Upcoming changes in XenCenter

By the end of 2022, the way XenCenter checks for and applies updates to Citrix Hypervisor and XenServer will change. These changes apply to all versions of XenCenter, XenServer, and Citrix Hypervisor.

Review these changes and take the necessary actions to continue to receive support for your Citrix Hypervisor and XenServer deployments.

Upcoming changes

  • Only XenCenter 8.2.6 and later can check for and download hotfixes. Earlier versions of XenCenter will no longer support this capability.
  • You can check for and download hotfixes through XenCenter only if you have set up a client ID for authentication.
  • In effect from Nov 23, 2022: XenCenter can no longer be used to apply updates to the end-of-life XenServer 6.x releases. The hotfix files are still on the Citrix support site, but will shortly be withdrawn.

The changes to XenCenter only affect the downloading and application of updates to Citrix Hypervisor and XenServer. Other XenCenter features are not affected by these changes and will continue to work as before.

What actions do I need to take?

1 – Upgrade to XenCenter 8.2.6

Going forward, only XenCenter 8.2.6 and later will be able to check for and download hotfixes.

Ensure that you upgrade to this version of XenCenter as soon as possible.

It is available from the Citrix Hypervisor downloads site https://www.citrix.com/downloads/citrix-hypervisor/ in the Citrix Hypervisor 8.2 LTSR section. Its release was announced in an article on the Citrix support site: https://support.citrix.com/article/CTX464122/xencenter-826-for-citrix-hypervisor-82-cumulative-update-1

XenCenter 8.2.6 is compatible with Citrix Hypervisor 8.2 Cumulative Update 1 and Citrix Hypervisor or XenServer releases that went end-of-life in 2022.

2 – Set up your client ID in XenCenter

To provide a more secure service for hotfix downloads, XenCenter 8.2.4 introduced a feature that requires authentication with Citrix to automatically download and apply hotfixes.

If you haven’t already set this feature up, do so now.

Complete the following steps to set up this capability on your XenCenter instance:

  1. Check that your Citrix account has the correct permissions to download Citrix Hypervisor hotfixes:
    1. Log in to https://support.citrix.com with your Citrix account
    2. Go to a Citrix Hypervisor hotfix article, for example https://support.citrix.com/article/CTX472925/
    3. Check that you have permissions to download the attached zip file.
  2. If you cannot download the hotfix zip file, contact Citrix Customer Service to ensure that your Citrix account meets the following requirements:
    • You are registered as a contact for your organization.
    • Citrix Customer Service created your Citrix account as a web login associated with the registered contact.
    • Your organization has an active Citrix Success Services agreement.
  3. In the XenCenter menu, go to Tools > Options. The Options window opens.
  4. In the Updates tab, go to the Client ID section.
  5. Click the provided link to go to the page Generate and Download a Client ID in your web browser.
  6. Log in with the Citrix account that you ensured had the correct permissions.
  7. Click the Download Client ID button. The client ID is provided as a JSON file (xencenter_client_id.json).
  8. Return to XenCenter.
  9. In the Location field, browse to the location of the JSON file you downloaded (xencenter_client_id.json) and select the file.
  10. Click OK.

3 – Move your out-of-support XenServer and Citrix Hypervisor deployments to the latest LTSR

Hotfixes for out of support versions of XenServer and Citrix Hypervisor will be removed from the Citrix support site and will no longer be available through XenCenter.

If you are still using an end-of-life version of the product, we strongly recommend that you install Citrix Hypervisor 8.2 CU1 LTSR on your servers instead. Using the latest supported release of Citrix Hypervisor ensures that you continue to receive the latest security and functional fixes for your environment.
