Create virtual machine template

Here are the instructions on how to create a virtual machine template using vSphere Web Client:

1. Go to the VMs And Templates inventory view. Right-click the VM you want to use as a template and select All vCenter Actions > Clone to Template or All vCenter Actions > Convert to Template. Both options will create a template, but the original VM will be retained only if you use the Clone to Template option:

2a. If you’ve selected the Convert to Template option, you should see the template in the Inventory. Note that the original virtual machine was not retained:

2b. If you’ve selected the Clone to Template option, the wizard should open. Type the template name and select the location for the template:

clone to template

Select the host or cluster where the template will be hosted:

clone to template compute resource

Select the disk format for the template. Four options are available:

  • Same format as source – keeps the template’s virtual disks in the same format as the VM that is being cloned.
  • Thick Provision Lazy Zeroed – the disk space will be fully allocated when the virtual disk is created. The disk space will not be zeroed out upon creation.
  • Thick Provision Eager Zeroed – the disk space will be fully allocated when the virtual disk is created. The disk space will be zeroed out upon creation.
  • Thin Provision – the virtual disks will occupy only as much space as is currently used by the guest OS.

Review the information and click Finish:

You should see the template in the Inventory. Note that the original virtual machine is retained:

Unlike the Clone to Template option, the Covert to Template option doesn’t offer a choice of format in which to store the VM’s virtual disks and leaves the VM disk files intact.
