Environment

VMware Cloud Director 10.6.0.1

Cause

Provider VDC of the concerned OrgVDC is backed by more than one cluster and one of the cluster has DRS disabled. VMware Cloud Director supports the power on function of VMs only when the DRS automation level is Fully Automated or Partially Automated.

Resolution

As per VCD's requirements, enable the DRS on the Cluster.
