Using a ready-to-use Ubuntu Cloud-Init image

• Ubuntu 18.04 LTS (Bionic Beaver) Daily Build

• Steps for creating a template

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

# Create a VM
qm create 9000 --name ubuntu1804-templ --memory 2048 --net0 virtio,bridge=vmbr1

# Import the disk in qcow2 format (as unused disk) 
qm importdisk 9000 bionic-server-cloudimg-amd64.img local -format qcow2

# Attach the disk to the vm using VirtIO SCSI
qm set 9000 --scsihw virtio-scsi-pci --scsi0 /var/lib/vz/images/9000/vm-9000-disk-0.qcow2

# Important settings
qm set 9000 --ide2 local:cloudinit --boot c --bootdisk scsi0 --serial0 socket --vga serial0

# The initial disk is only 2GB, thus we make it larger
qm resize 9000 scsi0 +30G

# Using a  dhcp server on vmbr1 or use static IP
qm set 9000 --ipconfig0 ip=dhcp
#qm set 9000 --ipconfig0 ip=10.10.10.222/24,gw=10.10.10.1

# user authentication for 'ubuntu' user (optional password)
qm set 9000 --sshkey ~/.ssh/id_rsa.pub
#qm set 9000 --cipassword AweSomePassword

# check the cloud-init config
qm cloudinit dump 9000 user

# create tempalte and a linked clone
qm template 9000
qm clone 9000 190 --name ubuntu1804-1
qm start 190

rm -v bionic-server-cloudimg-amd64.img

• Login with: ssh [email protected]

To resize the VM disk later

qm shutdown 190 && qm wait
qm resize 190 scsi0 +8G
qm start 190

Checking cloud-init

• Cloud-init v.18.2: CLI subcommands | Ubuntu
• Directory layout — Cloud-Init 19.2 documentation
• Testing and debugging cloud-init — Cloud-Init 19.2 documentation cloud-localds(1) — cloud-image-utils — Debian testing — Debian Manpages

Convert Images

https://docs.openstack.org/image-guide/convert-images.html

qemu-img convert -f raw -O qcow2 bionic-server-cloudimg-amd64.img bionic-server-cloudimg-amd64.qcow2

worked just fine.
Thanks.

FYI, following your gist with recent images also works fine.
Just

wget https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64-disk-kvm.img
or
wget https://cloud.debian.org/images/cloud/bookworm/latest/debian-12-generic-amd64.qcow2

and adapt the file names where needed, and you're good to go;

How you manage to do this
# Import the disk in qcow2 format (as unused disk) qm importdisk 9000 bionic-server-cloudimg-amd64.img local -format qcow2

When local "storage: storage 'local' does not support vm images" ?

@electropolis You should be able to use local-lvm instead of local.
