Installing Supplemental Packs

Supplemental packs are used to modify and extend the functionality of XenServer, by installing software into the control domain (Dom0). For example, an OEM partner might wish to ship XenServer with a suite of management tools that require SNMP agents to be installed, or provide a driver that supports the latest hardware. Users can add supplemental packs either during initial XenServer installation, or at any time afterwards. Facilities also exist for OEM partners to add their supplemental packs to the XenServer installation repositories to allow automated factory installations. For more information, refer to the Developer Documentation.

To install a Supplemental Pack using XenCenter

  1. Download the supplemental pack ( filename.iso ) to a known location on your computer. Supplemental packs are available to download from the XenServer Downloads page.
  2. From the XenCenter menu, select Tools and then Install Update.
  3. Read the information on the Before You Start page and then select Next to continue.
  4. On the Select Update page, click Browse to add the supplemental pack and then click Next to continue.
  5. On the Select Servers page, select the pool or server to which you would like to apply the supplemental pack and then click Next. This uploads the supplemental pack to the default SR of the pool or the server.


    If the default SR in a pool is not shared, or does not have enough space, XenCenter tries to upload the supplemental pack to another shared SR with sufficient space. If none of the shared SRs have sufficient space, the supplemental pack will be uploaded to local storage on each server.

  6. The Upload page displays the status of the upload. If there is not enough space on the SR, an error will be displayed. Click More Info for details and take necessary action to free up the space required for the upload.
  7. After the file is successfully uploaded, XenCenter performs a series of prechecks to determine whether the supplemental pack can be applied onto the selected servers and displays the result. Follow the on-screen recommendations to resolve any update Prechecks that have failed. If you would like XenCenter to automatically resolve all failed prechecks, click Resolve All.
  8. Choose the Update Mode. Review the information displayed on the screen and select an appropriate mode. If you click Cancel at this stage, the Install Update wizard will revert the changes and removes the supplemental pack from the SR.
  9. Click Install update to proceed with the installation. The Install Update wizard shows the progress of the update, displaying the major operations that XenCenter performs while updating each server in the pool.
  10. When the supplemental pack installation is complete, click Finish to close the wizard. The newly installed supplemental pack will be displayed in the Updates section on the General tab of the host or the pool. .
