2 SysPrep Requirements for the Reference Machine
A SysPrep answer file contains several required settings that are used for WIM provisioning.
3 Preparing for WIM Provisioning with VirtIO Drivers
If you are using VirtIO for network or storage interfaces, you must ensure that the necessary drivers
are included in your WinPE image and WIM image. VirtIO generally offers better performance when
provisioning with KVM (RHEV).
4 Manually Insert the Guest Agent into a WinPE Image
You must manually insert the vRealize Automation guest agent into your WinPE image.
Reference Machine Requirements for WIM Provisioning
WIM provisioning involves creating a WIM image from a reference machine. The reference machine must
meet basic requirements for the WIM image to work for provisioning in vRealize Automation.
The following is a high-level overview of the steps to prepare a reference machine:
1 If the operating system on your reference machine is Windows Server 2008 R2, Windows Server
2012, Windows 7, or Windows 8, the default installation creates a small partition on the system's hard
disk in addition to the main partition. vRealize Automation does not support the use of WIM images
created on such multi-partitioned reference machines. You must delete this partition during the
installation process.
2 Install NET 4.5 and Windows Automated Installation Kit (AIK) for Windows 7 (including WinPE 3.0) on
the reference machine.
3 If the reference machine operating system is Windows Server 2003 or Windows XP, reset the
administrator password to be blank. (There is no password.)
4 (Optional) If you want to enable XenDesktop integration, install and configure a
Citrix Virtual Desktop Agent.
5 (Optional) A Windows Management Instrumentation (WMI) agent is required to collect certain data
from a Windows machine managed by vRealize Automation, for example the Active Directory status
of a machine’s owner. To ensure successful management of Windows machines, you must install a
WMI agent (typically on the Manager Service host) and enable the agent to collect data from
Windows machines. See Installing vRealize Automation.
