Unable to deploy VMs from Aria Automation to vCenter with IPv6

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

When deploying the machine from Aria automation with IPv6 network, IP is assigned correctly from vRA but not applied on the VM in vCenter.

Environment

VMware Aria Automation 8.x

Cause

Guest customization for IPv6 is only supported in a dual-stack configuration.

Single-stack IPv6 configurations will fail, as vCenter is designed to expect an IPv4 address during the customization process.

Note: This is a known limitation in vCenter.

Resolution

To work around this limitation, it is recommend to configure a dual-stack network profile by defining both IPv4 and IPv6 CIDR ranges in the network profile, and using the IPv6 range to assign IP addresses.

Note: In the blueprint code, it is required to set the property "assignIPv6Address" to true under machine component.

Sample blueprint:

formatVersion: 1
inputs: {}
resources:
  Cloud_vSphere_Machine_1:
    type: Cloud.vSphere.Machine
    properties:
      image: Test2

      networks:
        - network: ${resource.Cloud_vSphere_Network_1.id}
          assignment: static
          assignIPv6Address: true
