 +===== Disable cloud-init =====
 +<code bash>
 +sudo touch /etc/cloud/cloud-init.disabled
 +sudo echo "network: {config: disabled}" > /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg

 +Also update this
 +<code>
 +FCheck for the existence of /etc/cloud/cloud.cfg configuration. If the file exists edit the file and change the settings within:
 +FROM:
 +preserve_hostname: false
 +TO:
 +preserve_hostname: true
 +</code>

 +===== Hostname Chage =====
 +<code bash>
 +sudo hostnamectl set-hostname NEWHOSTNAME
 +</code>
 +
 +===== Network configuration (multiple networks) =====
 +In this case a Bridge network on 192.168.1.1/24 and a host-only network on 192.168.56.1/24.  Most important is the absence of the gateway4 line in the host-only network to ensure internet traffic goes via 192.168.1.1 gateway.
