KB: Adding a Citrix XenServer host on System Center 2012 Virtual Machine Manager fails with error 2916 (0x8033810f)

KBHere’s a new System Center 2012 Virtual Machine Manager Knowledge Base article we recently published. This one tells you how to fix an issue where adding a Citrix XenServer host on VMM fails with error 2916 (0x8033810f).



Adding a Citrix XenServer host on System Center 2012 Virtual Machine Manager may fail with the following error:

Error (2916)
VMM is unable to complete the request. The connection to the agent <Xen server> was lost.
Unknown error (0x8033810f)
Recommended Action
Ensure that the WS-Management service and the agent are installed and running and that a firewall is not blocking HTTPS traffic.
This problem can also be caused by WMI service crash. Ensure that KB 982293 (http://support.microsoft.com/kb/982293) is installed on the machine if it is running Windows Server 2008 R2.
If the error persists, reboot <Citrix host> and then try the operation again.


This issue occurs if security update MS12-006 (KB2585542) is installed on the VMM Management Server. This security update blocks a WMI call that is used by the Citrix XenServer host.


To work around this issue, perform the following steps on the VMM Management Sever:

  1. Set the SendExtraRecord registry value to 2 by performing the steps documented in the following Microsoft knowledge base article: http://support.microsoft.com/kb/264358


  2. Once the SendExtraRecord registry value is set to 2, add the Citrix XenServer host.
