How to create your lab template ?

Assuming that you need to create a virtual Lab based on the GNS3 tool, handled by the OS Ubunut 18.

In the lab template page,  click on the Create button at the top-right corner of the screen:

You will be directed to the Template Lab Creation screen:

First, select a template source that can be either basic or extended template. The template to be selected in the list is Ubuntu-18-base-OS.

PS: If the source’s list is empty (first use) or the required basic template does not exist in the list, you can import it from the Clover’s catalog (click here for importing template).

Next, enter your template name (for instance GNS3) and description.

Finally, in the Metadata section, you may select and modify additional options by:

  • Defining a new VM size, if needed, different from the default one (in terms of vCPU, vRAM and vDisk). All virtual desktops created from the template will have the same size. You can change the flavor later from the Template List -> actions -> Edit Template
  • Selecting the access Mode (RDP for remote desktop access) or SSH to emulate a terminal on the server side and draws the screen of this terminal remotely on the client)
  • Determining if the desktop is persistent or not. A persistent virtual desktop is one in which a user will be able to keep all the configurations and personalization they have created from session to session. Non-persistent desktops are stateless.

Click on the Create button to start the template creation process. Clover creates a new virtual desktop based on the template’s image with respect to the size, policies and settings defined in the template. A progress bar indicates the creation status:

Once the VM created, the template status will be marked as WaitingForConfirmation. Click on the button Actions->Display Template to access the VM (a temporary instance of the template):

You can now install and configure your VM. In this example you should install GNS3.  Check that all configurations and settings are going well before confirming the template.

Move back to the Template List and click the button  Actions ->Confirm Template



Once confirmed, a snapshot of the VM will be created and attached to the template.  The template status changes to Active when ready. You can edit some information about your template by clicking on Actions ->Edit Template


Congratulations ! Your Template is successfully created.  You can now link it to your course unit.
