What’s new with Provisioning in Excalibur

Patrick Carey wrote a nice blog on the Citrix blogs about the new features in provisioning that comes with the Excalibur Tech Preview available at this time.

One of the benefits of the updated FlexCast Management Architecture is that XenApp farms can now be deployed and managed from within Studio.  This also means they can be provisioned using the Machine Creation Services linked-clone delivery model that has been available within XenDesktop for a few releases now.  One of the primary benefits of MCS is the ease in which new catalogs of machines (virtual desktops and now virtual XenApp servers) can be created.  Updates to the catalog creation wizards in Studio guide you though the initial roll-out of a virtual XenApp farm.  The MCS model provides many of the same single image management benefits of Provisioning Services, but works directly on the storage managed by your hypervisor, so there is no need to deal with PXE or build-out a Provisioning Services deployment.  However, this capability is limited to the new Excalibur version of XenApp.

PVS streaming for XenApp farms and desktop catalogs is still an option in Excalibur, providing the enhanced image management capabilities and storage IO optimizations beneficial in larger, more complex environments, though management of the Provisioning Services infrastructure remains in a separate management console. Provisioning Services will continue to provide a centralized image library for mixed environments where multiple “sites” or “farms” of XenDesktop and XenApp are used.

How to set a unique STA ID in XenApp 6.5 provisioned environment

In a XenApp 6.5 provisioned environment the STA (Secure Ticket Authority) ID is not unique. This is because when a XenApp 6.5 (provisioned) is rebooted the NIC (Network Interface Card) has not completely started and loaded and is not functional when the Citrix services start. Therefor the STA ID is not changed with the MAC Address of the provisioned server (as expected).


Open the Target Device in Read/Write mode and change the startup type to Automatic (Delayed Start) for Citrix XML Service.

XenDesktop and Provisioning Services on vSphere 5

Scott Cochran wrote a good blog post on the Citrix blogs which this is the beginning.

I want to preface this post by saying if you are not interested in any backstory just skip down to the summary section for a wrap up…

Coming from a consulting background I learned the hard way that you always have to check the compatibility of all components in a project.  Since VMware released vSphere 5 many people found out the hard way that Citrix Provisioning Services (PVS) was not supported on VMware’s latest hypervisor platform.  People without in-depth knowledge of the Citrix solution stack may have read XenDesktop 5 was supported on vSphere 5, but in reality that only meant when using Machine Creation Services (MCS).  This forced companies to have to make some hard decisions.  You could either go down the route of using MCS with vSphere 5, or go with Provisioning Services on vSphere 4.x.  Hopefully most customers consulted with their trusted Citrix advisor prior to making this

Provisioned XenApp Servers do not Accept Connections

Provisioned XenApp servers do not accept connections when restarted while the license server is unavailable.

  • Provisioned XenApp servers
  • XenApp 6.0
  • License Edition 11.9

The license server cache file, MPS-WSXICA_MPS-WSXICA.ini, is saved in the %systemroot%Program FilesCitrix folder, which might be unavailable when the server image shuts down and Provisioned XenApp servers refuse to accept connections when they are restarted while the license server is unavailable.
The following are the steps to complete the task:

Save the license server cache file in a shared network location – a location separate from the XenApp server image so that the file is available even when the server image shuts down.
If you save the file in a location away from the server image, you must set the following registry key to point to the cache file location:
Caution! This fix requires you to edit the registry. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.” Continue reading “Provisioned XenApp Servers do not Accept Connections”
