For full details of the guest VM automation in Abiquo, see Guest setup
In Abiquo, the main implementation of cloud-init is using a Configuration Drive. The Configuration drive enables users to automate the configuration of a VM at first boot because it creates an ISO disk with user data files. Then Cloud-init or a similar system can configure the VM from the user data.
The Configuration drive feature can be used on VMs with private network or no network connectivity, because the VM pulls its own configuration from the ISO and there is no need for an external process to connect to the VM to configure it.
Configuration drive in Abiquo
When the user deploys the VM, Abiquo copies and uploads the configuration data to the hypervisor and attaches an ISO disk with this data to the VM. The ISO disk will count towards the limit of a maximum of 4 IDE drives per VM. At first boot, cloud-init configures the VM.
As part of this feature, the VM's Bootstrap script tab is now available in private cloud for cloud-init use only. Configuration drive is hypervisor agnostic and support for the bootstrap script depends on the configuration of cloud-init or another system on the VM template. However, cloud-init can also run other types of scripts, such as bash scripts.
