An administrator wants to clone a virtual machine using the vSphere Client. Which explains why the Clone option is missing?

VM cloning is a vCenter Server-level feature and is not available when the vSphere Client connects directly to a standalone ESXi host. vCenter Server provides the orchestration layer needed to manage clone operations, including copying disk files and registering the new VM. Without vCenter, the Clone menu option is simply not exposed in the client.

Thin provisioning affects storage allocation behavior but has no impact on the availability of the Clone option in the vSphere Client interface.

Outdated virtual hardware version may limit certain VM features but does not prevent the Clone option from appearing; it is the connection target (ESXi vs. vCenter) that matters.

Cloning can be performed through the vSphere Client connected to vCenter Server; vRealize Orchestrator is an automation platform and is not required to perform cloning operations.
