 = Configuring an IP address for a new virtual machine using cloud-init
 
-You can use cloud-init to configure an IP address when you create a virtual machine. The IP address can be dynamically or statically provisioned.
+You can use cloud-init to configure the IP address of a secondary NIC when you create a virtual machine (VM). The IP address can be dynamically or statically provisioned.
+
+[NOTE]
+====
+If the VM is connected to the pod network, the pod network interface is the default route unless you update it.
+====
+
+.Prerequisites
+
+* The virtual machine is connected to a secondary network.
+* You have a DHCP server available on the secondary network to configure a dynamic IP for the virtual machine.
 
 .Procedure
 
-* Create a virtual machine configuration and include the cloud-init network details in the `spec.volumes.cloudInitNoCloud.networkData` field of the virtual machine configuration:
+* Edit the `spec.template.spec.volumes.cloudInitNoCloud.networkData` stanza of the virtual machine configuration:
 
-.. To configure a dynamic IP, specify the interface name and the `dhcp4` boolean:
