6.2. Creating New Virtual Machines

You can create a virtual machine in several ways:
  • From an existing template.
  • From the blank template. This is the same as creating a virtual machine from scratch.
  • As a clone from an existing template.


It is best practice to create a virtual desktop from an existing template. This is the easiest way to ensure that network, storage, processing and memory is set up correctly and efficiently. It is also the best way to set up multiple identical virtual desktops. Using identical virtual desktops is also the best way to make the most efficient use of storage.

6.2.1. Creating Virtual Machines from Existing Templates

You can create a virtual machine from an existing template (either created by you, or one that came with the system). A template is a base virtual machine that is set with a unique configuration and settings. A virtual machine that is based on a particular template acquires the configurations and settings of the template. Thus, templates are used to conveniently and efficiently create a set of identical virtual machines. By default, virtual machines created from templates use thin provisioning. In the context of templates, thin provisioning means that all virtual machines based on a given template share the same base image as the template and must remain on the same data domain as the template.
For a complete list of all the required settings to create a virtual machine, see Section 6.2.2, “Creating New Virtual Machines without a Template”.

To create a new virtual machine from an existing template:

  1. Click the Virtual Machines tab. The Virtual Machines tab displays a list of existing virtual machines.
    The icon to the right of the virtual machine name indicates whether it is a virtual server, a desktop or a part of a desktop pool.

  2. Click the New Desktop button.
    The New Desktop Virtual Machine dialog box displays.
  3. Select the Data Center and Host Cluster on which the desktop is to run. All templates that exist in the selected cluster display in the Based on Template list. Select an existing template.

  4. Enter a suitable Name and appropriate Description, and accept the default values inherited from the template in the rest of the fields. You can change them if needed. See Table 6.4, “New Virtual Machine Dialog Box Fields” for field descriptions.
  5. If you select a Windows Operating System, an additional Windows Sys Prep group displays on the New Virtual Machine dialog box.
  6. Click Stateless if the virtual machine is to run in stateless mode. A stateless desktop is always created from the base template, and deleted on shutdown. This type of virtual machine is very useful when creating virtual machines that need to be used for a short time, or by temporary staff
  7. Click OK to create the virtual machine. The virtual machine displays in the Virtual Machines list.


It may take some time for the virtual machine to be created. During this time, the status of the virtual machine displays as Image Locked, followed by Down.
