Deploying a virtual machine from a template creates a new virtual machine that is a copy of the template. The new virtual machine has the virtual hardware, installed software, and other properties configured for the template.

You must be connected to vCenter Server to deploy a virtual machine from a template. You cannot deploy from a template if you connect the vSphere Client directly to an ESX/ESXi host.

To customize the guest operating system of the virtual machine, check that your guest operating system meets the requirements for customization. See Guest Operating System Customization Requirements.

To use a customization specification, you must first create or import the customization specification.

To use a custom script to generate the host name or IP address for the new virtual machine, configure the script. See Configure a Script to Generate Computer Names and IP Addresses During Guest Operating System Customization.

1

Right-click the template, and select Deploy Virtual Machine from this Template.

2

Enter a virtual machine name, select a location, and click Next.

3

Select a host or cluster on which to run the new virtual machine.

Option

Description

Run the virtual machine on a standalone host.

Select the host and click Next.

Run the virtual machine in a cluster with DRS automatic placement.

Select the cluster and click Next.

Run the virtual machine in a cluster without DRS automatic placement.

a

Select the cluster and click Next.

b

Select a host within the cluster and click Next.

4

Select a resource pool in which to run the clone and click Next.

5

Select the datastore location where you want to store the virtual machine files and click Next.

Option

Description

Store all virtual machine files in the same location.

Select a datastore and click Next.

a

Click Advanced.

b

For the virtual machine configuration file and for each virtual disk, select a datastore from the drop-down list.

c

Click Next.

6

Select the format for the virtual machine's disks and click Next.

Option

Description

Same format as source

Use the same format as the source virtual machine.

Thin provisioned format

Use the thin provisioned format. At first, a thin provisioned disk uses only as much datastore space as the disk initially needs. If the thin disk needs more space later, it can grow to the maximum capacity allocated to it.

Only VMFS datastore version 3 and later support virtual disks in the thin provisioned format.

Thick format

The thick virtual disk does not change its size and from the very beginning occupies the entire datastore space provisioned to it.

7

Select a guest operating system customization option.

Option

Description

Do not customize

Select Do not customize and click Next.

Does not customize any of the guest operating system settings. All settings remain identical to those of the source virtual machine.

Customize using the Customization Wizard

Select this option and click Finish.

The virtual machine powers on after the deployment task completes.

Edit virtual hardware

a

Select Edit virtual hardware and click Continue.

b

In the Virtual Machine Properties dialog box, make any changes that you want to make and click OK.

The virtual machine is deployed. You cannot use or edit the virtual machine until the deployment is complete. This might take several minutes if the deployment involves creating a virtual disk.
