3.7.1 Microsoft Windows 7 Image Creation and Provisioning
The Microsoft Windows 7 image and additional Software was initially installed and prepared as a standard Virtual
Machine on Citrix XenServer 5.6; prior to each one being converted into separate Citrix Provisioning server vDisk
images and then 100‘s of V clones being created using the XenDesktop setup wizard tool.
The XenDesktop Setup Wizard effectively creates virtual machine objects, configures - RAM, correct Network
assignment and each assigned with a 3GB virtual disk hosted on a datastore mounted on the hypervisor through
NFS from a NetApp provided storage volume. It also creates and configures the relevant PVS, DDC and AD
objects associated with these.
More information as to why the additional virtual disks are needed can be found in the section Configuration
Topology for Scalability of Citrix XenDesktops on the Cisco Unified Computing System and NetApp Storage.
The following section describes the process to create the centralized Windows 7 vDisk image used by
Provisioning Services (Figure 31).
