Citrix PVS Image Preparation Script for XenApp 7.x Workloads

Line Break

Author: Frank Peter (97 Articles)

With this post I share a Powershell script that prepares the master installation of a XenApp 7.x Worker for imaging with Citix Provisioning Services, Prepare-XenApp7.ps1.

Due to fact that Citrix has ported its flagship XenApp to the architecture that was introduced with XenDesktop 5, there’s strictly speaking no need to generalize the PVS vDisk that provides the workload of a XenApp Worker because it doesn’t contain IMA-related stuff anymore. On the other hand there’s still room for some optimization steps before putting a XenApp vDisk into production/standard mode. The script automates the following steps:

  • Investigate the PVS’ Personality.ini in the root of the system drive in order to determine the disk mode that is read-write, read-only, or started from local HD
  • Clear Citrix User Profile Manager’s cache
  • Resync time
  • Update GPO settings
  • Clear network related caches (DNS and ARP)
  • Clear WSUS Client related settings
  • Clear event logs
  • Based on the findings in Step 1, suggest a convenient main action, that is either “Exit” (if we’re in maintenance/private w/ read-write vdisk access), or “Invoke ImagingWizard” (if we started from local HD), or “Invoke XenConvert” (reverse imaging scenario w/ read-only vdisk access)

BTW, the script should work for desktop workloads as well but I haven’t tested it so far.

Hope this helps
