After initiating a deletion request from VMware Cloud Director, powered-off virtual machines (VMs) may still be visible within the vCenter Server inventory.
This is the expected architectural behavior for VM templates residing in a VMware Cloud Director catalog. VMware Cloud Director provisions and stores catalog items (vApp and VM templates) as powered-off virtual machines within the underlying vCenter Server infrastructure. Unless the templates are deleted from the VCD catalog itself, they remain in the inventory.
No technical remediation is required as this is expected behavior. To remove the VMs from the vCenter inventory, delete the corresponding vApp or VM templates from the VMware Cloud Director catalog.
For guidance on managing catalog items, refer to Working with Catalogs in the VMware Cloud Director Tenant Portal
