vCAC 6 series – Part 10 – Prepare for provisioning

There are several ways to deploy virtual machines with vCloud Automation Center 6.0 and vSphere.

Link Clone

Provision a space-efficient copy of a virtual machine called a linked clone. Linked clones are based on a snapshot of a VM and use a chain of delta disks to track differences from a parent machine. No required pre-provisioning preparations for link clone.


Provision machines by cloning from a template object created from an existing Windows or Linux machine (called the reference machine) and a customization specification

Flex Clone

Provision a space-efficient copy of a virtual machine by using NetApp FlexClone technology.

Preparing Linux and Windows VM for Flex Clone or Clone

When VM is deployed by flex clone or clone.

  • Navigate to the vCloud Automation Center Appliance management console installation page.
  • For example: https://vca01.lab.local:5480/installation.
  • Download and save the Windows guest agent files.
    • Windows guest agent files (32-bit.)
    • Windows guest agent files (64-bit.)



  • Unpack GugentZip_version in C:\ on the reference machine.
  • This produces the directory C:\VRMGuestAgent. Do not rename this directory.
  • Configure the guest agent by running the following command in an elevated command prompt: winservice -i -h Manager_Service_Hostname_fdqn[:portnumber -p ssl.
  • For example: winservice -i -h vca02.lab.local:443 -p ssl

  • After installation new service should appear in Windows Services called VCACGuestAgentService
  • Power server off and convert to template
  • Download package from vCAC appliance to Linux server
  • Unpack the LinuxGuestAgentPkgs file.
  • Navigate to the LinuxGuestAgentPkgs file and locate the subdirectory that corresponds to the guest operating system that you are deploying during provisioning.
  • Install the guest agent using the RPM package.
  • For example, rpm -i gugent-6.0.0-2025.x86_64.rpm.

  • Add agent installation path to $PATH

  • Change directory to /usr/share/gugent
  • Configure the guest agent to communicate with the Manager Service by running ./ -Manager_Service_Hostname_fdqn:portnumber ssl.
