We are created the one operational workflow for VM provisioning. Also, we have added the hosts in KVM clouds. Once VM gets provisioned we are planned to create other automation tasks to install the Morpheus agent and then convert that machine into managed instance using Morpheus API.As I checked the get instances Morpheus API its only retrieving the information of managed one however, we needed the instance id for managed instance conversion API.
You should be able to provision systems natively without the need for an operational workflow.
With that said, you need to look at the servers API to make a system managed and/or install the agent. Instances are already managed machines.
