Autoinstall quick start for s390x
|
|
*********************************
|
|
|
|
The intent of this page is to provide simple instructions to perform an
|
|
autoinstall in a VM on your machine on s390x.
|
|
|
|
This page is just a slightly adapted page of the
|
|
`autoinstall quickstart page<autoinstall_quickstart>` mapped to s390x.
|
|
|
|
Download an ISO
|
|
===============
|
|
|
|
At the time of writing (just after the Kinetic release), the best place to go
|
|
is here:
|
|
https://cdimage.ubuntu.com/ubuntu/releases/22.10/release/
|
|
|
|
..code-block:: bash
|
|
|
|
wget https://cdimage.ubuntu.com/ubuntu/releases/22.10/release/ubuntu-22.10-live-server-s390x.iso -P ~/Downloads
|
|
|
|
Mount the ISO
|
|
=============
|
|
|
|
.. code-block:: bash
|
|
|
|
mkdir -p ~/iso
|
|
sudo mount -r ~/Downloads/ubuntu-22.10-live-server-s390x.iso ~/iso
|
|
|
|
Write your autoinstall config
|
|
=============================
|
|
|
|
This means creating cloud-init config as follows:
|
|
|
|
.. code-block:: bash
|
|
|
|
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 crypted password is just ``ubuntu``.
|
|
|
|
Serve the cloud-init config over HTTP
|
|
=====================================
|
|
|
|
Leave this running in one terminal window:
|
|
|
|
.. code-block:: bash
|
|
|
|
cd ~/www
|
|
python3 -m http.server 3003
|
|
|
|
Create a target disk
|
|
====================
|
|
|
|
Proceed with a second terminal window:
|
|
|
|
.. code-block:: bash
|
|
|
|
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 install!
|
|
================
|
|
|
|
.. code-block:: bash
|
|
|
|
sudo apt install qemu-kvm
|
|
...
|
|
|
|
You may need to add the default user to the ``kvm`` group: <<BR>>
|
|
|
|
.. code-block:: bash
|
|
|
|
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'
|
|
|
|
This will boot, download the config from the server (set up in the previous
|
|
step) and run the install.
|
|
|
|
The installer reboots at the end but the ``-no-reboot`` flag to ``kvm`` means
|
|
that ``kvm`` will exit when this happens. It should take about 5 minutes.
|
|
|
|
Boot the installed system
|
|
=========================
|
|
|
|
.. code-block:: bash
|
|
|
|
kvm -no-reboot -name auto-inst-test -nographic -m 2048 \
|
|
-drive file=disk-image.qcow2,format=qcow2,cache=none,if=virtio
|
|
|
|
This will boot into the freshly installed system and you should be able to log
|
|
in as ``ubuntu/ubuntu``.
