  • Confusion about clone options (Linked Clone vs Full Clone)

  • New VM not appearing after cloning

  • Uncertainty about when a cloned VM is ready to start

Background

Proxmox allows administrators to create virtual machine templates that can be reused to quickly deploy new virtual machines. Cloning from a template saves time and ensures consistency across environments.

When cloning a VM, Proxmox provides options such as Linked Clone and Full Clone. For most standalone virtual machines, a Full Clone is recommended because it creates an independent copy that does not rely on the original template.

Prerequisites

  • You are logged in to the Proxmox web interface using valid credentials.

  • The Win11-Template (or another template) is visible in the left-hand navigation pane.

Solution

Follow the steps below to clone a virtual machine from a template in Proxmox.

1. Locate the Template

  • In the left-hand navigation pane, click on your Proxmox server name.

  • Scroll down the VM list and locate Win11-Template (it is usually near the bottom of the list).

  • Mode: Select Full Clone (recommended).

    Note: Linked Clone is not recommended for standalone virtual machines.
