Automatic installation quick start for s390x
|
|
********************************************
|
|
|
|
This how-to provides basic instructions to perform an automatic installation
|
|
in a virtual machine (VM) on a local machine on the s390x architecture.
|
|
|
|
This how-to is a version of :ref:`autoinstall_quickstart`.
|
|
adapted for s390x.
|
|
|
|
Download an ISO
|
|
===============
|
|
|
|
Download an ISO image of the latest release from the `release page <https://cdimage.ubuntu.com/ubuntu/releases/>`_ (currently |ubuntu-latest-version| (|ubuntu-latest-codename|)).
|
|
|
|
.. parsed-literal::
|
|
|
|
wget https:\ //cdimage.ubuntu.com/ubuntu/releases/|ubuntu-latest-version|/release/ubuntu-|ubuntu-latest-version|-live-server-s390x.iso -P ~/Downloads
|
|
|
|
Mount the ISO
|
|
=============
|
|
|
|
.. parsed-literal::
|
|
|
|
mkdir -p ~/iso
|
|
sudo mount -r ~/Downloads/ubuntu-|ubuntu-latest-version|-live-server-s390x.iso ~/iso
|
|
|
|
Write your autoinstall configuration
|
|
====================================
|
|
|
|
Create a cloud-init configuration:
|
|
|
|
.. code-block:: none
|
|
|
|
mkdir -p ~/www
|
|
cd ~/www
|
|
cat > user-data << 'EOF'
|
|
#cloud-config
|
|
autoinstall:
|
|
version: 1
|
|
identity:
|
|
hostname: ubuntu-server
|
|
password: "$6$exDY1mhS4KUYCE/2$zmn9ToZwTKLhCw.b4/b.ZRTIZM30JZ4QrOQ2aOXJ8yk96xpcCof0kxKwuX1kqLG/ygbJ1f8wxED22bTL4F46P0"
|
|
username: ubuntu
|
|
EOF
|
|
touch meta-data
|
|
|
|
The encrypted password is ``ubuntu``.
|
|
|
|
Serve the cloud-init configuration over HTTP
|
|
============================================
|
|
|
|
Leave this running in one terminal window:
|
|
|
|
.. code-block:: none
|
|
|
|
cd ~/www
|
|
python3 -m http.server 3003
|
|
|
|
Create a target disk
|
|
====================
|
|
|
|
Proceed with a second terminal window:
|
|
|
|
.. code-block:: none
|
|
|
|
sudo apt install qemu-utils
|
|
...
|
|
|
|
qemu-img create -f qcow2 disk-image.qcow2 10G
|
|
Formatting 'disk-image.qcow2', fmt=qcow2 size=10737418240 cluster_size=65536 lazy_refcounts=off refcount_bits=16
|
|
|
|
qemu-img info disk-image.qcow2
|
|
image: disk-image.qcow2
|
|
file format: qcow2
|
|
virtual size: 10 GiB (10737418240 bytes)
|
|
disk size: 196 KiB
|
|
cluster_size: 65536
|
|
Format specific information:
|
|
compat: 1.1
|
|
lazy refcounts: false
|
|
refcount bits: 16
|
|
corrupt: false
|
|
|
|
Run the installation
|
|
====================
|
|
|
|
.. code-block:: none
|
|
|
|
sudo apt install qemu-kvm
|
|
...
|
|
|
|
Add the default user to the ``kvm`` group:
|
|
|
|
.. code-block:: none
|
|
|
|
sudo usermod -a -G kvm ubuntu # re-login to make the changes take effect
|
|
|
|
kvm -no-reboot -name auto-inst-test -nographic -m 2048 \
|
|
-drive file=disk-image.qcow2,format=qcow2,cache=none,if=virtio \
|
|
-cdrom ~/Downloads/ubuntu-22.10-live-server-s390x.iso \
|
|
-kernel ~/iso/boot/kernel.ubuntu \
|
|
-initrd ~/iso/boot/initrd.ubuntu \
|
|
-append 'autoinstall ds=nocloud-net;s=http://_gateway:3003/ console=ttysclp0'
|
|
|
|
The above commands boot the virtual machine, download the configuration from the server
|
|
(prepared in the previous step) and run the installation.
|
|
|
|
The installer reboots at the end. The ``-no-reboot`` flag to ``kvm`` instructs ``kvm``
|
|
to terminate on reboot. The procedure takes approximately 5 minutes.
|
|
|
|
Boot the installed system
|
|
=========================
|
|
|
|
.. code-block:: none
|
|
|
|
kvm -no-reboot -name auto-inst-test -nographic -m 2048 \
|
|
-drive file=disk-image.qcow2,format=qcow2,cache=none,if=virtio
|
|
|
|
This command boots into the installed system. Log in using ``ubuntu`` for both the user
|
|
name and password.
