Managing XenServer 7.5 Licenses

This topic contains information about managing licenses in XenServer 7.5.

All hosts in a pool must be licensed. You can manage your XenServer license using the License Manager dialog box in XenCenter. The License Manager allows you to:

  • Assign XenServer license to managed servers. When you assign a license, XenServer contacts the Citrix License Server and requests the specified type of license. If a license is available, it is then checked out from the License Server.
  • Release XenServer licenses. When you release a license, XenServer contacts the Citrix License Server and checks the license back in.

Important: Citrix XenServer 7.5 requires Citrix License Server v11.14 or higher. You can download the License Server from Citrix Licensing.

To assign a XenServer license

  1. From the Tools menu, click License Manager.
  2. Select the host(s) or pool(s) that you wish to assign a license and then click Assign License.
  3. In the Apply License dialog box, select the license you want to request from the License Server. For more information about various XenServer licenses, see Licensing Overview - XenServer 7.5.
  4. Enter the License Server details and then click OK.

    Note: By default, the License Server uses port 27000 for communication with Citrix products. If you changed the default port on the License Server, enter the appropriate number in the Port number box. For more information about changing port numbers due to conflicts, refer to the Licensing topics on the Citrix Product Documentation website.

XenCenter contacts the specified Citrix License Server and requests a license for the specified server(s). If successful, a license is checked out and the information displayed in the XenCenter License Manager will be updated.

To release a XenServer license

  1. On the Tools menu, click License Manager.
  2. Select the host(s) or pool(s) and then click Release License.
