Cloud-Init¶

The following provides instructions on creating a Cloud-Init ready Ubuntu 24.04 template using Proxmox. These instructions were derived from Proxmox Cloud-Init Support documentation.

These steps have been automated using the cloudinit role.

SSH Into A Proxmox Server¶

The subsequent commands will be executed inside the proxmox server that will host the template. Therefore, first connect to the server's console.

ssh 192.168.2.202

Download Ubuntu 24 Cloud-Init Image¶

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

Create a new VM with VirtIO SCSI controller¶

qm create 9500 --memory 2048 --net0 virtio,bridge=vmbr0 --scsihw virtio-scsi-pci

Attached the Disk Image to the VM¶

The following command will import the downloaded image into the Proxmox cluster shared storage, linstor_storage, and attach it to the VM's SCSI drive.

qm set 9500 --scsi0 linstor_storage:0,import-from=/root/noble-server-cloudimg-amd64.img

Add Cloud-Init CD-ROM drive¶

The next step is to configure a CD-ROM drive, which will be used to pass the Cloud-Init data to the VM.

qm set 9500 --ide2 linstor_storage:cloudinit

Restrict Boot to SCSI Device¶

To be able to boot directly from the Cloud-Init image, set the boot parameter to order=scsi0 to restrict BIOS to boot from this disk only. This will speed up booting, because VM BIOS skips the testing for a bootable CD-ROM.

qm set 9500 --boot order=scsi0

Serial Console¶

For many Cloud-Init images, it is required to configure a serial console and use it as a display. If the configuration doesn’t work for a given image however, switch back to the default display instead.

qm set 9500 --serial0 socket --vga serial0

Convert to Template¶

qm template 9500
