Libvirt is a tool for managing virtual machines and containers.

Create your configuration¶

In this example we will create empty network-config and meta-datafiles, and create a user-data file with a basic cloud-init configuration.

If you have network configuration or metadata to provide, edit thenetwork-config and meta-data files accordingly.

To create the files, run the following commands:

$ touch network-config $ touch meta-data $ cat >user-data <<EOF #cloud-config password: password chpasswd: expire: False ssh_pwauth: True EOF

Download a cloud image¶

Download an Ubuntu image to run:

wget https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64.img

Create an instance¶

virt-install --name cloud-init-001 --memory 4000 --noreboot
--os-variant detect=on,name=ubuntujammy
--disk=size=10,backing_store="$(pwd)/jammy-server-cloudimg-amd64.img"
--cloud-init user-data="$(pwd)/user-data,meta-data=$(pwd)/meta-data,network-config=$(pwd)/network-config"
