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 https://github.com/vmware-archive/cloud-init-vmware-guestinfo it is deprecated. It is now integrated natively into Cloud-Init Cloud-Init 21.3 has been released https://discourse.ubuntu.com/t/release-of-cloud-init-21-3/23857 which integrates this software.
