As a vCenter Server administrator, you want to prepare a vSphere template that your vRealize Automation architects can use to clone Linux CentOS machines. You want to ensure that your template supports blueprints with software components, so you install the guest agent and the software bootstrap agent before you turn your reference machine into a template.


  • Identify or create a Linux CentOS reference machine with VMware Tools installed. Include at least one Network Adapter to provide internet connectivity in case blueprint architects do not add this functionality at the blueprint level. For information about creating virtual machines, see the vSphere documentation.

  • You must be connected to a vCenter Server to convert a virtual machine to a template. You cannot create templates if you connect the vSphere Client directly to an vSphere ESXi host.


You created a template and customization specification from your reference machine that blueprint architects can use to create vRealize Automation blueprints that clone Linux CentOS machines. Because you installed the Software bootstrap agent and the guest agent on your reference machine, architects can use your template to create elaborate catalog item blueprints that include Software components or other guest agent customizations such as running scripts or formatting disks. Because you installed VMware Tools, architects and catalog administrators can allow users to perform actions against machines, such as reconfigure, snapshot, and reboot.

What to do next

After you configure vRealize Automation users, groups, and resources, you can use your template and customization specification to create a machine blueprint for cloning. See Scenario: Create a vSphere CentOS Blueprint for Cloning in Rainpole.
