Provision a machine by booting into a WinPE environment and then install an operating system using a Windows Imaging File Format (WIM) image of an existing Windows reference machine.

The following is a high-level overview of the steps required to prepare for WIM provisioning:


Identify or create the staging area. This should be a network directory that can be specified as a UNC path or mounted as a network drive by the reference machine, the system on which you build the WinPE image, and the virtualization host on which machines are provisioned.


Ensure that a DHCP server is available on the network. vCloud Automation Center cannot provision machines by using a WIM image unless DHCP is available.


Identify or create the reference machine within the virtualization platform you intend to use for provisioning. For vCloud Automation Center requirements, see Reference Machine Requirements for WIM Provisioning. For information about creating a reference machine, please see the documentation provided by your hypervisor.


Using the System Preparation Utility for Windows, prepare the reference machine's operating system for deployment. See SysPrep Requirements for the Reference Machine.


Create the WIM image of the reference machine. Do not include any spaces in the WIM image file name or provisioning fails.


(Optional) Create any custom scripts you want to use to customize provisioned machines and place them in the appropriate work item directory of your PEBuilder installation. See Specify Custom Scripts in a PEBuilder WinPE.


Create a WinPE image that contains the vCloud Automation Center guest agent. You can use the vCloud Automation Center PEBuilder to create the WinPE image. See Create a WinPE Image by Using PEBuilder. You can create the WinPE image by using another method, but you must manually insert the vCloud Automation Center guest agent. See Insert the Guest Agent into a WinPE Image.


Place the WinPE image in the location required by your virtualization platform. If you do not know the location, please see the documentation provided by your hypervisor.


Gather the following information so that tenant administrators and business group managers can include it in their blueprints:


The name and location of the WinPE ISO image.


The name of the WIM file, the UNC path to the WIM file, and the index used to extract the desired image from the WIM file.


The user name and password under which to map the WIM image path to a network drive on the provisioned machine.


(Optional) If you do not want to accept the default, K, the drive letter to which the WIM image path is mapped on the provisioned machine.


For vCenter Server integrations, the vCenter Server guest operating system version with which vCenter Server is to create the machine.


(Optional) For SCVMM integrations, the ISO, virtual hard disk, or hardware profile to attach to provisioned machines.


You can create a build profile with the property set WimImagingProperties to include all of this required information. This makes it easier for tenant administrators and business group managers to include this information correctly in their blueprints. Optionally, you can also add the property set SysprepProperties and prompt tenant administrators and business group managers to specify or overwrite settings in the SysPrep answer file.
