I have been working in vCD for quite some time, and most of the implementation engineers or consultants faced issues during the deployment or upgrade of RabbitMQ for the vCD message queuing service. From vCD 10.2.2, we can use the built-in MQTT client instead of RabbitMQ however, for VCD multisite configuration or some 3rd party applications need RabbitMQ, such as Veeam or VMware HCX. Using the VCP LCM, we can create a new RabbitMQ environment or manage an existing environment. The reason for this blog is that none of the VMware documentation has the information that registering an existing RMQ instance is only going to work if the RMQ instance was previously deployed by the VCP LCM (or at least, if it is a similar setup based on a Bitnami RMQ VM). Other RMQ instances (e.g., running in CentOS) are not supported and cannot be imported into the VCP LCM 1.5. I hope this information will be useful for someone who is performing green field deployment or upgrading an existing setup.
