Customizing Virtual Machine Templates
for VMware and Hyper-V
ASM supports cloning virtual machines (VM) or virtual machine templates in VMware, and cloning virtual
machine templates in Hyper-V. For ASM virtual machine or virtual machine template cloning, the virtual
machine or virtual machine templates must be customized to make sure virtual machine or virtual
machine templates have a unique identifier and can communicate back to the ASM appliance upon
completion of the cloning process. This requires several customizing steps that depends on virtual
machine which is needed to be cloned.
Customizing Virtual Machine Templates or Virtual
Machines for VMware or Hyper-V
ASM can clone existing virtual machines and virtual machine templates in vCenter, or virtual machine
templates in Hyper-V. The source virtual machines and virtual machine templates must be customized
according to the instructions provided in this section. After customization, you must shut down the virtual
machine and you cannot restart the virtual machine. For VMware virtual machines or virtual machine
templates, cloning is supported as long as you are cloning within the same datacenter. For SCVMM the
virtual machine templates must exist in the SCVMM library. Cloning virtual machines directly is not
currently supported for Hyper-V.
NOTE: After customization, if you restart the virtual machines, the virtual machine will no longer be
valid for cloning, and in that case, the verification file must be deleted. See later in this section about
deleting the verification file.
The following customization is required only for VMware virtual machines:
Install VMWare Tools on the virtual machine:
• If the virtual machine being used does not have a DVD drive, you must add one. To do this, edit the
settings of the virtual machine and add a DVD drive through your VMware management console.
• Once a DVD drive is available, right-click the virtual machine and select Guest-> Install/Upgrade
VMware Tools. This will mount the media for VMware tools.
• Log into the operating system of the virtual machine and run the VMware tools installer within the OS
running on the virtual machine. See VMware documentation for further information on installing
VMware tools.
The following customization is required for both VMWare and Hyper-V virtual machine
Install the puppet agent on the virtual machine:
• If the virtual machine being used was successfully created by ASM, the puppet agent will already be
installed.
