VM Preparation

The VM template needs a few cloud-init tools installed before we can use it with cloud-init configs

Debian

[shroot]

apt install cloud-init cloud-initramfs-growroot

[/shroot]

Cloud-init

Cloud-init has a config file in /etc/cloud/cloud.cfg

Growing partitions

With growroot installed in the initramfs, cloud-init will expand partitions and filesystems to fit the root partition given.

XCP-ng: Set Hostname

This cloud config snippet sets the machine hostname to the VM name.

#cloud-config
hostname: {name}

Network config

The network config is a special config file with cloud-init that focuses on specifying network settings.

Set Static IP

The snippet below sets a static ip address for the specified interface.
Its syntax mainly follows the /etc/network/interfaces syntax.

network:
  version: 1
  config:
  - type: physical
    name: [INTERFACE]
    subnets:
      - type: static
        address: [ADDRESS]
        gateway: [ADDRESS]
        dns_nameservers: [ADDRESS]
