Cloud-Init for VMs in private and public Clouds

Initialize VMs in a vSphere private Cloud using Cloud-Init

Cloud-Init Datasource for VMware GuestInfo is deprecated

The Web is full of explanations, how to use „Cloud-Init Datasource for VMware GuestInfo“ but it is deprecated.

It is now integrated natively into Cloud-Init

Cloud-Init 21.3 has been released which integrates this software.

New name:

I’d expect it to be in the current Ubuntu 21.10 (Impish Indri) – the release notes for 21.10 don’t specify the exact version.

Ubuntu 20.04 (Focal Fossa) is still at cloud-init 20.1-10 according to which is too old.

Prepare a VM-Template

Unfortunately Ubuntu provides the „cloud“-images in OVA-Format.

Create VM-Template from OVA


  • impish-server-cloudimg-amd64.ova


  • VM
  • keep all settings set to default

Customize VM

  • disable (or remove) the „Serial“-port
  • disable vApp-Properties
    • those would break the cloud-init process later on
    • VM=>Configure
    • Settings=>vApp-Options
    • disable [ ] vApp-Properties

Convert to Template

  • VM-Template „ubuntu-impish-21.10-cloudimg“.

Clone a VM from this VM-Template

This shouldn’t be done manually, I’d suggest using terraform

Verify that Cloud-Init 21.3 is available and the „VMware“-Datasource is included

Cloud-Init Version

Release 21.3 is available:

ubuntu@ubuntu:~$ cloud-init --version
/usr/bin/cloud-init 21.3-1-g6803368d-0ubuntu3

Check the Cloud-Init Datasource

Datasource „vmware“ is included:

ubuntu@ubuntu:~$ cloud-id
