[cloud-init] Using Ubuntu 24.04 minimal image does not work

[Herman33]

I'm trying to get cloud init working with the Ubuntu 24.04 minimal image. The cloud init does not initiate at all it seems.

I'm using this image:
https://cloud-images.ubuntu.com/min...lease/ubuntu-24.04-minimal-cloudimg-amd64.img

When I switch to the full image (https://cloud-images.ubuntu.com/noble/current/noble-server-cloudimg-amd64.img) everything works as expected.

I've read somewhere (can't find the topic anymore) that this might be due to the minimal image not supporting cd-rom.

Is this the cause? And if so, is there a work-around?

This is the process I'm using to create my template:

qm create 8010 \
    --name "ubuntu-2404-ci" \
    --ostype l26 \
    --memory 1024 \
    --agent 1 \
    --bios ovmf \
    --machine q35 --efidisk0 local-lvm:0,pre-enrolled-keys=0 \
    --cpu host --socket 1 --cores 1 \
    --vga serial0 --serial0 socket  \
    --net0 virtio,bridge=vmbr0

# normal image (this one works)
#qm importdisk 8010 noble-server-cloudimg-amd64.img local-lvm

# minimal image (this one does not work)
qm importdisk 8010 ubuntu-24.04-minimal-cloudimg-amd64.img local-lvm

qm set 8010 --scsihw virtio-scsi-pci --virtio0 local-lvm:vm-8010-disk-1,discard=on
qm set 8010 --boot order=virtio0
qm set 8010 --ide2 local-lvm:cloudinit
qm set 8010 --cicustom "user=local:snippets/ci-ubuntu.yml"
qm set 8010 --ipconfig0 ip=dhcp

qm cloudinit update 8010

--bios ovmf \

qm set 8010 --ide2 local-lvm:cloudinit

Change your cloudinit drive to "scsi" from "ide"

Thanks for your quick answer, I got it working.

You've quoted the "--bios ovmf \" part too, should I change something there too?

No, the ovmf is fine - its the reason why you should use scsi. There is a compatibility problem between ovmf and ide. If you were to use legacy bios, then IDE is ok
