|
wget https://download.clearlinux.org/releases/24040/clear/x86_64/os/Packages/linux-pk414-standard-4.14.57-69.x86_64.rpm
|
|
rpm2cpio linux-pk414-standard-4.14.57-69.x86_64.rpm | cpio -idmv
|
|
|
|
* Update the UOS kernel modules
|
|
|
|
.. code-block:: none
|
|
|
|
sudo losetup -f -P --show /root/clear-24040-kvm.img
|
|
sudo mount /dev/loop0p3 /mnt
|
|
sudo cp -r /root/usr/lib/modules/4.14.57-69.pk414-standard /mnt/lib/modules/
|
|
sudo cp -r /root/usr/lib/kernel /lib/modules/
|
|
sudo umount /mnt
|
|
sync
|
|
|
|
If you encounter a permission issue, follow these steps:
|
|
|
|
.. code-block:: none
|
|
|
|
sudo chmod 777 /dev/acrn_vhm
|
|
|
|
* One additional package is needed
|
|
|
|
.. code-block:: none
|
|
|
|
sudo apt-get install iasl
|
|
sudo cp /usr/bin/iasl /usr/sbin/iasl
|
|
|
|
* Adjust ``launch_uos.sh``
|
|
|
|
You need to adjust the ``/usr/share/acrn/samples/nuc/launch_uos.sh`` script
|
|
to match your installation. These are the couple of lines you need to modify:
|
|
|
|
.. code-block:: none
|
|
|
|
-s 3,virtio-blk,/root/clear-24040-kvm.img
|
|
-k /lib/modules/kernel/org.clearlinux.pk414-standard.4.14.57-69
|
|
|
|
Start the User OS (UOS)
|
|
***********************
|
|
|
|
You are now all set to start the User OS (UOS)
|
|
|
|
.. code-block:: none
|
|
|
|
sudo /usr/share/acrn/samples/nuc/launch_uos.sh
|
|
|
|
**Congratulations**, you are now watching the User OS booting up!
|
|
|
|
|
|
Enabling network sharing
|
|
************************
|
|
|
|
After booting up the SOS and UOS, network sharing must be enabled to give network
|
|
access to the UOS by enabling the TAP and networking bridge in the SOS. The following
|
|
script example shows how to set this up (verified in Ubuntu 14.04 and 16.04 as the SOS).
|
|
|
|
|
|
.. code-block:: none
|
|
|
|
#!/bin/bash
|
|
#setup bridge for uos network
|
|
br=$(brctl show | grep acrn-br0)
|
|
br=${br-:0:6}
|
|
ip tuntap add dev acrn_tap0 mode tap
|
|
|
|
taps=$(ifconfig | grep acrn_ | awk '{print $1}')
|
|
|
|
# if bridge not existed
|
|
if [ "$br"x != "acrn-br0"x ]; then
|
|
#setup bridge for uos network
|
|
brctl addbr acrn-br0
|
|
brctl addif acrn-br0 enp3s0
|
|
ifconfig enp3s0 0
|
|
dhclient acrn-br0
|
|
# add existing tap devices under the bridge
|
|
for tap in $taps; do
|
|
ip tuntap add dev acrn_$tap mode tap
|
|
brctl addif acrn-br0 $tap
|
|
ip link set dev $tap down
|
|
ip link set dev $tap up
|
|
done
|
|
fi
|
|
|
|
brctl addif acrn-br0 acrn_tap0
|
|
ip link set dev acrn_tap0 up
|
|
|
|
.. note::
|
|
The SOS network interface is called ``enp3s0`` in the script above. You will need
|
|
to adjust the script if your system uses a different name (e.g. ``eno1``).
|
|
|
|
Enabling USB keyboard and mouse
|
|
*******************************
|
|
|
|
Please refer to :ref:`getting-started-apl-nuc` for enabling the
|
|
USB keyboard and mouse for the UOS.
