Note:

XenCenter 2023.x.x is currently in preview and is not supported for production use. Note that any future references to production support apply only when XenCenter 2023.x.x and XenServer 8 go from preview status to general availability.

You can use XenCenter 2023.x.x to manage your XenServer 8 and Citrix Hypervisor 8.2 CU1 non-production environments. However, to manage your Citrix Hypervisor 8.2 CU1 production environment, use XenCenter 8.2.7. For more information, see the XenCenter 8.2.7 documentation.

You can install XenCenter 8.2.7 and XenCenter 2023.x.x on the same system. Installing XenCenter 2023.x.x does not overwrite your XenCenter 8.2.7 installation.

This topic contains information about managing licenses in XenServer.

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:

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

To discover the license status of servers and pools

To see the license type of a server or pool, select that server or pool in the tree view. XenCenter displays the license status in the title bar for that server or pool, after the server or pool name.

You can also go to the General tab of the server and find the license type in the License Details section.

Mixed pools of licensed and unlicensed hosts behave as if all hosts were unlicensed. In the tree view XenCenter displays unlicensed pools with a warning triangle icon.

To assign a XenServer license

  1. From the Tools menu, select License Manager.
  2. Select one or more hosts or pools that you want to assign a license and then select 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.

  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, see the licensing topics on the Citrix Product Documentation website.

XenCenter contacts the specified Citrix License Server and requests a license for the specified servers. If successful, a license is checked out and the information displayed in the XenCenter License Manager is updated.

To release a XenServer license

  1. On the Tools menu, select License Manager.
  2. Select the servers or pools and then select Release License.
